The G-NAF dataset is a data aggregation from multiple jurisdiction sources which depicts national and accurate information for geocoded addressing.
The use of consistent and accurate geocoded addressing supports the tourism, telecommunications, insurance banking and finance and utilities sector. Key uses include:
Better business - Many organisations rely on address databases to support efficient and effective service delivery. G-NAF assists in address verification, reduced duplication and improved service delivery. G-NAF allows organisations to develop more accurate socio-economic and demographic analysis.
Emergency response - Fast incident response depends on knowing the exact location of the emergency. For example, the ACT Emergency Services Authority uses G-NAF in its computer aided dispatch system to improve its response to 000 calls.
Personal Navigation - G-NAF is used in a growing number of websites, mobiles phones and tablets, and personal navigation products to accurately locate an address. This location intelligence provides connectivity between other services such as travel planning, imagery and features of interest information.
Fraud prevention - G-NAF has the capacity to prevent identity fraud, by allowing organisations to confirm the validity of a submitted address.

Every address within G-NAF is compared between the contributors and matched against authoritative spatial datasets to ensure that there is a legal land parcel, road or locality to verify the existence and quality of the address.
Australian State and Territory government mapping agencies and land registries (Jurisdictions), the Australian Electoral Commission (AEC), Australian Bureau of Statistics and Australia Post all contribute data to the PSMA Geocoded National Address File (G-NAF).
Assign an official address for every property in the country. Each address will include a number on a road and at least one geocode. The dataset will include the currency of the address information, as well as the relationship to any earlier addresses (e.g. following subdivision). Relationships between sub-addresses and primary addresses (e.g. in an apartment building) will also be recorded.
