Foreign relations and the military

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. Australia is a member of the Commonwealth of Nations, in which the Commonwealth Heads of Government meetings provide the main forum for co-operation. Australia has energetically pursued the cause of international trade liberalisation. Australia led the formation of the Cairns Group and APEC, and is a member of the OECD and the WTO. Australia has pursued several major bilateral free trade agreements, most recently the Australia-United States Free Trade Agreement and Closer Economic Relations with New Zealand. Australia is a founding member of the United Nations, and maintains an international aid program under which some 60 countries receive assistance. The 2005–06 budget provides A$2.5 bn for development assistance; as a percentage of GDP, this contribution is less than that of the UN Millennium Development Goals.
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), numbering about 51,000. All branches of the ADF have been involved in UN and regional peacekeeping (most recently in East Timor, the Solomon Islands and Sudan), disaster relief, and armed conflict, including the 2003 invasion of Iraq. The government appoints the Chief of the Defence Force from one of the armed services; the current Chief of the Defence Force is Air Chief Marshal Angus Houston. In the 2006–07 budget, defence spending is A$22 bn.
