Noongar Bush Tucker: Bush Food Plants and Fungi of the South-West of Western Australia. Before the colonisation of Australia, Aboriginal Australians lived on a wonderful larder of fresh fruit, vegetables and lean meat, in a land largely free from disease, with more exercise, less stress and supportive communities. Today, in Aboriginal communities all over Australia, there are higher instances of heart disease, type 2 diabetes, renal disease, some types of cancer and lung diseases than in the general population.
