An article that was mentioned briefly before in these pages, needs to be remembered: https://cairnsnews.org/2015/09/25/dreamtime-a-cruel-delusion-of-british-anthropologists/. The article makes the argument that following anthropologist Alfred Cort Haddon’s book, The Races of Man (1909), the Aborigines are likely to be new comers, compared to a Negrito people who allegedly originally inhabited the country. Pre-1770 explorers such as William Dampier who visited West and Northern Australia in the late 1600s saw these people. He described a race of people with hair “curled like the Negroes,” which the modern Aborigine does not have. The Aborigines may displaced them, for where else could they have gone?
Anyone supporting this theory will need to address arguments such as that given by R. Tobler (et al.), “Aboriginal Mitogenomes Reveal 50,000 Years of Regionalism in Australia,” Nature, (2017); doi:10.1038/nature21416, which allegedly found “evidence for the continuous presence of populations in discrete geographic areas dating back to around 50 [thousand years], in agreement with the notable Aboriginal Australian cultural attachment to their country.”
