Officer Training Unit, Scheyville

The Officer Training Unit, Scheyville (OTU Scheyville, pronounced Skyville) was a military training establishment for officers of the Australian Army. Located in the area of Scheyville in the Hawkesbury region of Sydney, Australia, the establishment was opened in April 1965 to train officer cadets who had been called up for service under the national service scheme and offered a short but rigorous commissioning course for trainees, tailored to meet the Army's need to increase the number of junior officers being produced in order to meet commitments to train national servicemen, and to provide platoon commanders for units serving overseas in Vietnam and other parts of Southeast Asia.
