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 nocopyright on this, but please ensure you are able to use the data according to the ABS Copyright rules
