Trouble with cats is they often destroy bird populations as well, not sure how much of a problem this is in Australia, but in New Zealand feral cats are up there with pests that need to wiped off any island that is to be rehabilitated.

The Stephens Island Wren is an excellent example of this http://en.wikipedia.org/wiki/Stephens_Island_Wren

Feral cats are a massive problem in rural Australia. They decimate small native mammals. The idea of introducing them to control rats and save native animals is insane - the cats would wipe out everything smaller than them.

Introducing a foreign species into an ecosystem has failed spectacularly so many times I cannot believe people still propose it.
