Electorates of the Australian House of Representatives

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.

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.

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.
