There are many names for Australia - Oz, Down Under, and the official name,the Commonwealth of Australia, The first were convicts who had been transported from Britain. But after gold was discovered in the 1850s,thousands of free settlers left the cold,dark industrial towns of Britain to find their place in the sun. Australia has a population of about sixteen and a half million people.Over eighty per cent Australia's population is of British origin.However,in recent years most immigrants have come from other European countries such as Italy, Greece or Poland,or from Asian countries. English is the national language,cricket is the national game,and they drive on the left. Australia is a huge country and has a wide range of climates from the tropical rain forests of the Northern Territory and northern Queensland to the mild temperate climate of Victoria and Tasmania in the south east. About two-thirds of the land is desert or semi-desert.As a result most of the central and western parts of Australia are uninhabited or inhabited only by sheep.Australia has ten times as many sheep as people and is the world's largest producer of wool. Sydney,with its beautiful harbour, bridge and opera house, is the largest city, with three and a hall million inhabitants,but it isn't the capital.Australia is the federal state and, like the United States of America, it has a separate capital city - Canberra.The Head of Government is the Prime Minister, but the Head of State is still the British monarch. Mining, industry and agriculture are Australia's most important sources of income.More recently, tourism has become important, too.Tourists come to enjoy Australia's warm climate, to see the unique animals, such as the kangaroo and the koala.
