The Australian Antarctic Territory is created.

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. It is the largest sector of Antarctica by area claimed by any country. Australia is an original signatory to the Antarctic Treaty of 1959. Under Article IV, all territorial claims are held in abeyance. Only four other countries accept Australia's claim to sovereignty, being New Zealand, the United Kingdom, France, and Norway, all of which have territorial claims in Antarctica and mutually accept each other’s claims.
