Australian cuisine refers to the cuisine of Australia and its indigenous and colonial societies. Indigenous Australians have occupied these lands for some 40,000–60,000 years, during which time they developed a unique hunter-gatherer diet, known as "bush tucker", drawn from regional Australian flora and fauna—such as the kangaroo. Australia was, from 1788 to 1900, a collection of British colonies in which culinary tastes were strongly influenced by British and Irish traditions - and agricultural products such as beef cattle, sheep and wheat became staples in the Australian diet. Post-war Australia's multicultural immigration program lead to a diversification of the cuisine of Australia, particularly under the influence of Mediterranean and East Asian migrants.[1]
