Mesh Blocks (MBs) are the smallest geographical area defined by the ABS. They are designed as geographic building blocks rather than as areas for the release of statistics themselves. All statistical areas in the Australian Statistical Geography Standard (ASGS), both ABS and Non ABS Structures, are built up from one or more MBs.
The National groundwater dataset is derived from multiple inputs aggregated together to provide a national coverage for all of Australia.
The dataset provides a nationally consistent set of groundwater boundaries and properties including aquifer boundaries, geometry, salinity, yield and hydraulic conductivity.
The national groundwater dependent ecosystems is a dataset aggregated from different sources to produce a national coverage over all of Australia.
Groundwater Dependent Ecosystems (GDE) is ecological and hydrogeological information on known groundwater dependent ecosystems and ecosystems that potentially use groundwater.
The Administrative Boundaries datasets are Australia’s most comprehensive national collection of boundaries including government, statistical and electoral boundaries.
Administrative Boundaries is produced by PSMA Australia Limited (PSMA), an unlisted public company formed by the nine governments of Australia to collate and standardise, format and aggregate location data from each of the jurisdictions into authoritative location based national datasets.
