Daavid,
The Great dividing Range to the North of Melbourne and the lack of flowing waterways to the East (between Moe and Warrigul) are what has stopped C. longicollis from entering Melbourne naturally. These are geological barriers as opposed to climatic ones, so now that they are here they are breeding successfully and have effectively turn feral.
Chelodina longicollis is not the only native species to be living in Melbourne outside of its natural range.....Physignathus lesueurii, Christinus marmoratus, Emydura macquarii and Litoria fallax are all breeding and surviving around Melbourne. Whether they should be allowed to continue too is another can of worms completely though
Cheers,
Scott
