"The freshwater crocodile (Crocodylus johnstoni), also known as the Australian freshwater crocodile, Johnston's crocodile or colloquially as freshie, is a species of reptile endemic to Australia. Found in the northern regions of Australia, it is much smaller than the other Australian species, the saltwater crocodile, which is responsible for attacks on people. Although they will bite if disturbed or feel threatened, freshwater crocodiles are not known as man-eaters and their prey is generally of a much smaller size. However as prey for larger adults can include wallabies, small children should not be left unattended in their presence, although no such attacks have been reported. They will usually ignore people when sunning themselves beside a swimming hole, provided they have a relatively peaceful spot."
"They are found in the states of Western Australia, Queensland, and the Northern Territory. Main habitats include freshwater wetlands, billabongs, rivers, and creeks. It competes poorly with Saltwater crocodiles but is saltwater tolerant. As an adult, its diet consists of birds, bats, reptiles, amphibians and fish, although larger individuals may take prey as large as a wallaby. This species can live in areas where Saltwater Crocodiles cannot, and are known to inhabit areas above the escarpment in Kakadu National Park and in very arid and rocky conditions (such as Katherine Gorge, where they are very common and relatively safe from saltwater crocodiles during the dry season.) However, they are still consistently found in low-level billabongs, living alongside their larger evolutionary cousins within the tidal reaches of rivers...as well as far inland."

There have been a (very limited) number of incidents where people have been bitten whilst swimming with freshwater crocodiles, and others incurred during scientific study. An example of a recorded attack by a freshwater crocodile on a human took place at Barramundi Gorge (also known as Maguk) in Kakadu National Park and resulted in very minor injuries to the victim, who managed to swim and walk away from the attack. It is believed the victim swam directly over the small crocodile. However in general it is still considered safe to swim with this species, so long as they are not aggravated." --> OMG, I swam at Barramundi Gorge too...
