Australia’s Defence Minister Richard Marles will travel to Japan on Saturday for talks with his counterpart Koizumi Shinjiro, with both sides eager to accelerate defence cooperation under Japan’s new Prime Minister Sanae Takaichi. Australian officials said the visit reflects a desire to engage early with Tokyo’s new leadership and reinforce what they describe as a rapidly strengthening “shared vision” for regional security. Marles said the bilateral relationship is expanding “from strength to strength,” driven by mutual strategic priorities and rising geopolitical uncertainty.
Regional Flashpoints Shape the Agenda
The visit comes during one of the most strained periods in Japan–China relations in years. Takaichi recently suggested in parliament that a hypothetical Chinese attack on Taiwan could trigger a Japanese military response, prompting fierce criticism from Beijing. Australia, which has been tightening its own security posture, views Japan as a central partner in responding to China’s growing military reach across the Indo-Pacific. The two sides are expected to discuss maritime security, regional deterrence and ways to coordinate operational planning.
Deepening Defence Cooperation
Defence-industrial ties between the two countries are already expanding. In August, Australia awarded a A$10 billion ($6.5 billion) contract to Mitsubishi Heavy Industries to build warships Japan’s most significant export since lifting its postwar ban on military sales in 2014. Australia intends to deploy the Mogami-class frigates to safeguard vital maritime routes and reinforce defences in the Indian and Pacific Oceans, where Chinese naval operations continue to intensify.
Fututre Outlook: AUKUS and Broader Alliance Planning
After his Japan trip, Marles will travel to Washington for meetings with U.S. and British defence officials to review progress under the AUKUS submarine pact. The Pentagon has completed its latest assessment of the programme and identified areas to strengthen the plan to supply Australia with nuclear-powered submarines. Canberra is also undergoing an internal defence overhaul, aiming to accelerate naval shipbuilding in response to the region’s rapidly evolving security environment.
