This series consists of case files compiled by the Investigation Branch and from 1946, the Commonwealth Investigation Service. Matters dealt with include illegal immigrants, bankrupts, internees, prisoners of war, fraud against the Commonwealth. Dossiers were compliled for individuals, companies and organisations.
It is not known precisly when this series commenced, but it is believed to be about 1920. This series underwent a massive degree of top numbering, both within the series, and from other series (notably SP26/1, Dossiers on Internees, single number series). In addition a large number of items from this series were handed over to A.S.I.O. following the establishment of that agency in 1949. A list of these files is given in ST2476/11.
