The Adelaide River is a river in the Northern Territory of Australia.
The river rises in the Litchfield National Park and flows generally northwards to Clarence Strait, joined by eight tributaries including the west branch of the Adelaide River, Coomalie Creek, Margaret River and Marrakai Creek, before discharging into its mouth in Adam Bay in the Clarence Strait. The river descends 151 metres (495 ft) over its 238-kilometre (148 mi) course. [1] The catchment area of the river is 7,640 square kilometres (2,950 sq mi). [2]
The Adelaide River is crossed by both the Stuart Highway, adjacent to the township of Adelaide River, and the Arnhem Highway near Humpty Doo.
The Adelaide River is well known for its high concentration of saltwater crocodiles, along with other wildlife including white-bellied sea eagles, whistling kites, freshwater crocodiles, bull sharks and black flying-fox. Its lower reaches form part of the Adelaide and Mary River Floodplains Important Bird Area. Waters of this river are also home to endangered speartooth shark and critically endangered largetooth sawfish. The river also contains a notable introduced population of Siamese fighting fish. [3]
Indigenous Australians including the Warray and Kungarakan owned the lands among the river for millennia.
Lieutenant Fitzmaurice, under the command of John Lort Stokes, sighted the river on a boating expedition. The expedition was part of the Admiralty surveying ship HMS Beagle's voyage in 1839, and the river was named in honour of Queen Adelaide. [4]

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.

The Black Jungle Conservation Reserve is a protected area in the Northern Territory of Australia near the territorial capital of Darwin. The rural area of Darwin and its development has a contrasting history to the more southern regions and their rural zones. The development of the rural area around Darwin occurred after 1950 as agricultural ventures were trialed. Prior to this the area was tropical savanna with pockets of monsoon rainforest and melaleuca swamps, unchanged for thousands of years, except by the traditional Aboriginal owners of the land who hunted and gathered and managed the landscape with fire. Black Jungle Conservation Reserve is a part of the Adelaide River Coastal Floodplain system which encompasses Black Jungle and Lambells Lagoon Conservation Reserves, Fogg Dam, Leaning Tree Lagoon Nature Park, Melacca Swamp and Djukbinj National Park. These Reserves encompass a range of wetland types and form part of the internationally significant Adelaide River floodplain.
