In land area, Australia is the sixth largest nation after Russia, Canada, China, the United States of America and Brazil. It has, however, a relatively small population.
Australia is the only nation to govern an entire continent and its outlying islands. The mainland is the largest island and the smallest, flattest continent on Earth. It lies between 10° and 39° South latitude.
Australia is the driest inhabited continent on earth. Its interior has one of the lowest rainfalls in the world and about three-quarters of the land is arid or semi-arid. Its fertile areas are well-watered, however, and these are used very effectively to help feed the world. Sheep and cattle graze in dry country, but care must be taken with the soil. Some grazing land became desert when the long cycles that influence rainfall in Australia turned to drought.
Australia has a remarkable diversity of life forms seen nowhere else in the world. Australian plants and animals evolved in isolation from other parts of the world. When the super-continent of Gondwanaland split up about 160 million years ago, Australia joined Antarctica and drifted towards the South Pole, where glaciers formed a barrier between it and other land masses.
As the world climate warmed and glaciers melted, oceans graally rose to their current level and the land bridges to New Guinea and Tasmania were cut. Corals colonised a flooded coastal plain, forming the Great Barrier Reef of Queensland.
Pressure on native habitats from agriculture and introced pests like the fox and rabbit have resulted in extinctions of some native species in the past 200 years. Australia now has a strong scientific and legal framework to deal with these issues. Australians care about their unique environment.
