Important legal instruments of the High Court include the Judiciary Act 1903, and the High Court of Australia Act 1979.

Its bench is composed of seven justices, including a Chief Justice, currently Susan Kiefel . Justices of the High Court are appointed on the advice of the Prime Minister by the Governor-General and are appointed permanently until their mandatory retirement at age 70.
