Australian Aboriginal art in the context of "Aboriginal Australian culture"

Alligator Rivers is the name of an area in an Arnhem Land region of the Northern Territory of Australia, containing three rivers, the East, West, and South Alligator Rivers. It is regarded as one of the richest biological regions in Australia, with part of the region in the Kakadu National Park. It is an Important Bird Area (IBA), lying to the east of the Adelaide and Mary River Floodplains IBA. It also contains mineral deposits, especially uranium, and the Ranger Uranium Mine is located there. The area is also rich in Australian Aboriginal art, with 1500 sites. The Kakadu National Park is one of the few World Heritage sites on the list because of both its natural and human heritage values. They were explored by Lieutenant Phillip Parker King in 1820, who named them in the mistaken belief that the crocodiles in the estuaries were alligators.

Bark painting is an Australian Aboriginal art form, involving painting on the interior of a strip of tree bark. While examples of painted bark shelters were found in the south-eastern states (then colonies) of Tasmania, Victoria, and New South Wales in the 19th century, as well as later on bark shelters in northern Australia, it is now typically only found as a continuing form of artistic expression in Arnhem Land and other regions in the Top End of Australia, including parts of the Kimberley region of Western Australia.

Bark paintings were traditionally produced (especially among the Yolngu peoples) for instructional and ceremonial purposes and were transient objects. Today, they are keenly sought after by collectors and public arts institutions.
