Northern Territory: Gunlom Falls in Kakadu National Park

Gunlom Falls in Kakadu National Park is part of Waterfall Creek -- a major tributary of the South Alligator River which is the only large tropical river system to be entirely protected by a national park.

The bottom pool, with a white sandy beach, surrounded by high cliffs and palms, topped off by the 150 meter cascading waterfall was made famous by the movie Crocodile Dundee.
