Where does the address information come from?
The address data we use comes from two main sources. These are the G-NAF address database and the Australia Post PAF (Postal Address File).
The G-NAF database is owned, created and maintained by the PSMA (an Australian Government owned company) who source their address data from ten authoritative sources including State and Territory Governments, the Australian Electoral Commission, the Australian Bureau of Statistics and other Commonwealth sources. The G-NAF database is updated quarterly.
The Australia Post PAF is owned, created and maintained by Australia Post. From the PAF we get the database of all Australian addresses to which Australia Post deliver mail. This also includes PO Box types addresses. The PAF is updated monthly.
Lastly, the Australian Bureau of Statistics also contribute data as they provide the meshblock information associated with each address.
