Look at the size of his head compared to the guide...

There are only two species of crocodile living in Australia, the Saltwater crocodile (salty) and the Freshwater crocodile (freshy). It is a fallacy that saltwater crocodiles only exist in salt water, they are known to reside in rivers, estuaries and swamps, as well as in the sea – and they can be found up to 100km inland! The main differences between the two are that the saltys are a lot bigger and bulkier and have a more rounded snout, the saltys will also quite happily kill humans to defend their territory, whilst the freshys may bite if provoked but generally will not attack humans.
Our tour around the farm was fascinating, our tour guide was incredibly knowledgeable and had an affinity with these ancient reptiles, they all have a name and a history – sometimes murderous! We learnt so much about them that we were taught not to hate or fear these creatures, but to admire and respect them.
