Australia has entered early-stage discussions with the United States over a new proposal to reopen the Strait of Hormuz. The initiative, put forward by the Trump administration, seeks to establish an international coalition known as the Maritime Freedom Construct (MFC), aimed at restoring freedom of navigation through this critical waterway.
Australian Foreign Minister Penny Wong confirmed on Thursday that the US had briefed Australia on the plan. She said the government is currently “considering a range of options” in consultation with allies including the United Kingdom, France and the United States. Wong stressed that Australia has already provided defence and diplomatic support to the Middle East region, but no decision has been made on further involvement. Government sources noted that discussions remain at a preliminary stage.
According to a US State Department cable, the MFC would be jointly led by the State Department and the Pentagon. Its proposed activities include providing real-time information, safety guidance and coordination to protect commercial shipping. A diplomatic operations hub in Washington would also coordinate economic and diplomatic measures against Iran in response to disruptions to maritime security. Participation could take various forms, including diplomacy, intelligence sharing, sanctions enforcement, or military deployment.
Australia has previously downplayed the likelihood of involvement in reopening the strait, emphasising instead its contribution through deploying E-7 Wedgetail surveillance aircraft to the United Arab Emirates. The government has also stated it did not receive any formal request from the US, despite criticism from President Trump over perceived inaction.
Shadow Foreign Minister Ted O’Brien said the proposal should be carefully considered, arguing that ensuring the Strait of Hormuz remains open and secure is in Australia’s national interest.
Commentary:
The Strait of Hormuz carries around one-third of global seaborne oil trade, making its stability crucial to global energy prices and economic order. For Australia, which relies heavily on imported energy, maintaining freedom of navigation is clearly in its national interest.
However, the key question is how Australia chooses to engage. Closer alignment with the United States risks being seen as taking sides in Middle East tensions, potentially undermining Australia’s longstanding emphasis on diplomatic balance and multilateralism. At the same time, sustained pressure and criticism from Donald Trump place Australia under increasing expectation to demonstrate alliance solidarity.
The challenge ahead is whether Australia can limit its role to diplomatic coordination and institutional cooperation, rather than direct military involvement, striking a careful balance between safeguarding maritime security and preserving strategic autonomy.
