Australia and the United States have announced a wide-ranging set of defence, security and economic initiatives following the 2025 Australia-U.S. Ministerial Consultations (AUSMIN) held in Washington, D.C. on 8 December. The meeting, marking 40 years of AUSMIN, brought together U.S. Secretary of State Marco Rubio, Secretary of War Pete Hegseth, Australian Foreign Minister Penny Wong and Defence Minister Richard Marles. The consultations followed the October 2025 leaders’ meeting between President Donald J. Trump and Prime Minister Anthony Albanese.
The Principals committed to expanded cooperation to support a “free and open Indo-Pacific,” including measures to strengthen regional stability, promote economic resilience and coordinate critical infrastructure investment across Southeast Asia and the Pacific. This includes Australian involvement in the Luzon Economic Corridor alongside the United States, the Philippines and Japan, and continued telecommunications and economic development cooperation with Papua New Guinea, including at Lae Port. Both countries welcomed the completion of the Vaka Submarine Cable to Tuvalu, jointly funded with regional partners.
The two countries also plan to increase joint work on air and missile defence data-sharing with Japan, and will continue Maritime Cooperative Activities in the South China Sea with the Philippines. A new bilateral interagency working group will focus on combating online scam operations, and the countries reaffirmed their cooperation on financial intelligence through a renewed AUSTRAC–FinCEN agreement. The United States and Australia will invest around USD $10 million and AUD $10 million respectively in cyber capacity building in Southeast Asia and the Pacific, including another Pacific Cyber Week.
Defence cooperation featured heavily in the talks, with both nations reaffirming the importance of the alliance ahead of the 75th anniversary of the ANZUS Treaty in 2026. The Principals highlighted ongoing force posture initiatives, including infrastructure works to support rotations of U.S. aircraft through RAAF Bases Tindal, Darwin and Amberley, expanded capacity for the Marine Rotational Force–Darwin and new Northern and Southern logistics nodes. The United States will establish an Oversight and Support Group in Australia to coordinate its force posture presence.
Progress under AUKUS was also emphasised, including Australia’s scheduled contribution of a further USD $1 billion toward expanding the U.S. submarine industrial base, bringing its total investment so far to USD $2 billion. The Principals reaffirmed plans for Submarine Rotational Force-West to begin as early as 2027, alongside maintenance of U.S. submarines at HMAS Stirling.
The two nations endorsed a shared pathway for cooperation in the Guided Weapons and Explosive Ordnance (GWEO) enterprise, covering co-production of hypersonic cruise missiles, sustainment of AIM-9X and AMRAAM missiles, and future work on maritime strike and interceptor capabilities. They also supported broader defence industrial integration through export-control exemptions and streamlined third-party transfer arrangements.
On economic security, the Principals highlighted swift implementation of the bilateral Critical Minerals Framework. They noted progress on gallium production in Australia through Alcoa beginning in 2026, and welcomed coordinated Letters of Support totalling USD $600 million from Export Finance Australia and the U.S. EXIM Bank for Tronox’s planned expansion of rare earth and mineral projects. Both sides will explore reserve mechanisms and long-term offtake arrangements to strengthen supply chains for national security purposes.
From 15 December 2025, all Australian citizens will become eligible for the U.S. Global Entry program. The two countries are also considering a Customs Mutual Assistance Agreement to improve cooperation on detecting and disrupting customs law violations.
