Australian Institute of Health and WelfareComments:
The data element 'Person (address)—Australian postcode (Postcode datafile), code [NNNN]' is not included in the above listing, 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 'Person (address)—Australian postcode (Postcode datafile), code [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.
