We take the guesswork out of location.
Geoscape is the digital Australia – a comprehensive representation of our built environment. It describes the addresses, land, buildings and transport networks across Australia’s 7.6 million km2. We continuously source, process and deliver data to various endpoints, including APIs and a self-service portal.

In most cases, there is no one primary custodian of addressing in Australia. The validation and authorisation of an address generally rests with local governments or other government departments that manage land, with general input from property developers. The state and territory land agencies have a responsibility to collate and keep a concise record of all addresses, but only for their jurisdictions. There is no federal legislation to form a consistent specification of addressing nationally.
G-NAF (Geocoded National Address File) is recognised as the most requested high-value dataset. It contains address data including the state, suburb, street, number and coordinate reference (or “geocode”) for street addresses in Australia. What makes G-NAF unique is the rich data associated with each address including the linking of official addresses with in-use addresses, linkages to other datasets including ABS data and rankings based on input from multiple contributors.
G-NAF does not contain any personal information or details relating to an individual or business.
G-NAF contains addresses for physical locations. For an address to be included in G-NAF, it must meet pre-defined criteria for what constitutes a valid address. For example, addresses with no street numbers are not usually included in G-NAF.
There are over 14 million addresses in G-NAF with more than 50,000 addresses added each release.
Geoscape receives over 30 million addresses each quarter from 10 contributors, including state and territory government land agencies and Commonwealth sources.
G-NAF contains addresses for all states and territories of Australia including external localities such as Christmas Island, Cocos (Keeling) Islands and Norfolk Island.
An address not appearing in G-NAF may be the result of any of the processes at either the contributor or Geoscape end of production. If you would like to check the inclusion or exclusion of an address, please contact your local government or state land agency.
G-NAF is produced from data provided to Geoscape by contributor organisations. If you would like to add or change an address, you will need to contact your local government or state land agency. In some cases we may be able to provide some assistance. Use the Contact Us form to make an enquiry.
Addresses are created or changed by various authorities. These addresses need to make their way through the relevant processes, including various levels of government, before they reach Geoscape as a contribution to G-NAF. Geoscape receives addresses from contributors on an ongoing basis and feeds them through a 13 week production process. The cyclical production process means the currency of an address can vary between 2 months to 6 months upon the release of G-NAF.
G-NAF has a quarterly update release cycle occurring in February, May, August and November each year.
No. An address does not necessarily mean there will be a building there. Addresses are used to not only label land parcels, properties and buildings, they’re also used for locating a variety of assets such as ATMs, tree plantations, reserves, parks and utility substations.
