Australian Statistical Geography Standard

"The ASGS brings all the regions for which the ABS publishes statistics within the one framework and will be used by the ABS for the collection and dissemination of geographically classified statistics from 1 July 2011. It is the framework for understanding and interpreting the geographical context of statistics published by the ABS. The ABS also encourages the use of the ASGS by other organisations to improve the comparability and usefulness of statistics generally.
