Special purpose codes

In the Indigenous Structure, special purpose codes are non-spatial. In all states and territories, the identifiers 94, 994 and 94 are used respectively for Indigenous Regions, Indigenous Areas and Indigenous Locations to represent No usual address. Similarly, the identifiers 97, 997 and 97 are allocated to Migratory – Offshore – Shipping. As for all other ASGS geographies, Z is used to denote Outside Australia. Special purpose codes are described in more detail in the Main Structure and Greater Capital City Statistical Areas section of this publication.
