6 October 1903

The High Court of Australia sits for the first time.


The High Court of Australia is the supreme court in the Australian court hierarchy and the final court of appeal in Australia. It has both original and appellate jurisdiction, the power of judicial review over laws passed by the Parliament of Australia and the parliaments of the States, and the ability to interpret the Constitution of Australia thereby powerfully shaping the development of federalism in Australia.

The High Court is mandated by Constitution section 71, which vests in it the judicial power of the Commonwealth of Australia. The Court was constituted by, and its first members were appointed under, the Judiciary Act 1903. It now operates under Constitution sections 71 to 75, the Judiciary Act, and the High Court of Australia Act 1979. It is composed of seven Justices: the Chief Justice of Australia, currently Susan Kiefel, and six other Justices. They are appointed by the Governor-General of Australia, on the advice of the federal government, and under the constitution must retire at age 70.

Since 1979, The High Court has been located in Canberra, Australian Capital Territory. The majority of its sittings are held in the High Court building, situated in the Parliamentary Triangle, overlooking Lake Burley Griffin. With an increasing utilisation of video links, sittings are also commonly held in the state capitals.
