Geoscape G-NAF is Australia’s authoritative, geocoded address file. It is built and maintained by Geoscape Australia using authoritative government data. Further information about contributors to G-NAF is available here.
G-NAF is one of the most ubiquitous and powerful spatial datasets. It contains more than 15 million Australian physical address records. 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.
Users have the option to download datasets with feature coordinates referencing either GDA94 or GDA2020 datums.
Changes in the May 2025 release
-
Nationally, the May 2025 update of G-NAF shows an overall increase of 47,194 addresses (0.30%). The total number of addresses in G-NAF now stands at 15,753,927 of which 14,909,770 or 94.64% are principal.
-
At some locations, there are unit-numbered addresses that appear to be duplicate addresses. Geoscape is working to identify these locations and include these addresses as separate addresses in G-NAF. To facilitate this process, some secondary addresses have had the word RETAIL added to their building names. In the first instance, this process is being progressively rolled out to identified locations, but it is expected that the requirement for this will become ongoing.
-
There is one new locality in G-NAF: Keswick Island, QLD.
-
The source data used for generating G-NAF STREET_LOCALITY_POINT data in New South Wales has an updated datum and changed from GDA94 to GDA2020. This has resulted in updates to the STREET_LOCALITY_POINT geometry for approximately 91,000 records, however, more than 95% of these have moved less than a metre.
-
Geoscape has moved product descriptions, guides and reports online to https://docs.geoscape.com.au.
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.
Note: On 1 October 2020, PSMA Australia Limited began trading as Geoscape Australia.
