The Kakadu's National Park, which is renowned for the richness of its Aboriginal cultural sites, has been occupied by the tribal group for over 40,000 years. Thus, unsurprisingly, there are nearly 5,000 recorded locations within the confines of this UNESCO World Heritage site. There are paintings upto 20,000 years old providing an eye-catching recount of the life of the Aboriginals - an account of the animals the tribal hunt and the objects they use. Rock galleries at Ubirr and Burrungkuy are home to naturalistic paintings of animals, traditional x-ray art, and narration of Aboriginal contact with the early European explorers.
