Aboriginal Traditional Diet A major food item for Aborigines: Tasmanian wallabies (ALMFA, SLT) Over the past 30, 000 years, dramatic changes in climate, and hence food resources, occurred in Tasmania. Indigenous peoples successfully adapted their food resource management to cope with those changes, for example, using fire to modify the vegetation. On the eve of British settlement/invasion, key foods of animal origin included kangaroo and wallaby, possum and wombat, muttonbird and penguins (both the flesh and the eggs) and various molluscs and crustacea. Their plant menu included fruits such as the native cherry, native currant and kangaroo apple, and vegetables such as the native potato and native carrot. (The adjective 'native' emphasises that these were quite different species from their European namesakes. ) They also ate plants unfamiliar to later Tasmanians, such as honeysuckle nectar, pith from manferns, and the 'native bread' fungus. The fermented sap of the cider gum apparently provided a weakly alcoholic beverage, used occasionally.
"Our results suggest that, rather than having left in a separate wave, most of the genomes of Papuans and Aboriginal Australians can be traced back to a single 'Out of Africa' event which led to modern worldwide populations, " said Manjinder Sandhu, a senior author from the Sanger Institute and University of Cambridge, in a statement released by the university. "There may have been other migrations, but the evidence so far points to one exit event. " Around 50, 000 years ago, the wave of migration reached Sahul, a prehistoric supercontinent composed of present-day Australia, Tasmania and New Guinea prior to their separation by rising sea levels 10, 000 years ago. At that time, according to the study's authors, Aboriginal Australians became genetically isolated, making it the world's oldest civilization. Aboriginal hunter in the Australian Outback.

Other significant barriers were poor oral health and depression, the higher cost of healthier food and generational food preferences. Conclusion: Aboriginal cooking course participants faced multiple barriers to dietary change - social, financial, medical and historical. The family was the most crucial determinant of participant ability to achieve sustained dietary change.
