There are two species. The Estuarine, or Saltwater Crocodile which is the worlds largest living species, and the Johnstons Freshwater Crocodile.
There is also the Pygmy Freshwater Crocodile found usually in the escarpment areas of Arnhem Land, but tests indicate that it is the same species as the Freshwater Crocodile. It is believed it has much less food availability and is the reason it remains smaller.
