Im from Australia to...and its a pain... but check this out, its the official site.

Take a look at that PDF file... you will get all your questions answered
I believe one of the major reasons they ban certain fish, is because Australia had REALLY NICE tropical weather and water in certain places, where these fish could actually survive...
Especially piranhas.... there was an issue with this a few years ago. Anyway, you will realize they ban most of the aggro fish, that go on killing sprees...
Im not sure why they ban other species of arowana and stuff though...
