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 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.
