Australia, officially the Commonwealth of Australia, is a country in the southern hemisphere. It comprises the mainland of the world’s smallest(36)continent, the major island of Tasmania, and(37)numerous other islands in the Indian and Pacific Oceans. And it also has many(38)neighboring countries.
    For around 40,000 years before European(39)settlement commenced in the late 18th century, the Australian mainland and Tasmania were(40)inhabited by around 250 individual nations of local Australians. After(41)scattered visits by fishermen from the north, and European discovery by Dutch explorers in 1606, the eastern half of Australia was(42)claimed by the British in 1770 and(43)claimed settled in the colony of New South Wales, founded on 26 January 1788.(44)The population grew steadily in the following years and the continent was explored thorough-ly. During the 19th century another five largely self-governing Crown Colonies were established.
    Since the six colonies became a federation and the Commonwealth of Australia was formed,(45)Australia has maintained a stable liberal democratic political system and remains a Commonwealth realm. The population is just over 21. 3 million, with about 60% concentrated in and around the mainland state capitals of Sydney, Melbourne, etc.
    Technologically advanced and industrialized,(46)Australia is a prosperous multicultural country and has good results in many international comparisons of national performance, such as health care, public education, economic freedom, and the protection of civil liberties and political rights.
