The landscapes of the Top End and the Gulf Country—with their tropical climate—include forest, woodland, wetland, grassland, rainforest and desert. At the north-west corner of the continent are the sandstone cliffs and gorges of The Kimberley, and below that the Pilbara. The Victoria Plains tropical savanna lies south of the Kimberly and Arnhem Land savannas, forming a transition between the coastal savannas and the interior deserts. At the heart of the country are the uplands of central Australia. Prominent features of the centre and south include Uluru (also known as Ayers Rock), the famous sandstone monolith, and the inland Simpson, Tirari and Sturt Stony, Gibson, Great Sandy, Tanami, and Great Victoria deserts, with the famous Nullarbor Plain on the southern coast. The Western Australian mulga shrublands lie between the interior deserts and Mediterranean-climate Southwest Australia.
