In mathematics, a Young tableau (; plural: tableaux) is a combinatorial object useful in representation theory and Schubert calculus. It provides a convenient way to describe the group representations of the symmetric and general linear groups and to study their properties. Young tableaux were introduced by Alfred Young, a mathematician at Cambridge University, in 1900. They were then applied to the study of the symmetric group by Georg Frobenius in 1903. Their theory was further developed by many mathematicians, including Percy MacMahon, W. V. D. Hodge, G. de B. Robinson, Gian-Carlo Rota, Alain Lascoux, Marcel-Paul Schützenberger and Richard P. Stanley.

Each state and major mainland territory has its own parliament — unicameral in the Northern Territory, the ACT and Queensland, and bicameral in the other states. The states are sovereign entities, although subject to certain powers of the Commonwealth as defined by the Constitution. The lower houses are known as the Legislative Assembly (the House of Assembly in South Australia and Tasmania); the upper houses are known as the Legislative Council. The head of the government in each state is the Premier and in each territory the Chief Minister. The Queen is represented in each state by a governor; and in the Northern Territory, the Administrator. In the Commonwealth, the Queen's representative is the Governor-General.The Commonwealth Parliament also directly administers the following external territories: Ashmore and Cartier Islands; Australian Antarctic Territory; Christmas Island; Cocos (Keeling) Islands; Coral Sea Islands; Heard Island and McDonald Islands; and 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 administered by Tasmania, and Lord Howe Island by New South Wales.
