With most areas lying to the north of the Tropic of Capricorn, the Northern Territory stretches for 1610 km from north to south and 934 km from east to west.

The 1650 km flat northern coastline is scattered with numerous inlets, bays and river estuaries. The many islands off the coast include Grotte Eylandt and Vanderlin Island in the Gulf of Carpentaria and Melville and Bathurst islands off the northwest coast.

Due south, the land rises to an interior tableland. The low inland is mostly semi-arid with vast tracts of claypan desert and sand dunes. The MacDonnell Ranges crossed central Australia along the Tropic of Capricorn.These ranges contain amazing geological formations such as the Simpson's Gap. The Olgas and Ayers Rock, southwest of Alice Springs, show sections of ancient mountain ranges. Australia has some of the oldest mountain ranges in the world - there aren't very tall as over centuries they had been eroded away by the climate. The barren Simpson desert lies to the south-western side.
