The Composite Gazetteer of Australia (CGA) is the national repository of Australia’s approved place names, drawing together data from each state, territory, and relevant Commonwealth authorities. It is the place names point database that is used by the CGA web application, https://placenames.fsdf.org.au, to deliver jurisdictional place name information as one collection. The CGA is collaborative effort - every Australian state and mainland territory provides data from its official register of geographic names, administered by its naming authority (e.g. VICNAMES in Victoria, the NSW Geographical Names Board, etc). In addition, the Australian Hydrographic Office (AHO) contributes offshore undersea feature names, and the Australian Antarctic Division (AAD) provides Antarctic place names. All data provided for the CGA is managed by respective naming authorities. Over decades, it has evolved through collaborative governance and technical innovation. The effort is coordinated under the Intergovernmental Committee on Surveying and Mapping (ICSM), through its Australia and New Zealand Place Names Working Group (ANZPNWG), formerly Permanent Committee on Place Names (PCPN) or its predecessor, Committee for Geographical Names in Australasia (CGNA). The database is also available to search and direct download from the web application, currently https://placenames.fsdf.org.au.The spatial accuracy of the place names points varies between jurisdictions and cannot be relied upon for navigation, precise positioning, or safety-of-life applications. Any quality issues with individual data points should be referred to the relevant naming authority.
