Australia and Japan decline naval deployment in Strait of Hormuz coalition

Australia and Japan have ruled out sending warships to the Strait of Hormuz despite calls from United States President Donald Trump for allied nations to help secure the vital maritime route amid rising tensions with Iran.

Canberra confirmed Monday that it will not deploy naval vessels to the strait, even as Washington seeks to form a multinational coalition to protect shipping through the strategic corridor that carries a significant share of the world’s oil supplies.

Australian Transport Minister Catherine King said the government had already clarified its response to allied requests and would maintain a defensive contribution rather than a naval presence. Speaking to ABC Radio, she said Australia’s involvement focuses on protecting its nationals in the region and supporting partners through defensive measures rather than sending ships into the strait.

King noted that Australia had already deployed aircraft to the United Arab Emirates to assist with regional defense operations. The government sent an E-7A Wedgetail surveillance aircraft, about 85 military personnel and air-to-air missiles following discussions between Prime Minister Anthony Albanese and UAE President Mohammed bin Zayed Al Nahyan.

Deputy Foreign Affairs Minister Matt Thistlethwaite reiterated that Australia is not directly involved in the conflict but will continue efforts to safeguard Australians in the region.

Opposition defense spokesman James Paterson also questioned whether Australia has the naval capacity to participate in such an operation. He referred to a similar situation in 2023 during the Red Sea crisis when Canberra declined a request from the Biden administration to deploy ships because available vessels lacked adequate protection against drone and missile attacks.

Japan has taken a similarly cautious position. Prime Minister Sanae Takaichi told parliament in Tokyo that no decision has been made regarding the dispatch of escort vessels to the Strait of Hormuz.

Japan’s pacifist constitution imposes strict limits on overseas military operations. Takayuki Kobayashi, policy chief of the ruling Liberal Democratic Party, said any such deployment would face an extremely high threshold under existing legal constraints.

Takaichi is scheduled to travel to Washington this week for talks with Trump, where she plans to advocate for rapid de-escalation of tensions in the region.

Trump had earlier urged major economies including China, France, Japan, South Korea and the United Kingdom to send warships to ensure the strait remains open and secure. He framed the mission as a shared responsibility for countries that rely heavily on energy supplies from the Middle East.

The Strait of Hormuz handles roughly one fifth of global oil shipments. Commercial tanker traffic has largely halted since United States and Israeli strikes against Iran began on February 28.

So far, Britain is the only country to signal it is considering possible measures. British officials have said they are discussing a range of options with allies to help safeguard navigation in the area.

The cautious responses from Australia and Japan highlight the challenges facing Washington as it seeks to build an international naval coalition, even among close security partners that depend heavily on stable energy flows from the Gulf.
