The lower houses of the parliaments of the states and territories of Australia are divided into electoral districts. Most 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.
