held on 21 May 2022. Within each state and territory, electoral boundaries are redrawn from time to time. This takes place at least once every 7 years, or when the state's entitlement to the number of members of the House of Representatives changes. Boundaries are drawn by a Redistribution Committee, and redistributions within a state are on the basis of the number of enrolled voters, rather than total residents or "population". The number of enrolled voters in each division cannot vary by more than 10% from the average across a state or territory, nor can the number of voters vary by more than 3.5% from the average projected enrolment 3.5 years into the future. However, due to various reasons, larger seats like Cowper in New South Wales contain 80% more electors than that of smaller seats like Solomon in the Northern Territory. In 2018, seats in Victoria, Tasmania and South Australia were also abolished, in order to make way for seats in similar locations but with different names. At the 2022 Australian federal election, based on the 2021 apportionment, there were 151 divisions: 47 in New South Wales, 39 in Victoria, 30 in Queensland, 15 in Western Australia, 10 in South Australia, 5 in Tasmania, 3 in the ACT and 2 in Northern Territory. Naming The divisions of the House of Representatives are unusual in that many of them are not named after geographical features or numbered, as is the case in most other legislatures around the world. Most divisions are named in honour of prominent historical people, such as former politicians (often Prime Ministers), explorers, artists and engineers. There is also a preference for retaining names used since Federation. In some cases where a division is named after a geographical locality, the connection to that locality is sometimes tenuous. For instance, the Division of Werriwa, created in 1901, was named after the Aboriginal word for Lake George in the Canberra region. However, Werriwa has not contained Lake George for many decades, and has steadily moved some 200 km north to the south-western suburbs of Sydney over the past century.
