The Strategic and Defence Studies Centre (SDSC) is a university-based institute that is situated in the Coral Bell School of Asia Pacific Affairs at the Australian National University. It is Australia's oldest-established centre for the study of strategic, defence and wider security issues and a leading regional think tank on these topics. The centre was established in 1966 by Professor T.B. Millar, then a senior fellow at the ANU's Department of International Relations, in order to "advance the study of Australian, regional, and global strategic and defence issues". The current head of SDSC is Brendan Taylor. Previous Heads include Emeritus Professor Paul Dibb and Professor Hugh White, who both also served as the Deputy Secretary for Strategy and Intelligence of the Department of Defence.
