This vast wilderness, occupying some 13,000 square kilometres, is, like Arnhem Land, owned by the Aboriginal people of the Alligator River region. The park is jointly managed by the Australian National Parks and Wildlife Service and the tribal elders of the area. The park gained worldwide notice when it was placed on the World Heritage List in 1981. The only thing wrong is the name. There isn't an alligator in all Australia.
Alligators are broad-snouted and are found only in the southern United States and eastern China.
Crocodiles, on the other hand, have pointed snouts and dwell in tropical waters. Australia has no alligators, only crocodiles. An American sea captain named the rivers when he discovered the three watercourses, calling them the West, South and East Alligator Rivers. The last 36 kilometres of the Arnhem Highway leads to Park Headquarters, and here you can get your orientation to Kakadu. In deciding where to go, a place not to be missed is Obiri Rock.
