Bush tucker, also called bushfood, is any food native to Australia and used as sustenance by the original inhabitants, the Aboriginal Australians, but it can also describe any native fauna or flora used for culinary and/or medicinal purposes, regardless of the continent or culture. Examples of Australian native animal foods (meats) include kangaroo, emu and crocodile. In particular, kangaroo is quite common and can be found in Australian supermarkets, often cheaper than beef. Other animals, for example goanna and witchetty grubs, were eaten by Aboriginal Australians. Fish and shellfish are culinary features of the Australian coastal communities.
Examples of Australian native plant foods include the fruits quandong, kutjera, muntries, riberry, Davidson's plum, and finger lime. Native spices include lemon myrtle, mountain pepper, and aniseed myrtle. A popular leafy vegetable is warrigal greens. Nuts include bunya nut, and the most identifiable bush tucker plant harvested and sold in large-scale commercial quantities is the macadamia nut. Knowledge of Aboriginal uses of fungi is meagre but beefsteak fungus and native "bread" (a fungus also), were certainly eaten.
