Dark Emu puts forward an argument for a reconsideration of the hunter-gatherer tag for pre-colonial Aboriginal Australians. The evidence insists that Aboriginal people right across the continent were using domesticated plants, sowing, harvesting, irrigating, and storing -- behaviours inconsistent with the hunter-gatherer tag. Gerritsen and Gammage in their latest books support this premise but Pascoe takes this further and challenges the hunter-gatherer tag as a convenient lie. Almost all the evidence in Dark Emu comes from the records and diaries of the Australian explorers, impeccable sources.

Bruce's comments on his book compared to Gammage's: " My book is about food production, housing construction and clothing, whereas Gammage was interested in the appearance of the country at contact. [Gammage] doesn't contest hunter gatherer labels either, whereas that is at the centre of my argument."
