ARIA Lookup Tool
The Accessibility/Remoteness Index of Australia (ARIA) categorises areas according to their distance from “service centres”.
ARIA defines five categories of remoteness and is available for a variety of geographical units including localities, Census Collection Districts (CCDs), Statistical Local Areas (SLAs) and postcodes.
PoCoG currently uses the 2011 remoteness data, which is freely available from the Australian Bureau of Statistics, to match your postcode or suburb data to the remoteness area. While the postcode data is the minimum requirement, suburb-state data returns more accurate results.
The ARIA lookup tool provides an easy means of working out the ARIA classification for either of these types of data because it enables you to batch process all of your records at once rather than one by one.
