The Australian House of Representatives is elected from 150 single-member districts called Divisions. They are also commonly known as electorates or seats. The British term "constituencies" is rarely used.

Apportionment[edit | edit source]

Divisions are apportioned among the states and territories of Australia in accordance with section 24 of the Australian Constitution and the Electoral Act[1] Generally, apportionment among the states and territories is based on population, with the following provisos:

  • Each original state must have at least 5 Members of Parliament (a provision that gives Tasmania more representation than its population would suggest)
  • The Northern Territory is allocated slightly more representation under recent legislative amendments
  • The Constitution mandates that the House of Representatives should be approximately twice as large as the Senate

Within each state and territory, boundaries must be redrawn in a process known as redistribution at least once every 7 years, or when the state's entitlement to the number of MPs change. Boundaries are drawn by Redistribution Committee, and apportionment within a state is on the basis of the number of enrolled voters rather than total residents.

Within a state or territory, the number of enrolled voters in each Division can not vary by more than 10% from the average across the state, nor can the number of voters vary by more than 3.5% from the average projected enrolment three-and-a-half years into the future.

Naming[edit | edit source]

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.

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 200km north to the south-western suburbs of Sydney over the past century.

The redistribution, creation and abolition of Divisions is the responsibility of the Australian Electoral Commission. Some of the criteria the AEC use when naming new Divisions are listed below:[2]

  • Name divisions after deceased Australians who have rendered outstanding service to their country, with consideration given to former Prime Ministers
  • Retain the original names of Divisions proclaimed at Federation in 1901
  • Avoid geographical place names
  • Where appropriate use Aboriginal names
  • Do not duplicate names of state electoral districts
