For anyone interested in the "critical" aspect mentioned by h0l0cube, please consider also reading "Farmers or Hunter-Gatherers? The Dark Emu Debate" by Peter Sutton and Keryn Walshe.
Peter Sutton is an anthropologist and linguist (>50 years); Keryn Walshe is an archaeologist (>35 years). Peter Sutton in particular has spent large amounts of time living with indigenous people in the far north. Their book describes many deficiencies in Dark Emu, and also gives a huge amount of interesting information about how aboriginal people lived, and the way they curated the land and the food resources available to them.
