This dataset is the Australian Drainage Divisions (ADD) boundaries as defined by the Australian Statistical Geography Standard (ASGS): Volume 3 - Non ABS Structures, July 2016. For the original data and more information, refer to the Australian Bureau of Statistics' Issue. The ABS encourages the use of the ASGS by other organisations to improve the comparability and usefulness of statistics generally, and in analysis and visualisation of statistical and other data. The Australian Statistical Geography Standard (ASGS) brings together in one framework all of the regions which the ABS and many others organisations use to collect, release and analyse geographically classified statistics. The ASGS ensures that these statistics are comparable and geospatially integrated and provides users with an coherent set of standard regions so that they can access, visualise, analyse and understand statistics.

Access API Export Data Destination Zones are co-designed with state and territory transport authorities. DZNs are designed from either whole or aggregations of Mesh Blocks (MB) and they align to Statistical Area Level 2 boundaries. They have no relationship to Statistical Area Level 1 boundaries. Destination Zones were incorporated as part of the ASGS for the first time in 2021. Further information about these regions can be found in the following publication: Australian Statistical Geography Standard (ASGS) Edition 3 https://www.abs.gov.au/statistics/standards/australian-statistical-geography-standard-asgs-edition-3/jul2021-jun2026
