Australian culture is as broad and varied as the country's landscape. Australia is multicultural and multiracial and this is reflected in the country's food, lifestyle and cultural practices and experience. Australia has an important heritage from its indigenous people, which plays a defining role in the cultural landscape. This diversity of influences creates a cultural environment in Australia that is lively, energised, innovative and outward looking. Australia's population is concentrated along the coastal region of Australia from Adelaide to Cairns, with a small concentration around Perth, Western Australia. The center of Australia is sparsely populated.
