The relationship between Australia and the United States is unique in its breadth, depth and length, and is characterised by genuine cultural affinity and a spirit of collaboration.

The two countries’ contemporary relationship encompasses many shared fields of endeavour; including defence and security cooperation, extensive trade and investment links creating jobs for Australians and Americans, cultural exchanges, sporting rivalry, education participation, research and development, and tourism.

Bilateral relations overview

In 2018, Australia and the United States marked a centenary of mateship – a friendship first formed in the trenches of World War I during the Battle of Hamel on 4 July 1918. The two countries maintain a strong relationship, characterised by cultural similarities and robust bilateral arrangements. There are strong formal structures of cooperation between Australia and the United States spanning foreign policy, defence and security, intelligence, development, energy, environment, education, law, trade and investment. The Australia-United States Alliance and the Australia-US Free Trade Agreement (AUSFTA) are central to the bilateral relationship, which also benefits from widespread collaboration across government, academia, and business.

Australia and the United States established diplomatic relations on 8 January 1940. Following the establishment of Australian and US Legations in March and July 1940 respectively, the White House announced the elevation of the Legations to Embassy status on 9 July 1946. Australia's first Ambassador to the United States, Norman J O Makin, presented his credentials to the US Government on 11 September 1946. The first US Ambassador to Australia, Robert Butler, presented his credentials on 25 September 1946.

Defence and security overview

A central pillar of relations between Australia and the United States is the 'ANZUS' Treaty, which was originally an agreement between Australia, New Zealand and the United States. The ANZUS Treaty was signed by the parties in San Francisco in 1951 and entered into force in 1952. The ANZUS Treaty underpins the Australia-United States Alliance. It binds Australia and the United States to consult on mutual threats, and, in accordance with our respective constitutional processes, to act to meet common dangers. Australia invoked the ANZUS Treaty for the first time on 14 September 2001 in response to the terrorist attacks of 11 September.

The Alliance is the foundation of defence and security cooperation between Australia and the United States. It increases Australia's ability to protect itself and its interests by providing access to world-leading defence hardware and technologies, training courses and combined exercises, as well as vital intelligence capabilities. In facilitating such cooperation, the Alliance supports regional engagement, security and stability, underpinning prosperity in the Indo-Pacific. It also enables joint efforts against terrorism and the proliferation of weapons of mass destruction. Both countries are committed to working together to help shape international norms to advance vital shared interests in the sea, air and outer space, as well as to advance important matters related to cybersecurity. Further information about the defence relationship is available on the Australian Department of Defence website.

The Australia-United States Ministerial Consultations (AUSMIN) are held between foreign and defence ministers on a regular basis. AUSMIN was last held on 16 September, 2021 in Washington D.C. Secretary of State Antony Blinken and Secretary of Defense Lloyd Austin hosted then-Minister for Foreign Affairs and then-Minister for Women Marise Payne and Minister for Defence Peter Dutton. Outcomes from AUSMIN 2021 are outlined in the Joint Statement.

In addition to AUSMIN, senior officials regularly meet with US counterparts on a broad range of issues including political-military meetings and military-military talks.
