Australia’s Defence Minister Richard Marles is set to meet with U.S. Defense Secretary Pete Hegseth and Japanese Defence Minister Gen Nakatani at the Shangri-La Dialogue in Singapore from May 30 to June 1. This marks the first trilateral meeting since Australia's recent elections and the Trump administration’s return to office.
The annual security forum brings together global defense ministers, diplomats, and military officials to discuss pressing regional challenges. Marles' participation also marks his first overseas visit since the Labor government secured a stronger mandate earlier this month.
The three allies last met in Darwin in November, agreeing to enhance joint military drills, intelligence-sharing, and surveillance. The renewed dialogue will focus on reinforcing these commitments, particularly in light of rising tensions in the Indo-Pacific.
In February, Marles visited Washington to discuss the AUKUS submarine partnership. Australia is expected to contribute $2 billion this year to support the U.S. submarine industrial base. While Washington pushes for Australia to raise defense spending to 3% of GDP, Prime Minister Anthony Albanese recently committed to a 2.4% target, emphasizing investments in regional capability and partnerships.
Analysts, including Euan Graham of the Australian Strategic Policy Institute, caution that Australia must assure partners of its military readiness amid delays in AUKUS-related assets. Nuclear-powered submarines from the UK and Australia are projected for 2040, and the purchase of U.S.-made Virginia-class subs by 2032 faces uncertainties due to production issues.
Australia maintains that the AUKUS deal adheres to nuclear non-proliferation norms, with submarines being conventionally armed. However, experts stress that conventional and nuclear deterrence must be strategically aligned to maintain regional credibility.
Marles will address regional threats during his speech at the forum on Saturday.
