G-NAF is Australia’s most trusted and comprehensive geocoded address dataset. This award-winning dataset combines over 30 million addresses from 10 address custodians to deliverer a national database of more than 13 million geocoded¬†physical addresses.


G-NAF makes it possible to verify a physical address in Australia and locate its position.

Every address within G-NAF is compared between the contributors (each of the state and territory governments, Australia Post and the Australian Electoral Commission) and matched against authoritative spatial datasets to ensure that there is a legal land parcel, road or locality to verify the existence and quality of the address.

G-NAF includes:

  • Location information, through the provision of a geocode that places each address at either the land parcel, the street or locality particular to each address
  • Confidence level, providing an insight into whether one, two or three of the authoritative contributors have provided the address
  • An extensive range of alias address information, covering information such as duplicate addresses, commonly known names and vanity addresses
  • ABS Mesh Block codes for each address, simplifying analysis against ABS statistical information and similarly aligned data.
