Australia

Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the largest country in Oceania and the world’s sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. Australia’s capital is Canberra, and its largest city is Sydney.

The name Australia is derived from the Latin Terra Australis (“southern land”), a name used for a hypothetical continent in the Southern Hemisphere since ancient times.

For about 50,000 years before the first British settlement in the late 18th century, Australia was inhabited by indigenous Australians

After the European discovery of the continent by Dutch explorers in 1606, Australia’s eastern half was claimed by Great Britain in 1770 and initially settled through penal transportation to the colony of New South Wales from 26 January 1788. The population grew steadily in subsequent decades, and by the 1850s most of the continent had been explored and an additional five self-governing crown colonies established. On 1 January 1901, the six colonies federated, forming the Commonwealth of Australia.

Australia has since maintained a stable liberal democratic political system that functions as a federal parliamentary constitutional monarchy comprising six states and several territories. Australia has the world’s 13th-largest economy and tenth-highest per capita income (IMF). Australia is a member of the United Nations, G20, Commonwealth of Nations, ANZUS, Organisation for Economic Co-operation and Development (OECD), World Trade Organization, Asia-Pacific Economic Cooperation, and the Pacific Islands Forum. The population of 25 million is highly urbanised and heavily concentrated on the eastern seaboard. Australia has the world’s 9th largest immigrant population, with immigrants accounting for 26% of the population.

Pre-colonial history

Aboriginal rock art in the Kimberley region of Western Australia. Human habitation of the Australian continent is estimated to have begun around 65,000 to 70,000 years ago, with the migration of people by land bridges and short sea-crossings from what is now Southeast Asia. These first inhabitants were the ancestors of modern Indigenous Australians.

At the time of European settlement in the late 18th century, most Indigenous Australians were hunter-gatherers with complex economies and societies. Indigenous Australians have an oral culture with spiritual values based on reverence for the land and a belief in the Dreamtime. The Torres Strait Islanders, ethnically Melanesian, obtained their livelihood from seasonal horticulture and the resources of their reefs and seas. The northern coasts and waters of Australia were visited sporadically by fishermen from Maritime Southeast Asia.

European Arrival

The first ship and crew to chart the Australian coast and meet with Aboriginal people was the Duyfken captained by Dutch navigator, Willem Janszoon. He sighted the coast of Cape York Peninsula in early 1606, and made landfall on 26 February at the Pennefather River near the modern town of Weipa on Cape York.

Characteristics

Australia’s landmass of 7,617,930 square kilometres (2,941,300 sq mi) is on the Indo-Australian Plate. Surrounded by the Indian and Pacific oceans, it is separated from Asia by the Arafura and Timor seas, with the Coral Sea lying off the Queensland coast, and the Tasman Sea lying between Australia and New Zealand. The world’s smallest continent and sixth largest country by total area, Australia—owing to its size and isolation—is often dubbed the “island continent” and is sometimes considered the world’s largest island. Australia has 34,218 kilometres (21,262 mi) of coastline (excluding all offshore islands) and claims an extensive Exclusive Economic Zone of 8,148,250 square kilometres (3,146,060 sq mi).

The Great Barrier Reef, the world’s largest coral reef,lies a short distance off the north-east coast and extends for over 2,000 kilometres (1,240 mi). Mount Augustus, claimed to be the world’s largest monolith, is located in Western Australia. At 2,228 metres (7,310 ft), Mount Kosciuszko on the Great Dividing Range is the highest mountain on the Australian mainland. Even taller are Mawson Peak (at 2,745 metres or 9,006 feet), on the remote Australian territory of Heard Island, and, in the Australian Antarctic Territory, Mount McClintock and Mount Menzies, at 3,492 metres (11,457 ft) and 3,355 metres (11,007 ft) respectively.

Climate

The climate of Australia is significantly influenced by ocean currents, including the Indian Ocean Dipole and the El Niño–Southern Oscillation, which is correlated with periodic drought, and the seasonal tropical low-pressure system that produces cyclones in northern Australia. These factors cause rainfall to vary markedly from year to year. Much of the northern part of the country has a tropical, predominantly summer-rainfall (monsoon). The south-west corner of the country has a Mediterranean climate. The south-east ranges from oceanic (Tasmania and coastal Victoria) to humid subtropical (upper half of New South Wales). The interior is arid to semi-arid.

Biodiversity

Although most of Australia is semi-arid or desert, it includes a diverse range of habitats from alpine heaths to tropical rainforests, and is recognised as a megadiverse country. Fungi typify that diversity; an estimated 250,000 species—of which only 5% have been described—occur in Australia. Because of the continent’s great age, extremely variable weather patterns, and long-term geographic isolation, much of Australia’s biota is unique. About 85% of flowering plants, 84% of mammals, more than 45% of birds, and 89% of in-shore, temperate-zone fish are endemic.

Australia has the greatest number of reptiles of any country, with 755 species. Besides Antarctica, Australia is the only continent that developed without feline species. Feral cats may have been introduced in the 17th century by Dutch shipwrecks, and later in the 18th century by European settlers. They are now considered a major factor in the decline and extinction of many vulnerable and endangered native species.

Culture

Since 1788, the primary influence behind Australian culture has been Anglo-Celtic Western culture, with some Indigenous influences. The divergence and evolution that has occurred in the ensuing centuries has resulted in a distinctive Australian culture. Since the mid-20th century, American popular culture has strongly influenced Australia, particularly through television and cinema. Other cultural influences come from neighbouring Asian countries, and through large-scale immigration from non-English-speaking nations.

Sport and recreation

The Melbourne Cricket Ground is strongly associated with the history and development of cricket and Australian rules football, Australia’s two most popular spectator sports. About 24% of Australians over the age of 15 regularly participate in organised sporting activities.

Australia is unique in that it has professional leagues for four football codes. Australian rules football, the world’s oldest major football code and Australia’s most popular sport in terms of revenue and spectatorship, originated in Melbourne in the late 1850s, and predominates in all states except New South Wales and Queensland, where rugby league holds sway, followed by rugby union. Soccer, while ranked fourth in popularity and resources, has the highest overall participation rates.

Australia is one of five nations to have participated in every Summer Olympics of the modern era and has hosted the Games twice: 1956 in Melbourne and 2000 in Sydney. Australia has also participated in every Commonwealth Games, hosting the event in 1938, 1962, 1982, 2006 and will host the 2018 Commonwealth Games.
