In 2026, 73% say Australia’s alliance relationship with the United States was important to its security.

Support for Australia’s alliance with the United States, known as ANZUS, has been the most resilient finding in the 22-year history of the Lowy Institute Poll. This year, support for the alliance is again strong, with nearly three-quarters of Australians (73%) saying it is either ‘very important’ or ‘fairly important’ to Australia’s security. This represents a seven-point drop from last year’s Poll and a ten-point drop from 2024, marking the sharpest sustained fall in support for the alliance in the history of the Poll. However, this year’s result remains ten points higher than the 2007 low, which was recorded during the Iraq War.
