Climatic zones in Australia, based on Köppen classification
Australia's landmass of 7,617,930 square kilometres (2,941,300 sq mi)[40] is on the Indo-Australian Plate. Surrounded by the IndianN4 and Pacific oceans, Australia is separated from Asia by the Arafura and Timor seas. Australia has 34,218 kilometres (21,262 mi) of coastline (excluding all offshore islands)[41] and claims an extensive exclusive economic zone of 8,148,250 square kilometres (3,146,060 sq mi). This exclusive economic zone does not include the Australian Antarctic Territory.
The Great Barrier Reef, the world's largest coral reef,[42] lies a short distance off the north-east coast and extends for over 2,000 kilometres (1,240 mi). Mount Augustus, claimed to be the world's largest monolith,[43] is located in Western Australia. At 2,228 metres (7,310 ft), Mount Kosciuszko on the Great Dividing Range is the highest mountain on the Australian mainland, although Mawson Peak on the remote Australian territory of Heard Island is taller at 2,745 metres (9,006 ft).
By far the largest part of Australia is desert or semi-arid lands commonly known as the outback. Australia is the flattest continent, with the oldest and least fertile soils, and is the driest inhabited continent. Only the south-east and south-west corners of the continent have a temperate climate. The population density, 2.8 inhabitants per square kilometre, is among the lowest in the world, although a great proportion of the population lives along the temperate south-eastern coastline. The landscapes of the northern part of the country, with a tropical climate, consist of rainforest, woodland, grassland, mangrove swamps, and desert. The climate is significantly influenced by ocean currents, including the El Niño southern oscillation, which is correlated with periodic drought, and the seasonal tropical low pressure system that produces cyclones in northern Australia.[44]
Climate change has become an increasing concern in Australia in recent years,[45] with many Australians considering it to be the most important issue facing the country.[46] The first Rudd Ministry has initiated several emission reduction activities;[47] Rudd's first official act, on his first day in office, was to sign the instrument of ratification of the Kyoto Protocol. Nevertheless Australia's carbon dioxide emissions per capita are among the highest in the world, lower than only several other industrialised nations including the United States, Canada, and Norway. Rainfall in Australia has increased over the past century, both nationwide and for all four quadrants of the nation.[48] Despite this beneficial effect of climate change, water restrictions are currently in place in many regions and cities of Australia in response to chronic shortages due to urban population increases and localised drought.[49]
