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 15.9 million G-NAF addresses. It is built and maintained by [Geoscape Australia](https://geoscape.com.au/) 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](https://geoscape.com.au/data/g-naf-core/?utm_source=DISER&utm_medium=referral&utm_term=data.gov.au&utm_content=download+data&utm_campaign=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](https://geoscape.com.au/legal/data-copyright-and-disclaimer/).

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](https://data.gov.au/data/dataset/geoscape-geocoded-national-address-file-g-naf-previous-versions)

Users have the option to download datasets with feature coordinates referencing either GDA94 or GDA2020 datums.
