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/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 many normal 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.
