Australia’s AI Data Centre Boom: Wealth Opportunity or Energy Challenge?

Published

on

The AI data centre boom is becoming one of the most controversial new infrastructure developments in Australia. Global technology giants are investing billions, and even tens of billions, of Australian dollars in the country, driving a data centre construction boom worth more than A$150 billion.

Australia has land, renewable energy and a stable institutional environment, making it an ideal destination in the eyes of technology giants. But the enormous electricity, water and infrastructure demands behind data centres are also testing whether Australia can withstand this technology boom.

Will this data centre boom ultimately become Australia’s next wealth opportunity, or will it lead to higher energy and living costs borne by ordinary Australians?

However, before discussing the AI data centre boom, one premise needs to be clarified. This article is primarily based on the AI development model currently widely adopted by large technology companies — relying on high-performance chips, servers and large-scale data centres to provide computing power.

But AI does not necessarily have to follow only this development path. Take Chinese AI company DeepSeek as an example. Its lower-cost approach to model development has prompted the market to rethink whether AI really needs ever-increasing numbers of chips, computing power and data centres. As AI technology continues to advance, demand for large-scale infrastructure may also change in the future.

Why Are Global AI Giants Suddenly Looking to Australia?

In recent years, Australia has become a popular market for AI data centres worldwide, with technology giants stepping up their investments. Amazon’s AWS plans to invest around A$20 billion over the next five years, while Microsoft has also increased its AI investment in Australia to around A$25 billion. OpenAI plans to build the Stargate computing campus in Sydney, while Project Southgate, involving Nvidia, and Anthropic, the developer of Claude, also have plans for large-scale deployments. Although some projects are still in their early stages, Australia is becoming an important market for global AI companies.

There are actually common considerations behind so many technology giants entering Australia one after another. Australia’s conditions happen to meet the development needs of large-scale data centres.

One of the most direct advantages is land. Large data centres do not necessarily need to be located in city centres. Instead, they require large areas of land, as well as access to infrastructure such as power grids and telecommunications networks. There are still many areas around Sydney and Melbourne that can accommodate large-scale projects, making Australia more capable of accommodating increasingly large data centres than land-constrained markets such as Tokyo and Singapore.

The second factor is energy. Australia has abundant solar and wind resources, while what AI data centres need most is large amounts of stable electricity that can be secured over the long term. This means that when technology companies choose the location of their next large data centre, they are no longer considering simply whether there is enough electricity today, but whether electricity supply can continue to increase over the next decade. As a result, Australia’s enormous renewable energy potential has become an important factor attracting technology companies.

Third, Australia’s relatively stable political and legal environment is also an advantage. Once built, data centres often need to operate for many years, so companies naturally want to invest huge amounts of money in a place where the policy and investment environment is relatively predictable. In addition, Australia has close ties with the United States and possesses submarine cables and telecommunications infrastructure connecting Asia and North America, giving it a certain strategic value in the eyes of global technology companies.

The Energy Cost Behind Data Centres

However, the rapid expansion of data centres has also triggered a backlash in Australian society. These facilities require large amounts of electricity around the clock and use water for cooling. As the number of projects continues to increase, residents are beginning to worry: Where will the electricity and water come from? Can the existing power grid cope? And who will ultimately bear the cost of the additional infrastructure?

These concerns are not unfounded. The Australian Energy Market Operator, AEMO, estimates that data centres currently account for around 2% of electricity supplied through Australia’s power grid. But as AI demand increases rapidly, related electricity consumption could grow by around 25% per year, reaching approximately 12 TWh by 2030, accounting for about 6% of national electricity supply. By 2050, this could increase further to around 34 TWh, accounting for approximately 12%. In other words, data centres currently account for only a small share of Australia’s electricity demand, but over the coming decades they could gradually become one of the grid’s major electricity users.

Looking at the scale of individual projects makes it easier to understand the size of the issue. For example, in Plumpton, around 30 kilometres northwest of Melbourne, plans are underway to build a massive data centre precinct covering approximately 350 hectares. Around 140 hectares would be used to build four data centres, making the site almost six times the size of Chadstone Shopping Centre, with a maximum power capacity of up to 2.4 GW. This figure could even exceed the electricity demand of some of Victoria’s large traditional power generation facilities.

This is not an isolated case. Australia currently has more than 160 data centres in operation, most of them concentrated in New South Wales and Victoria, while at least another 90 projects are being planned or prepared. AEMO estimates that by 2030, data centres could account for around 11% of available electricity in Sydney, significantly higher than the current figure of around 4%. Melbourne also faces a situation worth watching closely. By then, data centres could consume around 8% of Victoria’s electricity, more than four times the current level.

And this is where AI data centres are most controversial: the issue is not whether Australia has the capacity to supply electricity, but whether Australia can increase generation, transmission and energy storage infrastructure quickly enough when dozens or even hundreds of large data centres emerge at the same time. If data centre growth far outpaces the construction of new renewable energy and grid infrastructure, the AI boom could become not just a technology investment boom, but a race to secure energy supply.

The Resource That Is Often Overlooked: Water

In addition to electricity, data centres have another easily overlooked “hidden cost” — water.

AI servers generate large amounts of heat when operating at high speeds for extended periods, so data centres must continuously provide cooling. Some cooling systems require large amounts of water, and as the computing power and energy consumption of AI equipment continue to increase, cooling requirements may also rise further.

Infrastructure Australia estimates that a large data centre of around 250 MW could use an amount of water each year equivalent to the household water consumption of between 5,000 and 35,000 homes, depending on the efficiency of its cooling system. Sydney Water also estimates that if the currently proposed data centre projects are developed on a large scale, Sydney’s data centres could require around 90 billion litres of water each year by 2035, equivalent to approximately 15% to 20% of Sydney’s current water supply.

For a country already facing drought, population growth and climate change, this is not a small figure. When data centres compete with households, agriculture and other industries for the same water resources, the question is no longer simply whether Australia should develop AI, but how many resources Australia actually has available to support this AI boom.

The impact of data centres therefore extends far beyond the technology sector. It involves energy, water resources, land and urban planning, and could ultimately affect the cost of living for ordinary households.

The Australian Government’s Solution

Faced with the electricity, water and infrastructure pressures created by the rapid expansion of data centres, the Australian federal government is attempting to establish nationwide rules.

In March this year, the government first announced a policy framework for data centre and AI infrastructure developers, covering areas including energy, water resources, national interest, local employment, research and innovation. In July, it proposed nationwide AI data centre standards. Last month, the National Cabinet also agreed to develop nationally consistent mandatory standards for energy, water resources and land use, with the government planning to legislate formally in early 2027.

The core concept of the policy is straightforward: data centres can invest in Australia, but they cannot leave the additional costs to society. The government wants large data centres to bear the costs of additional electricity supply and grid connections themselves, have the ability to adjust their electricity consumption when the grid is under pressure, reduce water consumption, and take into account the impact of projects on housing, schools, farmland and nearby communities.

One of the most closely watched requirements is the “bring-your-own-power” requirement. Under this approach, new large data centres would need to use renewable energy as their primary electricity source, together with sufficient backup power to ensure stable operations even when wind or solar generation is insufficient. In other words, the federal government wants to ensure that data centre expansion does not run ahead of Australia’s energy transition.

However, the federal government’s direction is not fully accepted by all states. Queensland and the Northern Territory want to use existing coal and gas-fired generation facilities to supply electricity to data centres. The reason is practical: these large projects represent enormous investment and economic activity, and state governments worry that if regulations are too strict, companies may invest elsewhere.

As a result, the latest national proposal ultimately retains some flexibility. The data centre standards do not completely rule out coal and gas. Energy Minister Chris Bowen said that if state governments can demonstrate that their existing coal and gas generation mix can provide cheaper electricity than renewable energy, the federal government would consider limited exemptions.

Can the Government’s Plan Really Solve the Problem?

On the surface, the federal government’s plan appears to have answered the most fundamental question: data centres cannot use public resources without limits, and the additional costs of energy and infrastructure should also be borne by companies themselves. But the real challenge is that requiring data centres to “bring their own power” does not mean Australia will suddenly have more electricity as a result.

Even if technology companies are willing to invest in solar, wind or batteries themselves, these energy projects still require land, transmission lines and other grid infrastructure. Planning, approval and construction can also take years. In other words, if data centres are built faster than renewable energy and grid infrastructure can expand, even if companies are willing to pay the associated costs, they may not be able to obtain enough clean energy in time.

More fundamentally, data centres are only one part of Australia’s future growth in electricity demand. As electric vehicles become more widespread, households gradually switch to electric appliances, businesses become further electrified, and the population continues to grow, overall electricity demand will also increase. Therefore, even if the government successfully limits the impact of data centres on the grid, this policy alone cannot solve Australia’s broader electricity supply problem.

The challenge Australia faces is not simply “what kind of electricity should data centres use?” It is whether the country’s entire electricity system can keep up with continuously rising future demand. If the construction of renewable energy, batteries and transmission networks continues to lag behind demand, even the strictest data centre standards may only limit electricity consumption without actually increasing supply.

Therefore, whether this policy succeeds will ultimately depend not only on whether the government can establish rules, but also on whether Australia can build the necessary energy and infrastructure in time before AI investment reaches a large scale. Otherwise, “bring your own power” could ultimately become a promise that sounds reasonable but may not be easy to fulfil.

Another Test: National Security

In addition to energy and water resources, the rapid expansion of AI data centres also raises another issue that cannot be ignored — national security and data security.

Data centres store and process large amounts of sensitive information, including government information, corporate data and personal information. As AI computing increasingly relies on large-scale data centres, if these facilities are subjected to cyberattacks, data breaches or even interference by foreign forces, the impact may extend beyond individual companies and potentially involve Australia’s critical infrastructure and national security.

Especially when large data centres are operated by overseas technology companies, the Australian government needs to consider not only how much investment these companies bring, but also who controls these infrastructure assets, where the data is stored, and the extent to which Australia can maintain control over its own AI computing capacity.

If the government focuses only on the speed of investment while failing to establish appropriate regulation and supporting measures in time, the economic opportunities brought by AI could also come with new social and security costs.

The Economic Opportunities Brought by Data Centres

CommBank estimates that data centre investment will become an important driver of growth in Australian business investment over the coming years. In 2026 and 2027 alone, related investment is expected to contribute around 0.2 percentage points to real GDP growth each year.

From construction through to ongoing operations, data centres will also create jobs, including for electricians, engineers, cooling system technicians, construction workers, network engineers and facilities management personnel. As large-scale projects are progressively developed, demand for relevant skilled workers in Australia will also increase.

However, data centres remain a highly capital-intensive industry. A single facility can involve billions of Australian dollars in investment, but once built, it does not require a large workforce. Meanwhile, core hardware such as AI chips, GPUs, servers and high-end networking equipment currently relies heavily on overseas imports.

In other words, overseas technology companies can invest in and build data centres in Australia. Australia can certainly benefit from construction, engineering, land, energy and some tax revenues, but the higher-value technologies, products and profits within the AI industry supply chain may not all remain locally.

Therefore, what Australia should truly seek is not simply how much investment data centres themselves can bring, but how these infrastructure assets can be used to further expand the domestic AI industry.

Letting Data Centres Drive the Development of Different Australian Industries

As demand for AI computing continues to increase, data centres can provide Australian businesses, universities, research institutions and start-ups with greater access to GPU computing power and cloud resources, making it easier for local AI technologies to move from research into commercialisation. The government’s “Buy Australian AI Partnership” also aims to increase the adoption of Australian AI products by local businesses and banks, further expanding the domestic AI market.

If these investments can form closer partnerships with local businesses, talent and research institutions, Australia could further develop talent and technology on the basis of its existing AI industry, and even take locally developed AI products to overseas markets.

At the same time, the enormous energy demand of data centres could also drive another supply chain.

AI requires stable and large amounts of electricity. In the future, demand for solar power, wind power, battery storage, transmission equipment, transformers, microgrids and energy management technologies will all increase. With its advantages in land and energy, Australia is well positioned to further develop the energy and infrastructure needed to support AI computing.

If this cycle can be established, the benefits brought by data centres will go beyond the investment itself. Technology companies’ demand for electricity and computing power can drive the development of renewable energy, the power grid and related technologies, while more advanced infrastructure can in turn improve the competitiveness of other businesses and industries.

Conclusion: Can Australia Become the AI Hub of the Southern Hemisphere?

For a country with vast land, relatively low population density and abundant energy resources, AI data centres are actually well suited to development in Australia.

But faced with investments worth billions or even hundreds of billions of Australian dollars, Australia does not need to move as quickly as possible. It needs to make more careful choices. The government should not focus only on investment and economic growth and rush to accept every data centre proposal. Instead, when approving large data centres, it should also take a long-term planning approach and assess the risks that future data centre expansion could pose to energy, the environment and national security.

More importantly, the costs of the AI boom cannot ultimately be passed on to Australian residents. Whether it is pressure on electricity and water resources, public infrastructure expenditure, or the impact of land development, carbon emissions, environmental pollution and ecosystems, ordinary households and local communities should not be made to bear the costs of large-scale technology investment.

If Australia can attract AI investment while requiring companies to bear the corresponding energy, infrastructure and environmental costs, and transform investment into the long-term development of local talent, research and the AI industry, data centres could bring more than just another infrastructure boom. They could allow Australia to make use of its land, energy, talent and existing AI advantages and, as AI reshapes the global industrial landscape, establish a more competitive and sustainable development model.

Only when a balance is achieved between economic opportunities and social and environmental costs will Australia have the opportunity to move from being a destination that attracts global AI investment to becoming an AI hub in the Southern Hemisphere that connects Asia with global markets and possesses domestic AI capabilities.

Have We Asked the Right Questions After the Tragedy?

Published

on

A Look at Political Safety, Mental Health, and Journalism Ethics Through the Attack on MP Helen Haines

Data current as of October 21, 2026. The case is still before the courts, and the accused man has not been convicted.

On October 19, 2026, federal independent MP Helen Haines was attacked outside her electorate office in Wangaratta, Victoria, when a car was driven into her. Aged 65, she represents the northeastern Victorian electorate of Indi. She has suffered severe injuries, resulting in the amputation of both her legs. This is a heartbreaking tragedy, and the victim and her family deserve the full support of the entire community.

In the wake of this tragedy, beyond caring for the victim, we should ask another question: when the motive remains undetermined, how do politicians and the media explain what happened to the public? Are we striving to understand a complex case, or are we prematurely fitting it into pre-existing political narratives?

This is a question for politicians, and it is also a question for the journalism profession.

What We Know and What We Don’t Know

What is known (based on reports from police, courts, and mainstream media):

Monday, October 19, around 3:35 PM: Haines was struck by a white Toyota LandCruiser outside her electorate office. According to eyewitnesses, after striking her, the vehicle turned around and hit her a second time.

She was transported to The Alfred Hospital in Melbourne. Her left leg was amputated on the day of the incident, and her right leg could not be saved as of the afternoon of October 21. Her husband stated that her condition is stable.

A 43-year-old man from Tarrawingee has been charged with three offenses: dangerous driving causing serious injury, intentionally causing serious injury, and injuring a Commonwealth public official. He did not apply for bail and will appear in court again next February. Police have not ruled out further charges, including attempted murder.

Police stated that the attack was deliberate but appears to be an isolated incident, with no prior specific intelligence indicating he would target Haines. At the same time, a Joint Counter Terrorism Team comprising Victoria Police, the Australian Federal Police (AFP), and ASIO is investigating, with establishing whether there was a political motive listed as a top priority.

Victoria Police Chief Commissioner Mike Bush stated that police are reviewing social media connections and speaking with witnesses, friends, and colleagues, while also investigating whether there was any personal relationship between the parties. Statements issued by the accused man’s father and partner noted that Haines has been a friend of theirs for over twenty years.

In court, his lawyer mentioned that he suffers from a neurological condition and a concussion, raising concerns about his mental state. However, he has not been diagnosed with any mental health conditions, and when asked if he had been evaluated by a doctor, the lawyer stated it was “unclear.”

What is unknown:

What was the motive? Was it politically motivated?

Was there any personal relationship between the two parties?

What was his mental state, and was it related to the incident?

Did anyone seek help from relevant agencies beforehand? What actions, if any, did those agencies take?

This list is vital because all subsequent discussions must remain within its boundaries.

What Politicians Are Saying

Following the incident, Prime Minister Anthony Albanese stated that it was a deliberate attack, but the motive remained unclear. He subsequently issued another call for all sides to “tone down the temperature.” Opposition Leader Angus Taylor remarked, “We do not resolve differences through violence.”

Statements from other MPs went further. Minister for Finance Katy Gallagher noted that standards in Parliament have declined, fueled by “algorithmic amplification” on social media that intensifies online piling-on. MP Zali Steggall attributed the heightened tension to online polarization and talkback radio hosts. According to reports, Eden-Monaro MP Kristy McBain shared that she has added a personal alarm and altered her daily routines and travel routes; in her electorate alone, three individuals have been arrested for threatening an MP.

These concerns are not unfounded. The threats faced by parliamentarians are real, and the involvement of the Joint Counter Terrorism Team demonstrates that authorities take the matter seriously. Safeguarding democratic institutions includes ensuring that elected officials can safely engage with their constituents.

However, the problem lies here: while the motive behind the event remains unknown, the narrative of “political culture” has already become the central axis of public discussion. Can a single case prove that political violence in society is on the rise? We need to distinguish between three things: known facts, reasonable speculations, and judgments yet to be verified.

What the Media Did and What It Missed
To be fair: many media outlets did a respectable job. In the days following the incident, mainstream media reported on the charges, police statements, counter-terrorism investigations, the defense lawyer’s statements regarding neurological conditions and concussions in court, as well as the statement from the accused man’s family. Some reports also quoted neighbors saying there had been shouting heard at the residence and that police had visited multiple times.

Yet, we also saw another side. Take a news agency report—which we read and saw republished by multiple outlets—as an example: it quoted several MPs criticizing online polarization and algorithms, but failed to cite any official threat statistics or quote any political figures urging caution while the motive remained unclear. Another media outlet ran a headline directly linking the event to an “aggressive political culture.” Every quote in these reports may well have been accurate, but taken as a whole, what readers primarily absorbed was the politicians’ interpretations.

This is merely our observation within a limited scope, not a comprehensive statistical study of all media coverage. Truly assessing overall balance would require a more systematic comparison. But this question is worth asking:

Reporting on a context and fully analyzing a context are not the same thing. Including a piece of information in the news does not mean it received sufficient space, placement, or follow-up.

While the motive remains unclear, journalists can press further: Is this an established fact, or a politician’s judgment? Are there other possible explanations? What do current data support, and what do they fail to support?

Do Not Let Politicians’ Safety Replace Community Safety
The safety of MPs deserves serious attention. However, political figures are not the only individuals facing risks.

This incident also brings up another issue: Can individuals in the community experiencing severe crisis receive appropriate support in a timely manner?

Caution is necessary here. Mental health issues cannot be equated with violence; the vast majority of people with mental health conditions do not commit violent acts against others. The accused man has not been diagnosed with a mental health condition; what his lawyer presented were concerns and a request for evaluation. Descriptions provided by neighbors and past acquaintances represent piecemeal observations—these are individual perceptions, not medical diagnoses, and certainly not proof of motive. We cannot assert from this that shortcomings in the mental health system were the cause of this case.

However, this does not mean we should stop questioning public policy. Victoria has undergone a Royal Commission into Mental Health and subsequent reform commitments. The government has a responsibility to account to the public on the extent to which these reforms have been implemented and whether community services are adequate. If investigations reveal that concerns had been raised previously and relevant agencies failed to intervene, we must ask: How well is the support system functioning? Is there coordination across departments?

These questions should not be set aside simply because the safety of political figures has taken center stage, nor should conclusions be drawn prematurely before investigations are complete.

The Risk of Prematurely Defining Meaning

Social division is not a label that can be arbitrarily applied.

When a tragedy occurs, the public naturally wants to understand why. Politicians and the media also need to offer explanations. However, if people rush to frame the event within grand narratives like “political hatred is rising” or “society is deeply polarized” before evidence is sufficient, the public may mistake unverified judgments for facts.

This does not mean political violence does not exist. The three arrests mentioned by McBain and the added security measures taken by MPs demonstrate that threats are real. But asserting that political violence is on the rise requires long-term data: how many threats against MPs have occurred, what were their sources, what were the motives, and how have these numbers changed over recent years? Relying on a single case is insufficient to answer this question.

Asking these questions does not diminish support for the victim; rather, it protects the public’s right to understand the incident clearly.

What Does This Incident Have to Do with Us?

This matter is not far removed from the Australian Chinese community.

First, on November 28, Victoria will hold its state election. During election periods, candidates hand out flyers, hang posters, and engage with voters on the streets and in local neighborhoods. This is a staple of a democratic society, as well as the time when candidates are most exposed to risk. How the community protects this openness is something worth pondering.

Second, Chinese-language media carry the same responsibility. We frequently translate and republish English-language news. If we merely translate politicians’ statements without marking the boundaries between “what is known” and “what is unknown,” we become part of the problem.

Third, mental health remains a taboo subject in many Chinese families. When discussing this incident, we must be especially careful not to link mental health issues directly to violence, lest we deepen existing stigma.

Finally, there is a image worth remembering: on the day of the incident, local residents at the scene stepped in to help restrain the suspect, and emergency responders quickly attended to the injured. Community safety relies not only on institutions and governments, but is also built on the willingness of ordinary people to help one another in moments of crisis.

Scrutinize Rather than Just Transcribing Power

This tragedy should not be used to downplay the threats faced by MPs, nor should it be used to argue that a particular political camp inevitably causes violence, and it certainly should not serve as a reason to ignore mental health services, community support, and public institutions.

We can acknowledge three things simultaneously:

The attack on Helen Haines was extremely severe;

The motive must be established by evidence through investigations and the courts;

The interpretations of the event by politicians and the media should themselves be subject to public scrutiny.

For politicians, the responsibility is not to package unverified judgments as definitive conclusions. For the media, the responsibility is not to let politicians’ statements become the endpoint of reporting.

A mature democratic society needs safe elected representatives, as well as a news media unswayed by political narratives; it needs to condemn violence, while maintaining the ability to make rational judgments free from fear.

When tragedy strikes, what truly warrants our vigilance is not just the tragedy itself, but whether we still retain the capacity to ask the right questions.

When politicians rush to explain an event, the media’s most important job is precisely to ask: What do we actually know, and what remains unknown?

Forever a “Guest”? How Hakka People Find a Home

Published

on

Imagine a Sunday afternoon in a living room in Richmond, Melbourne. An elder calls their grandchild to dinner in Hakka, mixing in a few Portuguese words, and the grandchild responds in English. This elder was born in East Timor, has Chinese ancestry, and now lives in Australia. If someone asked, “Where are you from?”, they would probably have to think for a moment before knowing where to begin: Hakka, Chinese, East Timorese, or Australian?

Hakka people are generally regarded as a linguistic and cultural group within the Han Chinese, yet for centuries they were often called “guests” by the Han Chinese around them. “Guest” means you are not someone who was originally from here; “home” means you have already put down roots. This contradiction is one of the most important aspects of Hakka history to understand. And when these “guests” migrate again to Australia, how do they redefine where they belong? This question is in fact also an issue that Australian society faces today.

If They Are All Han Chinese, Why Were They Still Divided into “Local” and “Guest”?

The most common account of Hakka history is that their ancestors migrated south from the Central Plains because of warfare, passing through Jiangxi and Fujian to Guangdong, before later moving overseas. But modern research reminds us that this was not a group of people with a pure lineage moving in an orderly fashion. Rather, it was a community that gradually formed through migration, language and competition over local resources.

In parts of southern China, those who settled earlier were known as the “locals” (Punti), while those who arrived later were called “guests”. Flat and fertile land was already controlled by established clans, so later arrivals could only develop the hilly and mountainous areas. As a result, they developed close clan organisations and fortified communal residences for defence. In the mid-19th century, Guangdong also saw large-scale armed conflicts between the “locals” and “guests”. This shows that even when people belong to the same Han Chinese group, differences in language and clan, and competition for the same land, can turn people into “us” and “them”.

When a place could no longer accommodate everyone, another option was to leave again. Hakka history describes a group of people who repeatedly became outsiders, and how, wherever they went, they built a home again.

Hakka People Were Already in Australia’s Goldfields

During the Australian gold rush of the 1850s, large numbers of Chinese people travelled from southern China to Victoria and New South Wales. By 1861, there were more than 38,000 Chinese people across Australia, accounting for about 3.3% of the non-Indigenous population. Today, it is easy to collectively describe them as “Cantonese”, but the Chinese communities at the time were actually highly diverse.

Most came from the Siyi (Taishan, Kaiping, Xinhui and Enping) and Sanyi areas of the Pearl River Delta in Guangdong, and spoke different Cantonese dialects. At the same time, there were also significant numbers of Hakka people. Historical records from Victoria’s goldfields show that Chinese miners spoke more than ten languages or dialects, with Hakka being one of them. Some Hakka people came from counties different from those of the Cantonese communities, and had differences in language, customs and clan networks. In fact, the existing “local–guest” tensions in southern China were sometimes also brought onto the goldfields, showing that even among Chinese people, internal boundaries still existed.

But what the colonial government and mainstream white society cared about was not whether you were Hakka, Siyi or Cantonese. To them, everyone was first and foremost “Chinese”. In 1855, Victoria began imposing an entry tax on Chinese people and established the Chinese Protectorate, placing Chinese people in designated camps for management. In 1861, serious anti-Chinese riots broke out at Lambing Flat in New South Wales, today known as Young. When the federation was established in 1901, the White Australia policy put exclusion into law.

This created a contrast in identity: in southern China, Hakka people were constantly reminded that they were different from the locals; in Australia, the outside society instead grouped everyone together, and into a group that was excluded. Internal boundaries that had originally been important suddenly became smaller in another country, but they did not disappear completely.

East Timorese Hakka: A Forgotten Part of History

By the latter half of the 20th century, Australia welcomed another particularly distinctive group of Hakka migrants: Chinese people from East Timor.

The history of Chinese people in East Timor can be traced back hundreds of years. Early Chinese merchants travelled to Timor through the sandalwood trade. Later, increasing numbers of Chinese people from southern China settled there, and Hakka people gradually became the main group within the local Chinese community. Before the Indonesian invasion in 1975, there were around 20,000 Chinese people in East Timor, many of them Hakka. They retained the Hakka language, Chinese festivals and family culture, but their places of birth, life experiences and social relationships had become closely connected with East Timor, forming an East Timorese Chinese community with its own history.

1975 was a turning point in the fate of this community. After Portugal ended its colonial rule, East Timor fell into political turmoil, and in December of the same year, Indonesian forces invaded. The Chinese community was severely affected. Some people were killed, property was destroyed, and large numbers of families fled. It is estimated that in the early stages of the invasion, several hundred Hakka people were killed in Dili alone.

Their escape routes were highly dispersed. Some first went to other parts of Indonesia; some travelled through Portugal, Macau or Taiwan before moving on to Australia; others arrived directly in Darwin by sea. After 1975, the first wave saw more than 2,500 East Timorese people, including large numbers of Hakka Chinese, arrive in Australia. Later, between 1979 and 1986, nearly 5,000 more people came to Australia through a special humanitarian program, most seeking to reunite with family members. They mainly settled in Sydney, while significant numbers also settled in Melbourne and Darwin. Areas around Richmond and Flemington in Melbourne gradually developed more visible communities.

These East Timorese Hakka migrants brought not only the Hakka language and Chinese culture, but also shared memories of war, exile and the independence movement. They established their own community organisations in Australia, worked to maintain their language and culture, and also actively participated in activities supporting East Timorese independence. Compared with other Chinese communities, they often placed greater emphasis on their distinctive identity as “East Timorese Hakka”, rather than simply integrating into the broader “Chinese” or “Chinese migrant” community.

This reminds us that “Hakka” has never necessarily been tied to a particular country or piece of land. What has truly been passed down is often language, family memory, and the community relationships that remain after repeated migrations.

Does the “Local–Guest” Divide Still Matter in Australia?

Australia’s Hakka people came at different times: pioneers of the gold rush, refugees from East Timor, and more recent international students and skilled migrants. Although they may all have Hakka backgrounds, they have not necessarily formed a unified Hakka community.

The reason lies in Australia itself. When survival is no longer dependent on “who arrived first” or “who is local”, this boundary loses its strongest foundation. Hakka people from the gold rush era gradually integrated into the broader Chinese and Australian societies over generations. East Timorese Hakka people formed closer communities through their shared language and experiences of exile, but the next generation likewise grew up in English-language education. In recent years, people with Hakka backgrounds have generally first entered the circles of new migrants or professionals.

Hakka people have not disappeared, but Hakka identity is becoming increasingly dispersed. Perhaps what is truly fading is not the Hakka people, but the boundary that once divided people into “locals” and “guests”.

However, saying that Australia has completely eliminated the distinction between locals and guests would be too optimistic. The original owners of this land are Indigenous peoples. From this perspective, all later arrivals, including Chinese people, are “guests” on this land. From the anti-Chinese discrimination of the gold rush era to the fact that some Asians are still told today to “go back to where you came from”, it shows that the question of “who counts as one of us” does not automatically disappear.

What the Hakka Story Can Teach Australia Today

Australia itself is a society made up of many migrant communities. Irish, Italian, Greek, Vietnamese, Lebanese, Chinese, Indian and other communities that arrived at different times have all faced similar questions: after how many generations does an outsider stop being an outsider? Can a person belong to several places at the same time?

Hakka history does not offer a simple answer. What is interesting is that the name “Hakka”, which originally carried the meaning of being an outsider, was ultimately actively embraced by many people. A name that was once used to say “you are not from here” became “this is who I am”.

Today’s Australia does not need different ethnic groups from around the world to each form new Hakka-like communities. What we need more is a set of shared Australian values accumulated over generations and genuinely embraced by newcomers. These values are not the cultures, customs or lifestyles of our places of origin, but the basic principles that every migrant publicly expresses their commitment to and support for when becoming a citizen: democracy and the rule of law, equality of opportunity, respect for others, and the ability to live together amid differences.

How Should Australian Society Respond to Different “Hakka”?

Looking back at these different “Hakka”, we find that there is almost no single common form. This reminds us that there is no single “Hakka community” that can be understood through one label. Likewise, there is no single “Chinese community” or “migrant community”.

The question is not a binary choice between “assimilation or preserving everything separately”. The lesson from Hakka history is that identities can overlap. The real question is: what connects people across these different identities?

Two Pillars: Shared Values and Intercultural Contact

The first pillar is shared Australian values. This does not require everyone to give up their existing languages and cultures, but rather a set of basic principles that everyone is willing to follow and that everyone is protected by: democracy and the rule of law, freedom of speech and religion, gender equality, respect for differences, and the “Fair Go” principle that everyone should have equal opportunities. Without a common framework, diversity can easily become everyone talking past one another. With it, Hakka people can speak Hakka while also saying: this is my country.

The second pillar is genuine intercultural contact between different communities. Going to school together, working together, volunteering and participating in community activities are often more effective than relying solely on slogans.

Intercultural Democracy

The concept of “intercultural democracy” being advocated today combines these two pillars: within a shared democratic and values-based framework, allowing different cultural communities not merely to coexist, but to genuinely interact with one another and participate together in public affairs.

Multiculturalism recognises and respects differences, and this is an important starting point. But if it stops at preserving communities separately, different groups may still remain unfamiliar with one another. Intercultural democracy needs to take one further step, allowing people from different backgrounds to discuss, decide and take responsibility together on an equal basis.

This is the direction that Australia needs to continue discussing today, and one that needs people to speak clearly about in parliament. When some people once again advocate for a “return to a single culture”, we need to remember that what can truly make society stable is not eliminating differences, but building a framework in which differences can coexist and move forward together.

Conclusion

The Hakka people’s centuries-long history of migration is a history of “how to go from being a guest to becoming one of the people who belong”. Australia does not need to repeat those costs.

When facing all kinds of newcomers and later arrivals, the answer is neither to make everyone the same nor to allow every group to build its own fortified village around itself. Instead, we need to establish two things: a set of Australian values that everyone follows together, and a social environment where different communities can genuinely meet, talk and work together. This is intercultural democracy.

In such a society, “local” and “guest” would no longer determine who has the right to stay, but would become roles of mutual respect. Everyone can be a guest in someone else’s home, and can also be a host in their own community, while becoming fellow travellers on this shared land.

If the centuries-long migration of the Hakka people tells us anything, it is perhaps this: “guest” and “home” were never necessarily two opposing things.

Britain Talks Division: Could Australia Have Another Western Australia?

Published

on

If a place has its own government, parliament, as well as a unique history, culture and identity, could it one day choose to leave the country it belongs to?

This question has recently once again become a focus of British politics. On September 14, political leaders from Scotland, Wales and Northern Ireland held a summit and signed a joint memorandum, collectively putting forward demands for self-determination and calling for greater powers for each region to decide its own constitutional future.

These remarks may carry an element of political declaration, but the issue they reflect is not limited to the United Kingdom. When regional governments, parliaments and identities gradually take shape, where should the boundary of power between regions and the central government lie? If self-determination and independence are brought back onto the political agenda across the UK, could an Australian state one day also leave the federation?

Different Histories, Different Identities

To understand why the UK has seen this debate over independence and self-determination, it is first necessary to understand that the UK itself was not a country gradually built around a single nation and a single political centre. England, Scotland, Wales and Northern Ireland each have different histories, cultures and political identities.

Scotland was originally an independent kingdom, with its own legal system, educational traditions and political history. It was not until 1707 that it united with England to form the Kingdom of Great Britain. Wales, meanwhile, was conquered by England and incorporated into its rule at the end of the 13th century, and its language and cultural traditions also came under pressure. Northern Ireland was also occupied by England and experienced a long history of British rule, population movements, religious divisions and political conflict.

For Scotland, Wales and Northern Ireland, regional identity already has deep historical and cultural roots. Political demands for autonomy or independence have, to some extent, also been built on these existing identities. Regional identity did not suddenly emerge because of political disputes in recent years, but has long existed within society.

In other words, today’s UK is a country formed through the long-term political integration of different historical communities, and these histories themselves have shaped how local societies understand identity, power and central rule. When these identities come into conflict with the power of the central government, cultural policies or national identity, existing regional identities may further develop into political demands for autonomy, self-determination, or even independence.

Devolution

This history also influenced Britain’s later political system. Beginning in the 1990s, the UK introduced “devolution”, establishing regional parliaments and governments in Scotland, Wales and Northern Ireland and transferring some domestic powers back to the regions. Policies on education, healthcare and transport, among others, can in part be decided by local governments, while foreign affairs, defence and matters concerning the UK’s overall constitutional arrangements remain largely under the control of Westminster.

Devolution was originally intended to give regions greater autonomy, but it also made regional political identities more visible. Once regions had their own parliaments and governments and could handle many policies themselves, demands for further powers, and even political space to discuss independence, also increased. Scotland held an independence referendum in 2014. At the time, 55% of voters supported remaining in the UK, while 45% supported independence, but the issue of independence did not disappear as a result.

In recent years, nationalist parties in Scotland, Wales and Northern Ireland have gained greater political influence, bringing this constitutional debate back into focus. The political objectives of the three regions are not exactly the same. Scotland and Wales mainly debate independence, while Northern Ireland involves Irish reunification. But all three share one common demand: that the central government should further recognise the regions’ right to determine their own constitutional futures.

The Differences Between Local Autonomy in the UK and Australia

Looking back at Australia, we can also see a similar institutional arrangement. Scotland, Wales and Northern Ireland have their own parliaments and governments, while Australia’s states also have their own state governments and parliaments.

The key difference worth comparing is the position these regional governments occupy within the overall national system. Scotland, Wales and Northern Ireland have gained a certain degree of autonomy within the sovereign state of the UK through devolution. Australia’s six states, by contrast, are themselves important components of the federal system, with the powers of state governments divided and protected by the Australian Constitution. In other words, both sides have regional autonomy, but the historical and constitutional foundations that created this autonomy are different.

What makes Australia particularly distinctive is that, in addition to the federal and state levels, there are also local governments, creating three levels of government: federal, state and local. Each level is responsible for different areas of affairs, allowing political power to be distributed across different levels. For ordinary residents, issues such as education, healthcare and public transport can be handled by state governments, while local roads, planning and community services are handled by local governments. National matters such as defence, foreign affairs and immigration are handled by the federal government.

For an Australian state, moving from a federal system to a sovereign country would not simply mean expanding the powers of the state government slightly further. It would mean crossing an entire set of national-level institutional issues involving law, population, defence, foreign affairs, currency and borders.

Western Australia Once Considered Leaving Too

Compared with the UK, Australia has a shorter history. Before federation was established in 1901, the six states were originally separate British colonies, each with its own government and parliament, before later forming Australia through the federal system. Western Australia, in particular, once sought to leave the Australian Federation because of dissatisfaction with the federal system.

Western Australia was the last colony at the time to decide to join the federation. The gold rush in the late 19th century drove rapid population and economic growth, but Western Australia was geographically distant from the eastern states, and its economic structure and local interests were also different. The state had abundant mineral resources and vast areas of land. As resource development continued, Western Australia later became an important resource and export base for Australia. Iron ore, gold, natural gas and lithium remain important pillars of Western Australia’s economy today.

However, joining the federation did not eliminate the differences between Western Australia and the eastern states. In 1900, Western Australian voters voted in favour of joining the federation, but after federation was established, disputes over tariffs, resources and economic interests continued. Some Western Australians believed that Western Australia provided large amounts of resources and export revenue to the country, but federal policies did not necessarily adequately reflect local interests. As these grievances accumulated, the idea of leaving the federation regained attention in the 1920s, while the Great Depression further deepened dissatisfaction with the federal system among some Western Australians.

By 1933, this separatist sentiment finally reached the stage of a referendum. Western Australia held a referendum on April 8 on leaving the Australian Federation, with more than two-thirds of voters supporting separation. The Western Australian government subsequently sent a delegation to Britain to seek support, but the British side ultimately considered that Western Australia could not legally leave the federation without the approval of the Australian Parliament. Western Australia ultimately remained part of the Australian Federation.

Could Western Australia Become Independent Today?

Whether Western Australia could become an independent country today can be considered from four aspects: law, population, the economy, and identity.

(1) Law

To discuss whether Western Australia can leave Australia, we can first return to the establishment of the Australian Federation. Before 1901, Australia’s six states were still British colonies, each with its own government, parliament and legal system. They were not a unified country. As there was a need to handle matters such as defence, immigration and trade collectively, the colonies eventually chose to form a federation and establish Australia as a common country under the same system.

Once this federal system was established, whether a state could leave on its own was no longer simply a matter that could be decided within the state. The Australian Constitution does not specify how existing states can leave the federation. Instead, its opening provisions describe the Australian Commonwealth as “indissoluble”, meaning indivisible. In other words, the current Constitution does not provide a legal procedure for a state to independently withdraw from the federation.

If a state were to legally leave Australia, the Constitution would first have to be amended, and constitutional amendment requires a national referendum. In addition to receiving support from more than half of voters across Australia, a majority of voters in a majority of states would also have to support it. This arrangement in fact reflects the way the federation was originally established: since Australia was formed as a federation through the agreement of different colonies, changing the constitutional arrangements of the federation itself cannot be decided unilaterally by just one state.

Therefore, even if Western Australia held its own referendum and obtained majority support, a state-level vote alone would not be enough to complete secession. If Western Australia were genuinely to leave Australia, it would need not only the consent of Western Australians, but also the agreement of the entire federal political community to a change in the constitutional arrangements. Therefore, under the current system, it is not simple for an Australian state to move towards independence.

(2) Population

But assuming that this legal obstacle were genuinely resolved one day, would Western Australia have the basic conditions to become a country?

Population is one important factor. As of March 2026, Western Australia’s population was more than 3 million, while Australia’s total population was approximately 27.92 million. This in itself does not mean that it could not become a country, but the size of the population would directly affect the institutional costs it would have to bear after independence.

Functions currently handled by the federal government, including defence, foreign affairs, borders, immigration and some financial and administrative functions, would all need to be established and maintained by Western Australia itself after independence. Therefore, the real question concerning population is not simply “how many people are there?”, but whether this population size could support the institutions and public services required by a fully sovereign country.

(3) Economy

On the other hand, Western Australia does have a very strong economic foundation. According to the latest data from the Western Australian Government, Western Australia’s gross state product was approximately A$461.7 billion in 2024–25, accounting for around 17% of Australia’s economy. In the year to May 2026, Western Australia’s merchandise exports reached A$237.7 billion, accounting for 44.5% of Australia’s total merchandise exports.

But the question is how much of this economic strength could be directly converted into the capabilities of an independent country.

Western Australia’s current exports, businesses, labour market and financial system do not operate within the framework of an independent country. Large-scale resource exports require international trade arrangements, businesses would need to deal with new tax and regulatory systems, while residents would also have to deal with currency, banking, passports, borders and immigration issues that are currently handled uniformly under the federal system. Even if Western Australia retained the Australian dollar, maintained an open border with Australia, or signed a defence cooperation agreement with Australia, these arrangements would all have to be renegotiated rather than naturally continuing after independence.

(4) Identity

Beyond population and the economy, there is another factor that is more difficult to quantify: identity.

Unlike Scotland and Wales, although Western Australia has its own history, geographical environment and regional identity, this does not mean that Western Australians generally see themselves as a nation separate from Australia. Regional identity and Australian identity can coexist. Therefore, separatist demands that have emerged in Western Australia in the past may not necessarily have been based primarily on cultural or national identity. They can also be understood as dissatisfaction with the federal system, central government policies, and the distribution of interests between the states.

In other words, believing that “leaving Australia” would give Western Australia greater autonomy is different from believing that “Western Australia is a nation separate from Australia”. For a genuinely independent country, in addition to having its own government, economy and territory, there must also be sufficient political will for residents to accept a new national identity.

Western Australia today is not a place lacking the conditions for independence, but neither is it a place that could simply leave the Australian Federation after holding a single referendum. The real key would still require fundamental changes to both Australia’s constitutional system and Western Australia’s own political choices.

Three Levels of Government Provide Space Beyond Independence

Australia’s federal system actually provides a relatively important buffer.

The three-level government system has of course not eliminated conflicts between the central government and the regions, but it means that regions do not necessarily have to choose between “completely obeying the central government” and “leaving the country”. State governments already have certain legislative and policy powers. They can formulate state-level policies according to local needs, manage public services, and represent their states in negotiating fiscal and policy arrangements with the federal government.

For Western Australia or other states, this means that even if a state government believes that the distribution of resources under the federal system is unfair, it can still demand reform within the federal framework. Even if it believes that states should have greater autonomy, it can put forward demands for greater state powers. Local interests do not need to first be transformed into demands for independence in order to have political space for expression.

This is one of the important functions of a federal system: it does not require every region to be exactly the same, but within the same country, it allows different regions to retain a certain degree of autonomy.

The Australian Constitution establishes the basic framework of this system by dividing powers between the federal and state governments. The three levels of government then distribute different areas of public responsibility. This arrangement may not prevent all conflicts between the central government and the regions, but it at least provides different levels of political responses.

Therefore, if regional consciousness in an Australian state were to strengthen further in the future, the question would return to the federal system itself: can Australia’s existing federal system continue to accommodate the interests and demands of different regions, allowing regions the space to seek greater autonomy within the federal framework?

Countries Do Not Remain Unchanged, and Institutions Must Respond to Society

From a broader perspective, the UK’s experience is not only about Scotland, Wales or Northern Ireland. It also reflects a more universal question: the relationship between the state and society has never been fixed. Population movements, economic development, generational change, rising levels of education, and the gradual formation of regional identities can all change how society understands power, identity and autonomy. These changes do not necessarily lead directly to independence, but they may cause political arrangements that were once taken for granted to gradually come under renewed scrutiny.

This change does not exist only in the UK or federal countries. For other countries, and even centralised states such as China, how the relationship between the centre and the regions, and between the state and society, should be adjusted is also an issue that needs to be addressed. Central power can be very strong, but maintaining a stable community over the long term depends not only on laws and political institutions, but also on whether institutions can respond to the constantly changing needs of different regions and social groups.

Returning to Australia, the issue facing Western Australia today is still mainly about the distribution of power and interests within the federation, rather than the breakup of the country. But Western Australia already held a secession referendum a century ago, while self-determination debates have re-emerged in the UK today. Looking at these two histories together shows that the relationship between regions and the centre is not fixed. The integrity of a country can be established by laws and institutions, but for a community to remain together over the long term, institutions ultimately need to have the ability to respond to changes in society.
