Remoteness Area (RA)

Within a S/T, each RA represents an aggregation of non-contiguous geographical areas which share common characteristics of remoteness. While statistical data classed to this structure may be available by S/T, characteristics of remoteness are determined in the context of Australia as a whole. Therefore, not all RAs are represented in each S/T. The categories are:

Major Cities of Australia: CDs with an average Accessibility/Remoteness Index of Australia (ARIA+) index value of 0 to 0.2
Inner Regional Australia: CDs with an average ARIA+ index value greater than 0.2 and less than or equal to 2.4
Outer Regional Australia: CDs with an average ARIA+ index value greater than 2.4 and less than or equal to 5.92
Remote Australia: CDs with an average ARIA+ index value greater than 5.92 and less than or equal to 10.53
Very Remote Australia: CDs with an average ARIA+ index value greater than 10.53
Migratory: composed of off-shore, shipping and migratory CDs (see Chapter 2).

Delimitation of Remoteness Areas

The delimitation criteria for RAs are based on the Accessibility/Remoteness Index of Australia (ARIA+) developed by the Commonwealth Department of Heath and Aged Care (DHAC) and the National Key Centre For Social Applications of GIS (GISCA). ARIA+ measures the remoteness of a point based on the physical road distance to the nearest Urban Centre in each of five size classes. For more information on how ARIA+ is defined see the Information Papers: ABS Views on Remoteness, 2001 (cat. no. 1244.0) and Information Paper: Outcomes of ABS Views on Remoteness Consultation, Australia, Jun 2001 (cat. no. 1244.0.00.001). Also refer to Census Geography Paper (cat. no. 03/01), ASGC Remoteness Classification: Purpose and Use, available from the ABS web site.

RA code

RAs are identified by unique one-digit codes within each state/territory. For unique Australia-wide identification, each RA must be used in conjunction with the S/T code.
