A Cautious Silence is about the establishment of anthropology as an academic and applied discipline in Australia from about 1920 until after World War II. During this period, anthropological research in Australia largely focused on indigenous Australia, New Guinea, Papua and some Pacific islands. A signal event marking the beginning of the period covered in the book was the foundation in 1921 of the Australian (rather than British) National Research Council (ANRC). Marking the end were the debates over the establishment of the Woomera Rocket Range and the consequences for Aborigines in the region. Geoffrey Gray’s afterword deals briefly with university and research politics in the 1950s and 1960s.
