The exact date of the first human habitation of Australia is still a subject of considerable research. There is strong scientific evidence for a presence around 50,000 years ago, a period of massive ecological upheaval in Australia which is believed to be consistent with human colonisation. However, there is some speculation about considerably earlier arrivals, even as far as 100,000 or more years ago. These first Australians were the remote ancestors of the current Australian Aborigines, and arrived via land bridges and navigation of significant sea crossings from present-day Southeast Asia.

Australia's economic development was slow at first and based on the export of wool. This all changed with the discovery of gold in 1851 and mining has, overall, been the most important sector of the Australian economy. By the late 20th century, Australia had a prosperous Western-style mixed economy, with a per capita GDP on par with the four dominant Western European economies. In recent years, the Australian economy has been resilient in the face of global economic downturn, with steady growth. Rising output in the domestic economy has been offsetting the global slump, and business and consumer confidence remains robust. Australia's emphasis on reforms is another key factor behind the economy's strength. In the 1980s, the Labor Party, led by Prime Minister Bob Hawke and Treasurer Paul Keating, played a crucial role in modernizing Australia's economy.

The sharing of animal and plant species between adjacent parts of Australia, Papua New Guinea, and Papua and nearby Indonesian islands point to early land bridges closed when sea levels rose. The historically traditional movement of people between these places in primitive sailing craft for trade and fishing, point to the possibility of Arab and Chinese traders to the northern islands learning of and then visiting the shores of the southern continent from as early as the 9th century. Maps compiled in Europe from the late 1400s show parts of the coastline.

The most popular spectator sport in Perth is Australian Rules football. Two teams in the Australian Football League (AFL) are based in Perth: the West Coast Eagles and the Fremantle Football Club (or "The Dockers").

To the visitor from the northern hemisphere, many of Australia's birds will immediately seem familiar - Australian wrens look and act very like northern hemisphere wrens, Australian robins seem to be close relatives of the northern hemisphere robins - but in fact the majority of Australian passerine birds are descended from the ancestors of the crow family, and the close resemblance is misleading: the cause is not genetic relatedness but convergent evolution.

Australian language is contradictory: it combines a mocking disrespect for established authority, particularly if it is pompous or out of touch with reality, with a distinctive upside-down sense of humour. For instance, Australians take delight in dubbing a tall man "Shorty", a silent one "Rowdy" a bald man "Curly", and a redhead, of course, is "Blue".

Alice Springs is best known outside the region as the setting of the Nevil Shute novel A Town Like Alice, and because of its proximity to Uluru, formerly known as Ayers Rock, the monolithic hill that is one of Australia's best-known natural landmarks as well as an important focus of Aboriginal culture and beliefs.

Chinese and Asian restaurants provide eat-in and takeaway services, and once again they cover the gamut from Europeanised 'faux' Asian food (soggy sweet-and-sour chicken) to the authentic. Most Australians prefer the genuine article, and the number of high-quality Asian restaurants is increasing.

Much of Australia's culture is derived from European and more recently American roots, but distinctive Australian features have evolved from the environment, aboriginal culture, and the influence of Australia's neighbours. The vigor and originality of the arts in Australia—films, opera, music, painting, theater, dance, and crafts—are achieving international recognition.
