<P> 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 . </P> <P> The High Court is mandated by section 71 of the Constitution, 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 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 . </P> <P> Since 1979, The High Court has been located in Canberra, Australian Capital Territory .

The High Court is the court of final appeal with the ability to interpret the common law for the whole of Australia, not just the state or territory in which the matter arose . The High Court's broad jurisdiction is similar to that of the Supreme Court of Canada and unlike the Supreme Court of the United States which has a more limited jurisdiction . As such, the court is able to develop the common law consistently across all the states and territories . This role, alongside its role in constitutional interpretation, is one of the court's most significant . As Sir Owen Dixon said on his swearing in as Chief Justice of Australia: </P>
