Bush tucker, also called bush food, is any food native to Australia and historically eaten by Indigenous Australians, the Aboriginal and Torres Strait Islander peoples, but it can also describe any native flora, fauna, or funga used for culinary or medicinal purposes, regardless of the continent or culture. Animal native foods include kangaroo, emu, witchetty grubs and crocodile, and plant foods include fruits such as quandong, kutjera, spices such as lemon myrtle and vegetables such as warrigal greens and various native yams.
Traditional Indigenous Australians' use of bushfoods has been severely affected by the settlement of Australia in 1788 and subsequent settlement by non-Indigenous peoples. The introduction of non-native foods, together with the loss of traditional lands, resulting in reduced access to native foods by Aboriginal people, and destruction of native habitat for agriculture, has accentuated the reduction in use.
Since the 1970s, there has been recognition of the nutritional and gourmet value of native foods by non-Indigenous Australians, and the bushfood industry has grown enormously. Kangaroo meat has been available in supermarkets since the 1980s, and many other foods are sold in restaurants or packaged as gourmet foods, which has led to expansion of commercial cultivation of native food crops.
Aboriginal Australians have eaten native animal and plant foods for an estimated 60,000 years of human habitation on the Australian continent, using various traditional methods of processing and cooking. An estimated 5,000 species of native food were used by Aboriginal peoples. With much of it unsafe or unpalatable raw, a variety of methods were employed to render the various foods edible, such as cooking on open fires (meat) or boiling in bark containers. They would pound vegetables and seeds, or hang them in bags in running water.
Bush tucker provided a source of nutrition to the non-indigenous colonial settlers, often supplementing meagre rations.
