The most diverse country of Oceania when it comes to the environment is Australia, with tropical rainforests in the north-east, mountain ranges in the south-east, south-west and east, and dry desert in the centre. Desert or semi-arid land commonly known as the outback makes up by far the largest portion of land. The coastal uplands and a belt of Brigalow grasslands lie between the coast and the mountains, while inland of the dividing range are large areas of grassland. The northernmost point of the east coast is the tropical-rainforested Cape York Peninsula.
