Reviewer comments

The Australian Post free non-commercial use PDF does not provide any lat-long info. On the Australian Bureau of Statistics at the Postal Codes page it is stated:"Allocations have been determined using the best available information on postcode boundaries. Unfortunately, official postcode boundaries have not been updated since the early 1990s and none of the more recent interpretations have been endorsed by Australia Post."
