- Mesh Block (MB)
- Statistical Area Level 1 (SA1)
- Statistical Area Level 2 (SA2)
- Statistical Area Level 3 (SA3)
- Statistical Area Level 4 (SA4)
- Greater Capital City Statistical Areas (GCCSA)
- State and Territory (S/T)

Nomenclature
File names have the format <file type>_<2021>_<AUST>_<GDA> where:
- <file type> represents the type of boundaries in each file
- MB = Mesh Block
- SA1 = Statistical Area Level 1
- SA2 = Statistical Area Level 2
- SA3 = Statistical Area Level 3
- SA4 = Statistical Area Level 4
- GCCSA = Greater Capital City Statistical Area
- STE = State and Territory
- AUS = Australia
- <2021> represents 2021 the year of the Australian Statistical Geography Standard (ASGS) Edition 3
- <AUST> indicates the data covers all of Australia
- <GDA> indicates the Geocentric Datum of Australia used, and may equal GDA94 or GDA2020
Within the files, the States and Territories are identified by unique one-digit codes.

Data quality
Lineage: Mesh Block boundaries were created using various sources including the Geoscape digital datasets and ABS boundaries, zoning information from state planning agencies, and imagery. State borders are aligned to Australia’s Land Borders dataset produced by Geoscience Australia.
Positional accuracy: Positional accuracy is an assessment of the closeness of the location of spatial objects in relation to their true positions on the earth's surface.
The positional accuracy includes:
- a horizontal accuracy assessment
- a vertical accuracy assessment
Positional accuracy for ABS boundaries is dependent on the accuracy of the features they have been aligned to.
ABS boundaries are aligned to layers supplied by Geoscape with an accuracy of +/-50 mm. Geoscape layers and their positional accuracy are as follows:
- Transport and Topography: +/- 2 metres in urban areas and +/- 10 metres in rural and remote areas.
- CadLite: +/- 2 metres in urban areas and +/- 10 metres in rural and remote areas.
- Administrative Boundaries: Derived from the cadastre data from each Australian state and territory jurisdiction.
- Greenspace and Hydrology: 90% of well-defined features are within 1mm (at plot scale) of their true position, for example 1:500 equates to +/- 0.5 metre and 1:25,000 equates to +/- 25 metres. Relative spatial accuracy of these themes reflects that of the jurisdictional source data. The accuracy is +/- 2 metres in urban areas and +/- 10 metres in rural and remote areas. No "shift" of data as a means of "cartographic enhancement" to facilitate presentation has been employed for any real world feature.
- Precision: Boundary coordinates have been rounded to 8 decimal places, equivalent to 1.1132 mm at the equator. All ABS boundaries have been generalised to 5 cm with a 7.5 cm shared boundary tolerance.
- Attribute accuracy: All codes and labels for all levels within the ASGS Edition 3 Main Structure and GCCSAs are fully validated.
- Logical consistency: Regions are closed polygons. Attribute records without spatial objects have been included in the data for administrative purposes.
- Completeness: All levels of the Main Structure and GCCSAs within ASGS Edition 3 are represented.
XML metadata files
The compressed download files include geospatial metadata data for each region type in Extensible Markup Language (XML) format. The geospatial metadata conforms to International Organisation for Standardization (ISO) geospatial metadata standard, ISO 19115:2003, and the associated XML implementation schema specified by ISO 19139:2012.
