Observation

Despite declining trust in the United States and its president, the Australia–US alliance, known as ANZUS, continues to enjoy widespread support among Australians. In 2024, the vast majority of Australians (83%) say the alliance is ‘very important’ or ‘fairly important’ to Australia’s security, steady from last year, and five points below a record high of 87% in 2022.

Australians’ broad support for the alliance has been one of the most resilient features over 20 years of Lowy Institute polling, largely withstanding leadership changes and political swings in the United States. Nevertheless, on average, Australians placed more importance on the alliance during the terms of presidents Obama and Biden than they did during the terms of presidents Bush and Trump.
