The data element Address—Australian postcode, code (Postcode datafile) NNNN is not included in the listing below, as it is, strictly speaking, not a geographic indicator.

Sometimes postcodes are used in the analysis of data on a geographical basis, which involves a conversion to Statistical Local Area or Statistical Area Level 2 (Australian Bureau of Statistics geographical structures). This conversion results in some inaccuracy of information. However, in some data sets Address—Australian postcode, code (Postcode datafile) NNNN is the only geographic identifier, therefore the use of other more accurate indicators (for example, conversion from address line to Statistical Local Area or Statistical Area Level 2) is not always possible.

Some geographic indicators are:

• Australian Standard Geographical Classification (ASGC, ABS cat. no. 1216.0, effective up until 1 July 2011)
• Australian Statistical Geography Standard 2011 (ASGS, ABS cat. nos. 1270.0.55.001 to 1270.0.55.005, effective from 1 July 2011 to 11 July 2016)
• Australian Statistical Geography Standard 2016 (ASGS, ABS cat. nos. 1270.0.55.001 to 1270.0.55.005, effective from 11 July 2016)
• administrative regions
• electorates
• Accessibility/Remoteness Index of Australia (ARIA)
• Rural, Remote and Metropolitan Area Classification (RRMA)
• country.
