Parliaments of the Australian states and territories

The parliaments of the Australian states and territories are legislative bodies within the federal framework of the Commonwealth of Australia. All the parliaments are based on the Westminster system, and each is regulated by its own constitution. Queensland and the two territories have unicameral parliaments, with the single house being called the Legislative Assembly. The other states have a bicameral parliament, with a lower house called the Legislative Assembly (New South Wales, Victoria and Western Australia) or House of Assembly (South Australia and Tasmania), and an upper house called the Legislative Council. Unlike in The Federal Parliament, in which Section 44 of The Constitution of Australia prevents persons with dual citizenship to be in Parliament, in State Parliaments there are no laws preventing holders of dual citizenship running for offices. Before the formation of the Commonwealth in 1901, the six Australian colonies were self-governing colonies, with parliaments which had come into existence at various times between 1825, when the New South Wales Legislative Council was created, to 1891, when Western Australia became the last of the colonies to gain full self-government. The colonies ratified the Constitution of Australia, becoming States of the Commonwealth in the new federation, and ceding certain of their legislative powers to the Commonwealth Parliament, but otherwise retaining their self-governing status with their own constitutions and parliaments. The state parliaments were all created by legislation of the British Imperial Parliament, and their original constitutions were contained in Acts of that Parliament; however now the power to amend state constitutions resides with the respective state parliaments, in accordance with its constitution. The Commonwealth Parliament cannot amend a state's constitution. The Australian Capital Territory and the Northern Territory, by contrast, are territories of the Commonwealth, and their parliaments were created by way of legislation of the Commonwealth Parliament.
