The three main factors that contribute to Australia's demographic makeup are a diverse Aboriginal and Torres Strait Islander population, a British colonial past, and extensive immigration from many different countries and cultures. New Zealand is the national culture most closely related to Australia. New Zealanders have special rights of entry and there have been large population flows in both directions. Australians and New Zealanders compete vigorously in areas such as sports, but cooperate closely in international relations.
Many Australians are passionate about sports, which forms an important part of the country's culture in terms of spectators and participation. Over time, the diverse dietary, cultural and lifestyle practices of immigrants have been absorbed into the mainstream Australian culture. The styles of music, dance, theater and oratory vary significantly, reflecting the multicultural mix of society. Contemporary Australia is also a culture deeply influenced by global movements of meaning and communication, including advertising culture.
The intergenerational reproduction of ethnic minority identities has produced a multicultural, polyethnic and cosmopolitan national culture. Native Aboriginal people are a proud race and still practice ancient cultural aspects of tribal life, such as dancing, music, art, and even hunting. One aspect of the culture of companionship in language is that Australians have a propensity for diminutive forms of names. For example, the strong sense of social and historical distinction between different states and territories has not turned into a great subcultural diversity based on geographical regions.
Indigenous culture is still prevalent in many parts of the country, and tourists can easily find tour packages to learn more. The new code won and has maintained a greater number of followers in Australia than rugby union, which remained an amateur until the 1990s. The relatively sunny climate has facilitated the image of a sporting, outdoor and beach-loving culture represented by images such as that of the tanned Australian surfer. Australia's culture is primarily a Western culture, originally derived from Great Britain, but also influenced by the unique geography of Australia and the cultural contribution of Aboriginal people, Torres Strait Islanders, and other Australian peoples.
Other notable competitions include the annual Bledisloe Cup, which is played against Australia's main rivals, the New Zealand All Blacks, and the Rugby Championship, in which South Africa, New Zealand and Argentina participate. The contact between indigenous Australians and the new settlers varied from friendliness to violent conflict, but the diseases brought by the Europeans were devastating to Aboriginal populations and culture. Australia is a highly multicultural society with a strong mix of indigenous groups, individuals with European historical roots and a diverse mix of immigrant populations. Increasingly, works by Aboriginal authors and others from diverse cultural backgrounds are being published and appreciated.
