Electorates of the Australian states and territories

A State Electoral District is an electorate within the Lower House or Legislative Assembly of Australian states and territories. Most state electoral districts (except the Australian Capital Territory and Tasmania, which have multi-member electorates using a proportional voting method) send a single member to a state or territory's parliament using the preferential method of voting. The area of a state electoral district is dependent upon the Electoral Acts in the various states and vary in area between them. At present, there are 409 state electoral districts in Australia.

State electoral districts do not apply to the Upper House, or Legislative Council, in those states that have one (New South Wales, South Australia, Tasmania, Victoria and Western Australia). In New South Wales and South Australia, MLCs represent the entire state, in Tasmania they represent single-member districts, and in Victoria and Western Australia they represent a region formed by grouping electoral districts together.
