The Geocoded National Address File (referred to as G-NAF) is Australia’s authoritative, geocoded address file.

G-NAF is one of the most ubiquitous and powerful spatial datasets. It contains more than 13 million Australian physical address records. The records include geocodes. These are latitude and longitude map coordinates. G-NAF does not contain any names or personal information.

G-NAF is produced by PSMA Australia Limited (PSMA), an unlisted public company formed by the nine governments of Australia to collate and standardise, format and aggregate location data from each of the jurisdictions into authoritative location based national datasets.

This initiative to make the G-NAF openly available has been achieved through collaboration between PSMA and the Commonwealth and State and Territory Governments.

Updated versions of the G-NAF will be published on a quarterly basis from February 2016.

As at November 2019, users have the option to download datasets with feature coordinates referencing the new Geocentric Datum of Australia 2020 (GDA2020) in addition to datasets on the GDA94 datum.

For GDA2020 datasets, the name of the zip folder and the root folder (once extracted) include a reference to GDA2020. For GDA94 datasets, the zip and root folder names do not contain the datum name (i.e. they remain the same as previous releases).

For example, the zip and root folder for G-NAF downloaded in GDA2020 for November 2019 looks like this:

   •    NOV19_GNAF_PipeSeperatedValue_GDA2020

The zip and root folder for GNAF in GDA94 for November 2019 looks like this:

   •    NOV19_GNAF_PipeSeperatedValue

Irrespective of the datum chosen, files within the respective folder use exactly the same naming structures.

What to Expect When You Download G-NAF

G-NAF is a complex and large dataset (approximately 5GB unpacked), consisting of multiple tables that will need to be re-joined prior to use, as the dataset is primarily designed for application developers and large-scale spatial integration.
