The resources minister, Madeleine King, says Australian industry will be reliant on gas for the “foreseeable future”, and that the national gas reservation scheme will push down power prices.

But she did not put a price tag on the cost of gas under the proposal – as the former opposition leader Peter Dutton once did – nor predict when households and businesses would start to see that financial relief.

In an address to the National Press Club on Wednesday, King said keeping gas affordable for households and businesses was a critical part of the scheme’s primary focus. She expected the scheme would “push down” gas prices without crashing the market. The national gas reservation scheme will force gas companies to set aside 20% of exports for domestic use, and is expected to come into effect from January 2028. It will give the Australian Energy Regulator the power to force companies to meet a target of 110% of projected demand each year. It will also limit ministerial discretion and replace the Turnbull-era domestic gas security mechanism.

The minister said gas was central to heating homes, keeping manufacturing industries running, processing critical minerals and rare earths domestically, and supporting the rollout of renewables. When asked whether she had a timeline to phase out Australia’s reliance on gas, King said it would continue to play an important role unless a viable replacement was found.

The shadow resources minister, Susan McDonald, said “numerous questions” remained over the design and viability of the scheme. McDonald didn’t identify particular concerns but said the bill’s greatest risk was the “capitulation of Labor to pressure from the Greens political party and noisy activists”.

Labor’s bid to cut the private health insurance rebate for over-65s has been blocked in parliament, with the Greens insisting they will withhold support unless pensioners receive a carve-out from the new rules.

The proposed changes, which would take effect from April 2027, would save the federal budget $3bn. It marks another defeat for a key cost-saving measure after the government was forced to back down on its plan to cap allied health payments for veterans which would have saved $748m over three years. People who are 65 or over currently receive a larger rebate on their premium, with the rebate higher for those 70 and over.

The Greens, Coalition and crossbench senators teamed up in the Senate on Wednesday to block Labor’s bill. In a rare move, the bill was discharged from the upper house, meaning it will need to be reintroduced if Labor tries to push ahead.

The Greens leader, David Shoebridge, said the party would only offer its support for the changes if the government excluded pensioners. Almost 80,000 older Australians are expected to ditch their private health cover by 2028-29 as a result of the Albanese government’s proposal, according to health department modelling released under freedom of information laws.

The chief executive of the Council on the Ageing Australia, Patricia Sparrow, also rejected the planned savings being linked to aged care funding commitments. She explained that older Australians shouldn’t have to choose between protecting their health and paying for everyday essentials, nor should they be asked to choose between affordable healthcare and a properly funded aged care system.

Australia’s online safety regulator eSafety says it does not have the powers to “proactively prevent” the live stream of a firing squad execution in the United States from being shown in Australia, but argues platforms have a responsibility to protect users from harmful content.

Last week, US Defense Secretary Pete Hegseth said the execution of Nidal Malik Hasan, convicted of killing 13 people at a military base in Texas in 2009, would be available for the public to watch. Across the political divide in Canberra there has been widespread concern about Australians seeing the December 3 live stream.

The federal government said Australians “rightly expect” the content would not appear on their screens, and platforms have a responsibility to meet those expectations. Media Lecturer at Swinburne University Dr Belinda Barnet believed the most the eSafety commissioner could do was issue take down notices, like was done in the case of a Sydney church stabbing in 2024.

“While eSafety does not have powers to proactively prevent a live stream from occurring online, online services have responsibilities under Australia’s online safety regulatory framework to protect users from harmful material,” a spokesperson said. Experts agreed eSafety’s power was more geared towards being able to take down content rather than pre-emptively blocking it.
