Geography of Australia

So you want to know all about Australian geography? You are in the right time and place! Here we go! The geography of an island, continent and a country Australia, being the world's smallest continent but the sixth-largest country in the world, contains a wide range of biogeographic regions. The population of Australia is concentrated along the eastern and southeastern coasts. The geography of the country is extremely diverse, ranging from the snow capped mountains of Tasmania to large deserts, tropical and temperate forests. Neighbouring countries include Indonesia, East Timor and Papua New Guinea to the north, the Solomon Islands, Vanuatu and the French dependency of New Caledonia to the northeast, and New Zealand to the southeast.

Australia's landmass of 7,617,930 square kilometres (2,941,300 sq mi) 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) 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.

It is interesting and very useful to know that The Great Barrier Reef, the largest coral reef in the whole world, lies a short distance off the northeast coast and extends for over 2,000 kilometres (1,240 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).

Going further, the largest part of Australia is desert or semi-arid lands normally known as the outback, the 40% of the landmass is covered by sand dunes. Australia is the flattest continent, with the oldest and least fertile soils, and is the driest inhabited continent. Only the southeast and southwest corners of the continent have a temperate climate. Most of the population lives along the temperate southeastern 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. In June 2008 it became known that an expert panel had warned of long term, maybe irreversible, severe ecological damage for the whole Murray-Darling basin if it does not receive sufficient water by October. Water restrictions are currently in place in many regions and cities of Australia in response to chronic shortages resulting from drought. As a final point of this topic, the Australian of the Year 2007 environmentalist Tim Flannery predicted that unless it made drastic changes, Perth in Western Australia could become the world’s first ghost metropolis, an abandoned city with no more water to sustain its population.
