Australia is the world's smallest continent and largest island, a relatively young nation established in an ancient land. Its development represents a triumph(胜利)over remoteness and a harsh landscape.

It is generally accepted that Australia's original inhabitants, the aboriginal(土著的)people, have lived on the continent for 40,000 to 60,000 years. They were also its sole(唯一的)human inhabitants until two centuries ago. Indonesian traders probably visited Australia's northwest but it was unknown to the rest of the world until the 1600s. A huge south land appeared on maps before 200 AD but its existence was not confirmed until the 17th century when Portuguese, Spanish and Dutch merchants ventured into Asia.

The first European settlement of the continent--by the British--began in 1788, on the site now occupied by Sydney, Australia's largest city. There were then about 1500 Europeans and an estimated 300,000 aboriginal people in Australia. The population has reached 2.25 million by 1881, 5.41 million by 1921 and 7.4 million by the end of World War II(1945). It increased sharply, partly because of a large postwar immigration program, and reached more than 17 million in 1991, despite a decline that began in the 1970s in the natural increase and net immigration. The rate of population increase in the 40 years after world war II, about two percent, has halved.

Australia is one of the most urbanized countries in the world, with about 70 percent of the population living in the 10 largest cities. Australians have a high standard of living by world standards. The flag of Australia is the only one to fly over a whole continent in the world. The small Union Jack represents the historical link with Britain, the largest star has six points for each of the states and one point for the territories, and the small stars form. the Southern Cross - a prominent of the southern hemisphere night sky.
