The Commonwealth Parliament also directly administers the external territories of Ashmore and Cartier Islands, Christmas Island, the Cocos (Keeling) Islands, the Coral Sea Islands, Heard Island and McDonald Islands, and the claimed region of Australian Antarctic Territory, as well as the internal Jervis Bay Territory, a naval base and sea port for the national capital in land that was formerly part of New South Wales. The external territory of Norfolk Island previously exercised considerable autonomy under the "Norfolk Island Act 1979" through its own legislative assembly and an Administrator to represent the Queen. In 2015, the Commonwealth Parliament abolished self-government, integrating Norfolk Island into the Australian tax and welfare systems and replacing its legislative assembly with a council. Macquarie Island is part of Tasmania, and Lord Howe Island of New South Wales.
