History of the bushfood industry
The modern Australian native food industry, also called the bushfood industry, had its initial beginnings in the 1970s and early 1980s, when regional enthusiasts and researchers started to target local native species for use as food. Indigenous Australians had been harvesting many species for use as food (bush tucker) and medicines (bush medicine) for millennia.
