APEC Australia 2007 was a series of political meetings held around Australia between the 21 member economies of the Asia-Pacific Economic Cooperation during 2007. Various meetings were held across Australia from January to August 2007, with the event cumulating in Leaders Week, where the heads of government of each member economy attended Sydney, New South Wales from 2 to 9 September 2007.

As the role of APEC host economy rotates between member economies, Australia had been the designated host for 2007 for a number of years. In August 2004, the Department of the Prime Minister and Cabinet established the APEC 2007 Taskforce to allocate a host city within Australia and to organise the event. On 9 February 2005, Prime Minister John Howard announced that Sydney, New South Wales would host the ultimate Leaders Week event. It was also announced that various preliminary meetings would be held in all Australian state and territory capital cities.

Overall security planning was overseen by the Protective Security Coordination Centre (PSCC) of the National Security and Criminal Justice Group from the Attorney-General's Department, through the establishment of an APEC 2007 Security Branch (ASB). The PSCC performed a similar role for the 2006 Commonwealth Games held in Melbourne.

Australia ( /əˈstreɪljə/), officially the Commonwealth of Australia, is a country in the Southern Hemisphere comprising the mainland of the Australian continent as well as the island of Tasmania and numerous smaller islands in the Indian and Pacific Oceans. It is the world's sixth-largest country by total area. Neighbouring countries include Indonesia, East Timor and Papua New Guinea to the north; the Solomon Islands, Vanuatu and New Caledonia to the north-east; and New Zealand to the south-east.

For at least 40,000 years before European settlement in the late 18th century, Australia was inhabited by indigenous Australians, who belonged to one or more of roughly 250 language groups. After discovery by Dutch explorers in 1606, Australia's eastern half was claimed by Great Britain in 1770 and settled through penal transportation to the colony of New South Wales from 26 January 1788. The population grew steadily in subsequent decades; the continent was explored and an additional five self-governing Crown Colonies were established.
