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. The population of 25 million is highly urbanised and heavily concentrated on the eastern seaboard. Australia's capital is Canberra, and its largest city is Sydney. The country's other major metropolitan areas are Melbourne, Brisbane, Perth and Adelaide.

Australia was inhabited by indigenous Australians for about 60,000 years before the first British settlement in the late 18th century. It is documented that Aborigines spoke languages that can be classified into about 250 groups. After the European exploration of the continent by Dutch explorers in 1606, who named it New Holland, 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, a date which became Australia's national day. 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 ten territories.

Being the oldest, flattest and driest inhabited continent, with the least fertile soils, Australia has a landmass of 7,617,930 square kilometres (2,941,300 sq mi). A megadiverse country, its size gives it a wide variety of landscapes, with deserts in the centre, tropical rainforests in the north-east and mountain ranges in the south-east. A gold rush began in Australia in the early 1850s, which boosted the population of the country. Nevertheless, its population density, 2.8 inhabitants per square kilometre, remains among the lowest in the world. Australia generates its income from various sources including mining-related exports, telecommunications, banking and manufacturing. Indigenous Australian rock art is the oldest and richest in the world, dating as far back as 60,000 years and spread across hundreds of thousands of sites.

Male Fairy-wren in breeding plumage

The Variegated Fairy-wren (Malurus lamberti) is a fairy-wren that lives in diverse habitats spread across most of Australia. Four subspecies are recognised. The brightly coloured breeding male has chestnut shoulders and blue crown and ear coverts, while non-breeding males, females and juveniles have predominantly grey-brown plumage. Notably, females of the two subspecies rogersi and dulcis (previously termed Lavender-flanked Fairy-wren) have mainly blue-grey plumage.

Like other fairy-wrens, the Variegated Fairy-wren is a cooperative breeding species, with small groups of birds maintaining and defending small territories year-round. Groups consist of a socially monogamous pair with several helper birds who assist in raising the young. Male wrens pluck yellow petals and display them to females as part of a courtship display. These birds are primarily insectivorous and forage and live in the shelter of scrubby vegetation across 90% of continental Australia, which is a wider range than that of any other fairy-wren.

The Australian wine industry is the fourth largest exporter in the world, exporting over 400,000,000 litres a year to a large international export market that includes "old world" wine-producing countries such as France, Italy and Spain.
