G-NAF Core makes accessing geocoded addresses easier.
It provides the core richness and power of G-NAF in a comprehensive, but easy-to-use format.
We build G-NAF Core using G-NAF, our geocoded national address file, which distils over 50 million contributed addresses into more than 15.2 million G-NAF addresses.
G-NAF Core reduces the complexity of G-NAF by delivering the data in a simplified single-table model. Approximately 50 tables in G-NAF are reduced to two: one for current addresses and one for retired addresses. This cuts down the need to select fields and build data relationships to access G-NAF’s essential address data, making it easier to use with less technical effort.
G-NAF Core is for all.
G-NAF Core is available, fee-free, from Geoscape Australia for use in accordance with this End User License Agreement (EULA).
The EULA terms are based on the Creative Commons Attribution 4.0 International license (CC BY 4.0). However, an important restriction has been added relating to the use of G-NAF Core for the sending of mail.
G-NAF Core must not be used for the generation of an address or a compilation of addresses for the sending of mail unless the user has verified that each address to be used for the sending of mail can receive mail by reference to a secondary source of information.
For guidance on complying with the EULA’s attribution requirements, please see the FAQ “How should I attribute G-NAF Core?” below.

How is G-NAF Core different from G-NAF?
G-NAF Core combines the essential G-NAF address fields into a simple, single-table data list of addresses. G-NAF Core is not a replacement for G-NAF. It doesn’t replicate the full functionality of G-NAF for detailed address data analysis, instead, it is designed to simplify and streamline the process of utilising address data for investigation or use in applications.
G-NAF Core includes a single geo-coordinate (latitude/longitude) for each address. It also features a readable ‘address label’ field which combines address attributes into a single, descriptive string. A file of retired addresses is included in G-NAF Core for reference. This file is a list of historical addresses previously contributed to G-NAF but is no longer recognised or supported in the current list.
Since G-NAF Core is not a replacement for G-NAF, if you are after advanced use and insights from addressing information, the full G-NAF dataset is your best bet. Access G-NAF at data.gov.au

G-NAF Core FAQs
G-NAF Core is a simplified version of the G-NAF dataset. It has been designed to provide a more consumable list of Australian address data. It minimises the requirement to select fields and build data relationships to access the essential address data contained in G-NAF.
G-NAF Core must not be used for the generation of an address or a compilation or address for the sending of mail unless the user has verified that each address to be used for the sending of mail can receive mail by reference to a secondary source of information.

G-NAF is produced from data provided to Geoscape Australia by contributor organisations, including land agencies in each state and territory agency. If you would like to report an address issue, we recommend contacting your local government or state land agency in the first instance. In some cases, we may be able to provide some assistance. You can contact us using the contact us form here.
The G-NAF Core files are very large and contain millions of lines of information. Make sure you are using an appropriate application to open the file.
The ‘retired’ file is a historical list of addresses that have been contributed to G-NAF in the past but are no longer recognised or supported. In some cases, the addresses have been replaced with an updated address with a new locality or street name.
The first release of G-NAF Core is in August 2022. As future releases are added we will continue to make the previous versions available.
