awesome pics, i live in aus too. even though you are allowed to collect some stuff from the wild i personally wouldnt take anything from that reef. every thing there is part of an eco system and all fits into a hierarchy where everything depends on each other for the ecosystem to survive. taking out things is just going to damage the ecosystem, and we underestimate our impact on reefs so much its not funny. better to buy things at a shop, its not going back if it lands in a shop, whether tank bred or not.
