Australia's 7,617,930 square kilometres (2,941,299 sq. mi) landmass is on the Indo-Australian Plate. Surrounded by the Indian, Southern and Pacific oceans, Australia is separated from Asia by the Arafura and Timor seas. Australia has a total 34,218 kilometres (21,262 mi) of coastline (excluding all offshore islands) and claims an extensive Exclusive Economic Zone of 8,148,250 square kilometres (3,146,057 sq. mi). This exclusive economic zone does not include the Australian Antarctic Territory.

The Great Barrier Reef, the world's largest coral reef, lies a short distance off the north-east coast and extends for over 2,000 kilometres (1,250 mi). Mount Augustus claimed to be the world's largest monolith, 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. Australia is the flattest continent, has 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. Most 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 Nino southern oscillation, which is correlated with periodic drought, and the seasonal tropical low pressure system that produces cyclones in northern Australia.
