The index to the Aboriginal War Census returns 1915-1916 is now available at the Queensland State Archives web site. This series is described as follows
"A census of the Australian population was conducted during the First World
War. The Chief Protector of Aboriginals wrote to each district officer under his
control requesting a census of the Aboriginal population in accordance with the
national census requirements. Lists of Aboriginal people living at various
settlements to be used for war census purposes resulted. Many district officers
not only listed all men aged from 18 to 45 years for war purposes, but also
included all women and children and residents of other ethnic backgrounds such
as South Sea Islanders and Rotumans.
Entries in the index are linked to the original registers namely Series ID 4354, Miscellaneous Items and Correspondence, specifically Item ID 716223, Papers, 1915-1916.
