Geoscape Geocoded National Address File (G-NAF)

Geoscape G-NAF is the geocoded address database for Australian businesses and governments. It’s the trusted source of geocoded address data for Australia with over 50 million contributed addresses distilled into 15.4 million G-NAF addresses. It is built and maintained by Geoscape Australia using independently examined and validated government data.

From 22 August 2022, Geoscape Australia is making G-NAF available in an additional simplified table format. G-NAF Core makes accessing geocoded addresses easier by utilising less technical effort.

G-NAF Core will be updated on a quarterly basis along with G-NAF.

Further information about contributors to G-NAF is available here.

With more than 15 million Australian physical address record, G-NAF is one of the most ubiquitous and powerful spatial datasets. The records include geocodes, which are latitude and longitude map coordinates. G-NAF does not contain personal information or details relating to individuals.

Updated versions of G-NAF are published on a quarterly basis. Previous versions are available here

Users have the option to download datasets with feature coordinates referencing either GDA94 or GDA2020 datums.

Changes in the February 2024 release

• Nationally, the February 2024 update of G-NAF shows an increase of 42,549 addresses overall (+0.27%). The total number of addresses in G-NAF now stands at 15,608,317 of which 14,779,189 or 94.69% are principal.

• In the February 2024, 850 addresses in Northern Territory and 450 addresses in Queensland have been retired. The addresses were retired following a review because they are considered to be either historical and have been replaced by other addresses or are “infill” addresses.

• The upgrades to the cadastral and property boundaries in Victoria are ongoing and these changes may to affect address geocodes that are relocated more than 1m from their previous geocode as a result of the boundary upgrades.

• From November 2023, Geoscape will be progressively moving product descriptions, guides and reports online to docs.geoscape.com.au. Commencing with the May 2024 release, data packages will no longer include the Documents folder.

Further information on G-NAF, including FAQs on the data, is available here or through Geoscape Australia’s network of partners. They provide a range of commercial products based on G-NAF, including software solutions, consultancy and support.
