Defence is involved in a number of security and surveillance operations around the world, encompassing South-East and Central Asia, the Western Pacific, the Middle East, Europe and Africa. Defence is also involved in a number of non-military operations, including operations against illegal immigration and smuggling and foreign fishing incursions into Australia’s sub-Antarctic exclusive economic zone. Of continuing importance is the provision of Australian forces in support of the United Nations Transitional Administration in East Timor (Operation Tanager), where Defence has committed approximately 1,600 personnel. Details of current Australian Defence Force operations are contained in Defence's statutory reporting documents, which can be found at http://www.defence.gov.au/budget.
