“The Soil and Landscape Grid of Australia map products can be viewed in Google Earth by downloading this KML file 0.5Mb. “
Pretty damn impressive amound of soil data from the CSIRO using Google Earth as the presentation media.

Just download the klm file and hit run when asked what to do.
It will fire up Google Earth (if you have it on your computer) and populate the menu with a heap of selectables.
Enjoy.
