No. 285 Squadron was a Royal Australian Air Force (RAAF) training squadron. Controlled by No. 84 Wing, the squadron was formed in August 1999 to train the RAAF's Lockheed Martin C-130J Hercules aircrew and ground support staff. No. 285 Squadron did not control any flying aircraft but managed the flight simulator used for converting aircrew to the C-130Js operated by No. 37 Squadron. It was also allocated decommissioned Hercules airframes for training purposes, as well as flying aircraft from No. 37 Squadron when required. Throughout its existence, No. 285 Squadron was located at RAAF Base Richmond in the western suburbs of Sydney. The squadron was disbanded in December 2017.
