The Geocoded National Address File (G-NAF) contains all physical addresses in Australia. It is a composite of information supplied by each state and territory government addressing agency, as well as some Commonwealth government agencies. The address data includes the state, suburb, street, number and coordinate reference (or “geocode”) for street addresses in Australia. More information about G-NAF is available on the Geoscape web site.

The Australian Government signed a contract extension with Geoscape in July 2023 and committed $42.4 million to ensure G-NAF data remains freely available until mid-2029 (more info here). The freely available G-NAF is updated every three months.
