More information about G-NAF is available on the PSMA web site.

Suburb Name:Geographical names (DEHAA) allocate the suburb name.  This is done in consultation with Aust Post, Police, LG etc conforming to existing guidelines.  This is generally the formalisation of an existing name or has local significance to the area to be named.

Maintenance and Location:At this stage no one assumes custodial responsibility for population and maintenance of the address database.  It is done on client demand by linking the valuation property address file with the DCDB.
The match rate varies from > 95% in built up areas to <10% in rural areas.
