Foreign Relation of Australia.

Over recent decades, Australia's foreign relations have been driven by a close association with the United States through the ANZUS pact, and by a desire to develop relationships with Asia and the Pacific, particularly through ASEAN and the Pacific Islands Forum. In 2005 Australia secured an inaugural seat at the East Asia Summit following its accession to the Treaty of Amity and Cooperation in Southeast Asia. Australia is a member of the Commonwealth of Nations, in which the Commonwealth Heads of Government meetings provide the main forum for cooperation.

Australia has pursued the cause of international trade liberalisation.It led the formation of the Cairns Group and Asia-Pacific Economic Cooperation. Australia is a member of the Organisation for Economic Co-operation and Development and the World Trade Organization, and has pursued several major bilateral free trade agreements, most recently the Australia – United States Free Trade Agreement and Closer Economic Relations with New Zealand. As of 2010, Australia is negotiating a free trade agreement with Japan, with whom Australia has close economic ties as a trusted partner in the Asia-Pacific region.

Along with New Zealand, the United Kingdom, Malaysia, and Singapore, Australia is party to the Five Power Defence Arrangements, a regional defence agreement. A founding member country of the United Nations, Australia is strongly committed to multilateralism, and maintains an international aid program under which some 60 countries receive assistance. The 2005–06 budget provides $2.5 billion for development assistance; as a percentage of GDP, this contribution is less than that recommended in the UN Millennium Development Goals. Australia ranks seventh overall in the Center for Global Development's 2008 Commitment to Development Index.

Australia's armed forces—the Australian Defence Force (ADF)—comprise the Royal Australian Navy (RAN), the Australian Army, and the Royal Australian Air Force (RAAF), in total numbering 80,561 personnel (including 55,068 regulars and 25,493 reservists). The titular role of Commander-in-Chief is vested in the Governor-General, who appoints a Chief of the Defence Force from one of the armed services on the advice of the government.Day-to-day force operations are under the command of the Chief, while broader administration and the formulation of defence policy is undertaken by the Minister and Department of Defence.

In the 2010–11 budget, defence spending was $25.7 billion, representing the 14th largest defence budget in the world but accounting for only 1.2% of global military spending. Australia has been been involved in UN and regional peacekeeping, disaster relief, and armed conflict; it currently has deployed approximately 3,330 defence force personnel in varying capacities to 12 overseas operations in areas including East Timor, Solomon Islands and Afghanistan.
