ASGS (2011 Edition) - Indigenous Structure - Indigenous Region (IREG) Boundaries

Indigenous Regions are large geographical units loosely based on the former Aboriginal and Torres Strait Islander Commission boundaries. They are created by combining together one or more Indigenous Areas. The greater population of Indigenous Regions enables the highest level of analysis of attribute data through greater cross classification of variables compared with Indigenous Areas and Indigenous Locations. For the 2016 Australian Statistical Geography Standard (ASGS) 58 Indigenous Regions are defined to cover the whole of geographic Australia. Indigenous Regions do not cross State and Territory borders.

There are non-spatial Indigenous Regions for Migratory - Offshore - Shipping and No Usual Address in each State and Territory.

Indigenous Region Names

Indigenous Region Names are allocated by ABS and are generally based upon a commonly identified name or combination of names for the area/community which the boundary encompasses.

Indigenous Region Coding Structure

Indigenous Regions are allocated a two digit code. This is prefixed by a single digit State and Territory code to complete the Indigenous Region code.

Special purpose codes are included as balancing items. Statistical Area Level 1 (SA1) allocated to these codes are not part of a distinct Indigenous Region.

  • Codes ending in 94 are reserved for cases where people are coded to No Usual Address SA1s.
  • Codes ending in 97 are reserved for cases where people are coded to Migratory, Offshore and Shipping SA1s.


| STE Name | STE Code | IREG Code |              IREG Name                 |
| Victoria |        2 |       201 | Melbourne                              |
| Victoria |        2 |       202 | Victoria exc. Melbourne                |
| Victoria |        2 |       294 | No usual address (Vic.)                |
| Victoria |        2 |       297 | Migratory - Offshore - Shipping (Vic.) |

The codes used for the 2016 Indigenous Regions may not match those used in 2011 in some instances. In future ASGS editions, it may also be necessary to allocate new codes . Changes to codes occur where an Indigenous Region is abolished or changes significantly for new editions of the ASGS, the Indigenous Region identifier will be retired and the replacement Indigenous Region(s) given a new code. Correspondences enabling translation of data from 2011 to 2016 and how these changes have been applied will be released with this volume.
