who are australia's allies

Australia’s main allies are the United States, New Zealand, key Pacific neighbours, and a set of like‑minded partners in Europe and Asia that cooperate with it through formal treaties and close defence partnerships.

Core security allies

• United States – Australia’s closest security ally, anchored in the ANZUS Treaty (1951), extensive military cooperation, and intelligence sharing through the Five Eyes network.

• New Zealand – Often described by both governments as “natural allies” and “no closer friend”, with deep defence, intelligence, and economic ties across the Tasman.

• United Kingdom – A historic partner linked by the Commonwealth, close defence cooperation, AUKUS security pact participation, and regular joint exercises.

• Papua New Guinea – Recently elevated to a formal Mutual Defence Treaty alliance, Australia’s first new defence alliance in over 70 years and PNG’s first alliance with any country.

Regional partners in the Indo‑Pacific

• Japan – A leading Indo‑Pacific partner with growing defence, intelligence, and technology cooperation, seen as central to balancing China’s power in the region alongside the US and others.

• Philippines – Rapidly rising as one of Australia’s most important regional allies, with expanding defence infrastructure cooperation and shared concern over tensions around Taiwan and the South China Sea.

• Other key Indo‑Pacific partners – India, South Korea, and some ASEAN states (like Singapore and Indonesia) engage in regular exercises, security dialogues, and closer strategic coordination with Australia.

Europe, Canada, and broader like‑minded partners

• European states (e.g., France, Germany, Nordics) – Important partners on trade, climate, and security, often grouped as Australia’s European “allies” in multilateral forums and crisis scenarios.

• Canada – Shares Commonwealth ties, similar foreign‑policy outlooks, and cooperation in multilateral institutions and intelligence frameworks.

• NATO and other partners – While not a NATO member, Australia works closely with NATO and many of its members in Afghanistan‑type missions, sanctions regimes, and joint exercises.

How alliances are changing now

• Australia is tightening links with Indo‑Pacific partners like Japan and the Philippines as uncertainty grows about long‑term US commitments and as regional tensions with China increase.

• Newer treaties like the PNG–Australia Mutual Defence Treaty show a trend toward deeper, more formalised security ties within the Pacific, not just reliance on traditional trans‑Atlantic partners.
