Australia–Canada relations

Australia and Canada have a longstanding relationship fostered by both countries' shared history and culture as well as the links between residents of the countries. The two countries are former British Dominions and have a common head of state in King Charles III (legally, the King is equally and separately the sovereign of both countries, as King of Australia and King of Canada). Both countries share the Westminster parliamentary system of government; and both countries are members of the Asia-Pacific Economic Cooperation, Cairns Group, Commonwealth of Nations, Comprehensive and Progressive Agreement for Trans-Pacific Partnership, Five Eyes, OECD and the United Nations.
