Chief of Air Force (CAF) is the most senior appointment in the Royal Australian Air Force (RAAF), responsible to the Chief of the Defence Force (CDF) and the Secretary of the Department of Defence. The rank associated with the position is air marshal (three-star). The role encompasses "the delivery of aerospace capability, enhancing the Air Force's reputation and positioning the Air Force for the future". It does not include direction of air operations, which is the purview of the Air Commander Australia, a two-star position responsible directly to CDF in such circumstances but nominally reporting to CAF.
