======== Overview ======== Data product specification title -------------------------------- G-NAF Product Description Reference date -------------- May 2021 Informal description of the data product ---------------------------------------- G-NAF (Geocoded National Address File) is a trusted index of Australian address information. It contains the state, suburb, street, number and coordinate reference (or “geocode”) for street addresses in Australia. G-NAF uses existing and recognised address sources (referred to as contributors) from the state and territory government land records and Commonwealth government agencies. The Mesh Block data is sourced from the Australian Bureau of Statistics (ABS) and is part of their Australian Statistical Geography Standard (ASGS). A rigorous process is used that involves textual address comparison, matching and geospatial validation to provide both national consistency and national coverage.

About AS/NZ 4819:2011 --------------------- The standard AS/NZ 4819:2011 is intended for use by agencies that are responsible for addressing. The goal of AS/NZ 4819:2011 is to specify requirements for assigning addresses that can be readily and unambiguously identified and located. To achieve this goal, the objectives of the standard are: * Localities are to enable addresses to be uniquely and clearly identified * Assigned names for roads or other primary means of access enable addresses to be readily and uniquely identified * Assigned address numbering enables address sites to be readily located * Signage enables assigned addresses to be readily identified and located * Address information enables sites to be readily located. About AS4590:2006 ----------------- The standard AS4590:2006 sets out requirements of data elements for the interchange of client information. There are several elements specific to addressing. As G-NAF contains both old and new addresses, it is more closely related to the structure in AS4590:2006. About the National Address Management Framework ----------------------------------------------- The National Address Management Framework (NAMF) has been developed as a national, coordinated approach to address management. It is a consistent, standards-based framework which will guide the process for verifying addresses and provide a standard for exchange of address data. Appendix A sets out the relationship between G-NAF, AS450:2006 and NAMF fields.
