There is a great book on all Hawaiian inverts by a guy named John Hoover, or maybe Hooker. Buy that, great reference material with all the mantis shrimp you can find in Hawaiin waters. Where in Australia do you live? I went to Townsville in 1999, loved it and want to go back to Australia for vacation again as soon as possible. I should have my PADI certification soon and think it would really be cool to dive around the great barrier reef. Anyways...hope the book helps.
ive asked roy caldwell already and he has sent me some awesome pics but i want to create a kind of mantis library so you can log on and try and find the species of mantis you own and maybe some info about that species etc. all credit will be given to the owner. if anyone has some pics please email them to me at firstname.lastname@example.org and maybe a bit of info about how you have kept them etc.
