Alligator Rivers in the context of "Arnhem Land"

Kakadu National Park is a protected area in the Northern Territory of Australia, 171 km (106 mi) southeast of Darwin. It is a World Heritage Site. Kakadu is also gazetted as a locality, covering the same area as the national park, with 313 people recorded living there in the 2016 Australian census.

Kakadu National Park is located within the Alligator Rivers Region of the Northern Territory, covering an area of 19,804 km (7,646 sq mi), extending nearly 200 kilometres (124 mi) from north to south and over 100 kilometres (62 mi) from east to west. It is roughly the size of Wales or one-third the size of Tasmania, and is the second-largest national park in Australia, after the Munga-Thirri–Simpson Desert National Park. Most of the region is owned by the Aboriginal traditional owners, who have occupied the land for around 60,000 years and, today, manage the park jointly with Parks Australia. It is highly ecologically and biologically diverse, hosting a wide range of habitats and flora and fauna. It also includes a rich heritage of Aboriginal rock art, including highly significant sites, such as Ubirr. Kakadu is fully protected by the EPBC Act.

Ubirr, once referred to as Obiri Rock, so-named by C. P. Mountford, is a rock formation within the East Alligator region of Kakadu National Park in the Northern Territory of Australia, and is known for its rock art. It consists of a group of rock outcrops on the edge of the Nadab floodplain where there are several natural shelters that have a collection of Aboriginal rock paintings, some of which are many thousands of years old. The art depicts certain creation ancestors as well as animals from the area such as barramundi, catfish, mullet, goannas, long-necked turtles, pig-nosed turtles, rock ringtail possums, and wallabies.

From the top of Ubirr rock there is a panoramic view of the floodplains and escarpments.
