Darwin, Northern Territory in the context of Darwin Harbour

The Northern Territory (abbreviated as NT; known formally as the Northern Territory of Australia and informally as the Territory) is an Australian internal territory in the central and central-northern regions of Australia. The Northern Territory shares its borders with Western Australia to the west (129th meridian east), South Australia to the south (26th parallel south), and Queensland to the east (138th meridian east). To the north, the Northern Territory looks out to the Timor Sea, the Arafura Sea, and the Gulf of Carpentaria, including Western New Guinea and various other islands of the Indonesian archipelago.

The NT covers 1,347,791 square kilometres (520,385 sq mi), making it the third-largest Australian federal division, and the 11th-largest country subdivision in the world. It is sparsely populated, with a population of only 260,400 as of March 2025 – fewer than half the population of Tasmania. The largest population centre is the capital city of Darwin, having about 52.6% of the Territory's population. The largest inland settlement is Alice Springs with a population of about 25,000 people.

Teleconnection in atmospheric science refers to climate anomalies being related to each other at large distances (typically thousands of kilometers). The most emblematic teleconnection is that linking sea-level pressure at Tahiti and Darwin, Australia, which defines the Southern Oscillation. Another well-known teleconnection links the sea-level pressure over Iceland with the one over the Azores, traditionally defining the North Atlantic Oscillation (NAO).

Hobart (/ˈhoʊbɑːrt/ HOH-bart) is the capital and most populous city of the island state of Tasmania, Australia. Located in Tasmania's south-east on the estuary of the River Derwent, it is the southernmost capital city in Australia. Despite containing nearly half of Tasmania's population, Hobart is the least-populated Australian state capital city, and second-smallest by population and area after Darwin if territories are taken into account. Its skyline is dominated by the 1,271-metre (4,170 ft) kunanyi / Mount Wellington, and its harbour forms the second-deepest natural port in the world, with much of the city's waterfront consisting of reclaimed land. The metropolitan area is often referred to as Greater Hobart, to differentiate it from the City of Hobart, one of the seven local government areas that cover the city. It has a mild maritime climate.

The city lies on country which was known by the local Muwinina people as Nipaluna, a name which includes surrounding features such as Kunanyi / Mount Wellington and Timtumili Minanya (River Derwent). Prior to British colonisation, the land had been occupied for possibly as long as 35,000 years by Aboriginal Tasmanians, who generally refer to themselves as Palawa or Pakana.

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.

Arnhem Land is a historical region of the Northern Territory of Australia. It is located in the north-eastern corner of the territory and is around 500 km (310 mi) from the territorial capital, Darwin. In 1623, Dutch East India Company captain Willem Joosten van Colster (or Coolsteerdt) sailed into the Gulf of Carpentaria and Cape Arnhem is named after his ship, the Arnhem, which itself was named after the city of Arnhem in the Netherlands.

The area covers about 97,000 km (37,000 sq mi) and has an estimated population of 16,000, of whom 12,000 are Aboriginal and Torres Strait Islander people. Two regions are often distinguished as East Arnhem (Land) and West Arnhem (Land). The region's service hub is Nhulunbuy, 600 km (370 mi) east of Darwin, set up in the early 1970s as a mining town for bauxite. Other major population centres are Yirrkala (just outside Nhulunbuy), Gunbalanya (formerly Oenpelli), Ramingining, and Maningrida.

The Australian monsoon (AUM), also known as the Australian summer monsoon (ASM), and the Australian-Indonesian monsoon (AIM), is a monsoon system that increases thunderstorms and rainfall over many areas of Indonesia and northern Australia, from the far northern tropics of the region to the semi-arid zone of Australia, typically between November and mid-March, which is the wet season of many parts of northern Australia and Indonesia.

The origin of the Australian monsoon (AUM) is comparable the North African monsoon, since both develop from the seasonal motion of the Intertropical Convergence Zone (ITCZ) and the connected meridional shift in the overturning Hadley circulation, which lead to a pronounced rainfall seasonality. From the end of the 19th century, the force of the Australian monsoon has been measured by the summer precipitation at Darwin.

The Warrego Highway is located in southern Queensland, Australia. It connects coastal centres to the south western areas of the state, and is approximately 715 km in length. It takes its name from the Warrego River, which is the endpoint of the highway. The entire highway is part of the National Highway system linking Darwin and Brisbane: formerly National Highway 54, Queensland began to convert to the alphanumeric system much of Australia had adopted in the early-2000s and this road is now designated as National Highway A2.

A submarine communications cable is a cable laid on the seabed between land-based stations to carry telecommunication signals across stretches of ocean and sea. The first submarine communications cables were laid beginning in the 1850s and carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858.

Submarine cables first connected all the world's continents (except Antarctica) when Java was connected to Darwin, Northern Territory, Australia, in 1871 in anticipation of the completion of the Australian Overland Telegraph Line in 1872 connecting to Adelaide, South Australia and thence to the rest of Australia.

Alice Springs (Eastern Arrernte: Mparntwe, [ᵐbaⁿɖʷə]) is a town in the Northern Territory, Australia; it is the third-largest settlement after Darwin and Palmerston. The name Alice Springs was given by surveyor William Whitfield Mills after Alice, Lady Todd (née Alice Gillam Bell), wife of the telegraph pioneer Sir Charles Todd. Known colloquially as The Alice or simply Alice, the town is situated roughly in Australia's geographic centre. It is nearly equidistant from Adelaide and Darwin.

The area is also known locally as Mparntwe to its original inhabitants, the Arrernte, who have lived in the Central Australian desert in and around what is now Alice Springs for tens of thousands of years.

Victoria River Downs Station, also known as Victoria Downs and in the past sometimes referred to as The Big Run, is a pastoral lease that operates as a cattle station in the Northern Territory of Australia, established in 1883.

It is 686 kilometres (426 mi) south of Darwin by road.

The Battle of Timor occurred in Portuguese Timor and Dutch Timor during the Second World War. Japanese forces invaded the island on 19 February 1942 and were resisted by a small, under-equipped force of Allied military personnel—known as Sparrow Force—predominantly from Australia, the United Kingdom, and the Dutch East Indies. Following a brief but stout resistance, the Japanese succeeded in forcing the surrender of the bulk of the Allied force after three days of fighting, although several hundred Australian commandos continued to wage an unconventional raiding campaign. They were resupplied by aircraft and vessels, based mostly in Darwin, Australia, about 650 km (400 mi) to the southeast, across the Timor Sea. During the subsequent fighting, the Japanese suffered heavy casualties, but they were eventually able to contain the Australians.

The campaign lasted until 10 February 1943, when the final remaining Australians were evacuated, making them the last Allied land forces to leave Southeast Asia following the Japanese offensives of 1941–1942. As a result, an entire Japanese division was tied up on Timor for more than six months, preventing its deployment elsewhere. Although Portugal was not a combatant, many Timorese and European Portuguese civilians fought with the Allies or provided them with food, shelter and other assistance. Some Timorese continued a resistance campaign following the Australian withdrawal. For this, they paid a heavy price and tens of thousands of Timorese civilians died as a result of the Japanese occupation, which lasted until the end of the war in 1945.

Gunbalanya (also spelt Kunbarlanja, and historically referred to as Oenpelli) is a town in west Arnhem Land in the Northern Territory of Australia, about 300 kilometres (190 mi) east of Darwin. The main language spoken in the community is Kunwinjku (a dialect of Bininj Kunwok). At the 2021 Australian census, Gunbalanya had a population of 1,177, of largely Aboriginal Australian identity.

Only accessible by air during the wet season, Gunbalanya is known for its Aboriginal art, in particular rock art and bark painting. It has a range of services, including a police station, school and community arts centre, Injalak Arts.

Ramingining is an Aboriginal Australian community of mainly Yolngu people in the Northern Territory, Australia, 560 kilometres (350 mi) east of Darwin. It is on the edge of the Arafura Swamp in Arnhem Land. Wulkabimirri is a tiny outstation (homeland) nearby, and Murwangi, further south, is part of the Ramingining Homelands. Marwuyu Gulparil, also known as Gulparil Marwuyu or just Marwuyu, is another remote community to the south of Ramingining.

Maningrida (Ndjébanna: Manayingkarírra, Kuninjku: Manawukan) is an Aboriginal community in the heart of the Arnhem Land region of Australia's Northern Territory. Maningrida is 500 km (311 mi) east of Darwin, and 300 km (186 mi) north east of Jabiru. It is on the North Central Arnhem Land coast of the Arafura Sea, on the estuary of the Liverpool River.

The Kunibídji (Ndjebbana) people are the traditional owners of this country. Major players in the town's economic and political life include the West Arnhem Regional Council, the Bawinanga Homelands Aboriginal Corporation, the Maningrida Progress Association, and Mala'la Health Service Aboriginal Corporation. Maningrida Arts & Culture, with its Djómi Museum, managed by the Bawinanga Homelands Aboriginal Corporation, is a major art centre, known both nationally and internationally.

The Tiwi people (or Tunuvivi) are one of the many Aboriginal groups of Australia. Nearly 2,000 Tiwi people live on the Tiwi Islands. The landmass of the Tiwi Islands is made up mainly of Bathurst and Melville Islands, both located about 48 kilometres (30 miles) from Darwin. The Tiwi language is a language isolate, with no apparent link to the languages of Arnhem Land or of other Aboriginal Australians beyond recent linguistic interaction as a result of the federal government's Stolen Generations relocation policies. Tiwi society is based on matrilineal descent, and marriage plays a very important part in many aspects of their lives. Art and music form an intrinsic part of their societal and spiritual rituals as the Tiwi people tend to follow a certain form of indigenous Dreamtime belief system alongside Roman Catholicism.

The Tiwi Islands (Tiwi: Ratuati Irara meaning "two islands") are part of the Northern Territory, Australia, 80 km (50 mi) to the north of Darwin adjoining the Timor Sea. They comprise Melville Island, Bathurst Island, and nine smaller uninhabited islands, with a combined area of 8,320 square kilometres (3,212 sq mi).

Inhabited before European settlement by the Tiwi (Tiwi: Tunuvivi), an Aboriginal Australian people, the islands' population was 2,348 at the 2021 census. National Geographic has characterised contemporary Tiwi Islands society as reflecting an enduring fusion between the indigenous Tiwi people's traditional beliefs and these later European settlers' Catholicism.
