The Australian Defence College combines the Australian War College, the Australian Defence Force Training Centre and the Australian Defence Force Academy and supporting Centres of Excellence. In 2019, the Australian Defence College implemented its biggest organisational reform in almost two decades. The changes included the amalgamation of the Centre for Defence and Strategic Studies and the Australian Command and Staff College to form the Australian War College, to focus on Joint Professional Military Education. Individual training delivered by the Australian Defence Force Warfare Training Centre, Peace Operations Training Centre, Defence Force Chaplains College, Defence International Training Centre, and Defence Force School of Languages was centralised in the Australian Defence Force Training Centre.
