The Australian Antarctic Territory (AAT) is a part of East Antarctica claimed by Australia as an external territory. It is administered by the Australian Antarctic Division, an agency of the federal Department of Climate Change, Energy, the Environment and Water. The territory's history dates to a claim on Enderby Land made by the United Kingdom in 1841, which was subsequently expanded and eventually transferred to Australia in 1933.

The territory's dual name (official since the islands' incorporation into Australia in 1955) reflects that the islands have historically been known as either the Cocos Islands or the Keeling Islands
