Gregory's Server@Dangerous_beans @xssfox Locality is a formally defined construct that represents a geographically bounded area. Localities are maintained by the varies State lands Authorities and they define the address of all land parcels contained within. Australia Post define geographic postcodes in terms of the Localities they serve, and they adopt the boundaries precisely.

 @Dangerous_beans @xssfox It’s possible. Localities come from a lands management and surveying background, not from a stats background. Geoscience Australia do act as a national umbrella group for all the State lands data, and the States do coordinate and standardise pretty well with each other on this. This might be useful https://www.ga.gov.au/scientific-topics/national-location-information/nationalmap  |
@railmaps @xssfox ah, it's state level. i can't find a list to check, the free publication on auspost isn't much use here
It appears that localities only roughly match ABS categories, so it could be that localities aggregate to postcodes but the two can't be linked to other systems
