Australian Postcode Boundaries for Google Earth (KMZ)
I searched for ages, and couldn't find where to get a KMZ / KML file for Google Earth that had all the Australian Postcode Boundaries in it... So I made one based on the 1270.0.55.003 - Australian Statistical Geography Standard (ASGS): Volume 3 - Non ABS Structures, July 2011 . I claim no additional copyright on this, but please ensure you are able to use the data according to the ABS Copyright rules Here is the download link
