English is the main official and spoken language in Australia, although some of the surviving Aboriginal communities maintain their native languages.

By far the largest part of Australia is desert or semi-arid — 40% of the land mass is covered by sand dunes. Only the south-east and south-west corners have a temperate climate and moderately fertile soil. The northern part of the country has a tropical climate: part is tropical rainforests, part grasslands, and part desert. The Great Barrier Reef, the world's largest coral reef, lies a short distance off the north-east coast and extends for over 1,200 kilometres. Uluru (until 1986 known as Ayers Rock), is the second largest monolith in the world and is located in central Australia (the largest being Mount Augustus in Western Australia). The largest city in the world by area (not by population) is Mount Isa in northern Queensland.

Sydney boasts a full roster of musical, theatrical and artistic activity throughout the year, from the formal - including the Sydney Symphony Orchestra, the Sydney Theatre Company, the Sydney Dance Company, and the Archibald Prize - to festivals, including the Sydney Festival, a celebration of free performances throughout January. Many internationally known Australian rock bands have had their conception in Sydney, from Midnight Oil to INXS.

Immigration has been a major factor in Australia's development since the beginning of European settlement in 1788. For generations, most settlers came from Britain and Ireland, and the people of Australia are still predominantly of British or Irish origin, with a culture and outlook similar to that of the United Kingdom and the United States.

Although Australia was initially largely of British origin, and by the early 21st century was an overwhelmingly city-based society, receiving a large proportion of its cultural communication from either Hollywood and American TV networks, or home-grown productions that some claim are merely imitators.
