There is an article, “The Incidence of Cannibalism in Aboriginal Society” by William D. Rubinstein Quadrant Online 30th August 2021, which is behind a pay wall, but I don’t have access, and did not find any other link. I would presume that it is a discussion of the 19th century accounts of alleged Aboriginal cannibalism, as recorded by white explorers, and anthropologists of the time, but I can’t say what conclusions are reached. Some examples of the literature I have seen from someone who emailed me material from just the front piece of the cited article: P. Foelsche, “Notes on the Aborigines of North Australia”, in Transactions of the Royal Society of South Australia, vol. 5, 1882, and Rev. Louis Schulze, missionary, “The Aborigines of the Upper and Middle Finke River: Their Habits and Customs”, in Transactions of the Royal Society of South Australia, vol. 14, 1891, which details the alleged cannibalism of some infants. There are many other depictions of this practice from 19th century accounts.
