Travel Wild explores Australia's top end the Northern Territory. Host Lin Sutherland helicopters through some of the countries most stunning canyons and explores the changing terrain of Kakadu National Park. Lin has returned in the wet season to see plains in full flood, encounter crocodiles and learn about the indigenous culture hidden within the rocky escarpment. It is some of Australia's wildest and most beautiful countryside. The Northern Territory (aka NT) is a vast federal territory in Australia famed for its Outback desert landscapes. In the arid Red Centre lie the iconic sandstone monolith Uluru (Ayers Rock), the red-rock domes of Kata Tjuta and the sculpted cliffs of Kings Canyon in Watarrka National Park. Remote Alice Springs, the gateway town to the Red Centre desert, offers Aboriginal art galleries. The Northern Territory is bounded by the Timor and Arafura seas to the north and by Western Australia to the west, Queensland and the Gulf of Carpentaria to the east, and South Australia to the south. It is approximately 1,000 miles (1,600 km) from north to south and 600 miles (970 km) from east to west and occupies more than one-sixth of the Australian landmass. It is largely tropical in the north and semiarid in the far south. Constitutionally, the territory was inferior in status to the states until 1978, and it had limited legislative powers until self-government was granted in that year. Its development since 1911, when it was transferred to the Commonwealth of Australia from South Australia, has been a major item of expenditure in terms of works, services, and inducements to producers to accept the risks of an uncertain physical and economic environment. The nature of the climate, the poor soils, distance from assured markets, and problems of recruiting labour have been considerable handicaps. Nevertheless, increased mining activity in the early 21st century significantly strengthened the economy. Moreover, since the end of the 20th century the population of the Northern Territory has become one of the fastest-growing in the country; most residents are concentrated in and around the capital city, Darwin. Area 520,902 square miles (1,349,129 square km). Population (2011) 211,945.
