ANZUS Treaty marks 75 years of Pacific security cooperation

The ANZUS security treaty, originally signed in 1951 between Australia, New Zealand, and the United States, has reached its 75th anniversary. While the treaty's focus has shifted over decades—notably after the US suspended obligations to New Zealand in 1986 due to its anti-nuclear policy—the alliance is seeing a resurgence in regional importance.

New Zealand Prime Minister Christopher Luxon and Australian Prime Minister Anthony Albanese have worked to strengthen trans-Tasman ties. This includes the establishment of the annual meeting of Australian and New Zealand foreign and defence ministers (ANZMIN) and the inaugural Australia–New Zealand leaders’ meeting in August 2024. These mechanisms aim to deepen military cooperation and security support in the Pacific to deter regional threats.

Security experts note that while the US alliance remains the “bedrock” of Australian security, the nation should not assume the relationship will remain unchanged. As strategic circumstances in the Pacific evolve, discussions continue regarding the balance between alliance benefits, such as the AUKUS pact, and the potential risks to national independence.
