The Royal Australian Air Force believed in training recruits to high standards instilling in them Service Knowledge, Arms Skills, Drill and Teammanship.
It was the Instructors job to take a bunch of raw recruits and turn them into Airmen. They were known as Drill Instructors, Course Corporals and a few unsavoury names.
In the beginning around 1952 when RTU started, they was a Mustering titled "Drill Instructors" then Airfield Defence Guards took over the roll and in later years General Service Instructors were introduced to bring RAAF members out of normal Musterings for a stint as a "GSI" or as they are known as now "MSI" Military Skills Instructor, on a time rotational posting to 1RTU. Many other Officer Branches & Musterings served at 1RTU including WOD, Clerk Admin, Clerk Supply, Supplier, Fireman, and PTI to name a few.
