Geoscape G-NAF: Australia's Authoritative Geocoded Address File

Geoscape G-NAF is Australia's authoritative geocoded address file, containing over 15 million physical address records. It is built and maintained by Geoscape Australia using authoritative government data and is updated quarterly. The dataset includes latitude and longitude coordinates but does not contain personal information.

Use Cases

• Geocoding addresses for mapping applications based on latitude and longitude coordinates.
• Analyzing national address distribution patterns based on over 15 million records.
• Integrating authoritative address data into business systems based on quarterly updates.
• Validating address data for mail delivery based on the dataset's use restriction clause.

Strengths

• Contains over 15 million Australian physical address records.
• Includes geocodes (latitude and longitude coordinates).
• Updated quarterly, with a February 2026 release showing an increase of 32,711 addresses.
• Provides coordinates referencing both GDA94 and GDA2020 datums.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to government source data.
