Answers:    There is an excellent Australian aquarist website called 'Aquarium Life' (at http://www.aquariumlife.com.au) that have a forum with devoted and enthusiastic members who would be able to give a hand you.

Registration is free, however there are some more special memberships that can cost around $AU25...

Anyway, I had a look and all I could see from my brief rummage through was that this guy in the eastern suburbs of Melbourne is selling his tank which includes some rocks... probably you could contact him about just purchasing the rocks? Here is the URL:

Alas, this may not be quite what you're after, but whether you signed up and posted this same question, I bet you'd get excellent and informative answers.

Good luck and I hope 'Aquarium Life' helps!!
