Darwin is the capital city of the Northern Territory, Australia. Situated on the Timor Sea, Darwin is the largest city in the sparsely populated Northern Territory, with a population of 136,245. It is the smallest and most northerly of the Australian capital cities, and acts as the Top End's regional centre. Darwin was originally a pioneer outpost.Darwin's proximity to South East Asia makes it an important Australian gateway to countries such as Indonesia and East Timor. The Stuart Highway begins in Darwin, ending at Port Augusta in South Australia. The city itself is built on a low bluff overlooking the harbour. Its suburbs spread out over some area, beginning at Lee Point in the north and stretching to Berrimah in the east. Past Berrimah, the Stuart Highway goes on to Darwin's satellite city, Palmerston, and its suburbs. The region, like the rest of the Top End, has a tropical climate, with a wet and a dry season. The city is noted for its consistently warm to hot climate, all throughout the year. Prone to cyclone activity during the wet season, Darwin experiences heavy monsoonal downpours and spectacular lightning shows. During the dry season, the city is met with blue skies and gentle sea breezes from the picturesque harbour.
