Australia - ôstrālˈyə, smallest continent, between the Indian and Pacific oceans. With the island state of
Tasmania to the south, the continent makes up the Commonwealth of Australia, a federal parliamentary state (1995 est. pop. 18,322,000), 2,967,877 sq mi (7,686,810 sq km). Australia's capital is
Canberra. Its largest city is
Sydney, closely followed in population by
Melbourne. There are five continental states in the nation (
Queensland,
New South Wales,
Victoria,
South Australia, and
Western Australia) as well as the
Northern Territory and the
Australian Capital Territory (an enclave within New South Wales, containing Canberra). Australia's external territories include Norfolk Island, Christmas Island, the Cocos (Keeling) Islands, and the Australian Antarctic Territory.
Land The Australian continent extends from east to west some 2,400 mi (3,860 km) and from north to south nearly 2,000 mi (3,220 km). It is on the whole exceedingly flat and dry. Less than 20 in. (50.8 cm) of precipitation falls annually over 70% of the land area. From the narrow coastal plain in the west the land rises abruptly in what, from the sea, appear to be mountain ranges but are actually the escarpments of a rough plateau that occupies the western half of the continent. It is generally from 1,000 to 2,000 ft (305–610 m) high but several mountain ranges rise to nearly 5,000 ft (1,520 m); there are no permanent rivers or lakes in the region. In the southwest corner of the continent there is a small moist and fertile area, but the rest of Western Australia is arid, with large desert areas. The northern region fronts partly on the Timor Sea, separating Australia from Indonesia; it also belongs to the plateau, with tropical temperatures and a winter dry season. Its northernmost section, Arnhem Land (much of which is an aboriginal reserve), faces the Arafura Sea in the north and the huge Gulf of Carpentaria on the east. On the eastern side of the gulf is the Cape York Peninsula, which is largely covered by woodland. Off the coast of NE Queensland is the Great Barrier Reef, the world's largest coral reef. In E Australia are the mountains of the Eastern Highlands, which run down the entire east and southeast coasts. The rivers on the eastern and southeastern slopes run to the Coral Sea and the Tasman Sea through narrow but rich coastal plains; the rivers on the western slopes flow either N to the Gulf of Carpentaria or W and SW to the Indian Ocean. The longest of all Australian river systems, the Murray River and its tributaries, drains the southern part of the interior basin that lies between the mountains and the great plateau. The rivers of this area are used extensively for irrigation and hydroelectric power. Australia, remote from any other continent, has many distinctive forms of plant life—notably species of giant eucalyptus—and of animal life, including the kangaroo, the koala, the flying opossum, the wallaby, the wombat, the platypus, and the spiny anteater; it also has many unusual birds. Foreign animals, when introduced, have frequently done well. Rabbits, brought over in 1788, have done entirely too well, multiplying until by the middle of the 19th cent. they became a distinct menace to sheep raising. In 1907 a fence (still maintained) 1,000 mi (1,610 km) long was built from the north coast to the south to prevent the rabbits from invading Western Australia. People Most Australians are of British and Irish ancestry and the majority of the country lives in urban areas. Its population has more than doubled since the end of World War II, spurred by an ambitious postwar immigration program. In the 19th cent., Australia enacted strong measures to prevent immigration by nonwhites. After World War II, immigration from Greece, Turkey, Italy, and other countries increased Australia's cultural diversity. In 1973, Australia officially ended discriminatory immigration policies, and substantial Asian immigration followed. By 1988 about 40% of immigration to Australia was from Asia, and by 1997 Asians constituted about 5% of the population. Nonetheless, there remains substantial anxiety among white Australians concerning Asian immigration. The indigenous population, the
Australian aborigines, estimated to number as many as 350,000 at the time of the Europeans' arrival, was numbered at 386,049 (including Torres Strait Islanders, who are of Papuan descent) in 1996. Although still more rural than the general population, the aboriginal population has become more urbanized, with some two thirds living in cities. New South Wales and Queensland account for just over half of the Australian aboriginal population. In Tasmania the aboriginal population was virtually wiped out in the 19th cent. There is no state religion in Australia. The largest churches are the Anglican and Roman Catholic. Although education is not a federal concern, government grants have aided in the establishment of state universities including the Univ. of Sydney (1852), the Univ. of Melbourne (1854), the Univ. of Adelaide (1874), and the Univ. of Queensland (in Brisbane, 1909). Economy Most of the rich farmland and good ports are in the east and particularly the southeast, except for the area around
Perth in Western Australia. Melbourne, Sydney,
Brisbane, and
Adelaide are the leading industrial and commercial cities. There has been considerable industrial development in the last two decades of the 20th cent., and the standard of living has remained generally high. While the Australian economy fell into a severe recession in the late 1980s, but experience an extended period of growth beginning in the 1990s, although it suffered somewhat from the Asian economic slump of the 1990s and from the drought of 2002–3. Australia is highly industrialized, and manufactured goods account for most of the gross domestic product. Its chief industries include mining (much of which is accomplished with the aid of Japanese capital), food processing, and the manufacture of industrial and transportation equipment, chemicals, iron and steel, textiles, machinery, and motor vehicles. Australia has valuable mineral resources, including coal, iron, bauxite, copper, tin, lead, zinc, and uranium; the country is an important producer of opals and diamonds. Some lumbering is done in the east and southeast. The country is self-sufficient in food, and the raising of sheep and cattle and the production of grain have long been staple occupations. Tropical and subtropical produce—citrus fruits, sugarcane, and tropical fruits—are also important, and there are numerous vineyards and dairy and tobacco farms. Australia maintains a favorable balance of trade. Its chief export commodities are metals, minerals, coal, wool and beef (of which it is the world's largest exporter), mutton, cereals, and manufactured products. The leading imports are manufactured raw materials, capital equipment, and consumer goods. Australia's economic ties with Asia and the Pacific Rim have become increasingly important. Government The executive power of the commonwealth is vested in a governor-general (representing the British sovereign) and a cabinet, presided over by the prime minister, which represents the party or coalition holding a majority in the lower house of parliament. The parliament consists of two houses. The distribution of federal and state powers is roughly like that in the United States. British intervention in Australian affairs was formally abolished in 1986. From its early years the federal government has been noted for its liberal legislation, such as woman suffrage (1902), old-age pensions (1909), and maternity allowances (1912). There are four main political parties: Liberal, Labor, National, and Democratic. History Early History and Colonization The groups comprising the aborigines are thought to have migrated from Southeast Asia. Skeletal remains indicate that aborigines arrived in Australia more than 40,000 years ago, and some evidence suggests that they were active there about 100,000 years ago. The aborigines spread throughout Australia and remained isolated from outside influences until the arrival of the Europeans. Australia was probably first sighted by a Portuguese, Manuel Godhino de Eredia, in 1601 and may have been sighted by a Spaniard, Luis Vaez de Torres, around 1605–6. It was later visited by the Dutch, who named it New Holland. In 1688 the Englishman William Dampier landed at King Sound on the northwest coast. Little interest was aroused, however, until the fertile east coast was observed when Capt. James Cook reached Botany Bay in 1770 and sailed N to Cape York, claiming the coast for Great Britain. In 1788 the first British settlement was made—a penal colony on the shores of Port Jackson, where Sydney now stands. By 1829 the whole continent was a British dependency. Exploration, begun before the first settlement was founded, was continued by such men as Matthew Flinders (1798), Count Paul Strzelecki (1839), Ludwig Leichhardt (1848), and John McDouall Stuart (first to cross the continent, 1862). Australia was long used as a dumping ground for criminals, bankrupts, and other undesirables from the British Isles. Sheep raising was introduced early, and before the middle of the 19th cent. wheat was being exported in large quantities to England. A gold strike in Victoria in 1851 brought a rush to that region. Other strikes were made later in the century in Western Australia. With minerals, sheep, and grain forming the base of the economy, Australia developed rapidly. By the mid-19th cent. systematic, permanent colonization had completely replaced the old penal settlements. Modern Australia Confederation of the separate Australian colonies did not come until a constitution, drafted in 1897–98, was approved by the British parliament in 1900. It was put into operation in 1901; under its terms, the colonies of New South |
