I want to know where the best places are to scuba dive in Australia. 

This page offers some good insight
http://wikitravel.org/en/Scuba_diving_in_Australia

but I want something more specific, ie the exact locations.

If you can list the best dive sites, in each of the Australian states,
that will be excellent.
