Federal Electoral Divisions (March 2025)

Abstract The Parliament consists of the King (represented by the Governor-General) and two Houses (the Senate and the House of Representatives). The House of Representatives reviews, debates and votes on proposed laws. Each member elected to the House of Representatives represents a single electoral division, also known as an electorate, which does not cross state or territory borders. Each of the six states, the Australian Capital Territory and Northern Territory gains representation in the House of Representatives in proportion to their population, and there are a similar number of electors in each electoral division within a given state or territory. The names and boundaries of electoral divisions within a state or territory are reviewed periodically and may be adjusted. This process is known as a redistribution of federal electoral divisions. The Federal Electoral Divisions dataset contains the names and geographic boundaries of the federal electoral divisions in Australia. The Senate is also often referred to as the ‘state’s house’ or the ‘house of review’. The Senate"s law-making powers are equal to those of the House of Representatives except that it cannot introduce or amend proposed laws that authorise expenditure for the ordinary annual services of the government or that impose taxation. Those elected to the Senate are called ‘Senator’. Senators represent all of one of the six states, the Australian Capital Territory or the Northern Territory. There are 12 senators for each of the six states and there are two senators each for the Australian Capital Territory and the Northern Territory. These boundaries are provided in vector format with Electoral Divisions represented by polygons. Redistributions of federal electoral divisions are conducted of individual states or territories. The electoral divisions in this data have been used at general elections conducted since the date on which the redistribution was determined: NSW - electoral divisions reflect changes made as a result of the redistribution of New South Wales determined on 10 October 2024.
