The Australian Defence Force (ADF) is the military organisation responsible for the defence of the Commonwealth of Australia and its national interests. It has three branches: the Royal Australian Navy (RAN), Australian Army and the Royal Australian Air Force (RAAF). The ADF has a strength of just over 89,000 personnel and is supported by the Department of Defence and several other civilian agencies.
The retirement of the aircraft carrier HMAS Melbourne without replacement in 1982 marked a shift away from the policy of "forward defence".

Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. Australia is the largest country by area in Oceania and the world's sixth-largest country. Australia is the oldest, flattest, and driest inhabited continent, with the least fertile soils. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, with deserts in the centre, tropical rainforests in the north-east, tropical savannas in the north, and mountain ranges in the south-east.
