The Gazetteer of Australia is a register of the location and spelling of geographical names across Australia. It is compiled by the Intergovernmental Committee on Surveying and Mapping (ICSM) and derived from state, territory, and Australian government agencies.
As of December 2004 there are 315500 named places in Australia. These are searchable in an online database hosted by Geoscience Australia and the entire dataset can be purchased from the same organisation.
