From time to time, the CO of an RAAF operational squadron recommends a pilot for instructor duties with either the Basic Flying Training School at Tamworth, NSW or at 2 Flying Training School at Pearce, WA. Upon progression through several levels of instructor categorisation, some of these pilots are then selected for duty at the Central Flying School, where they train flying instructors. From the 21 CFS senior instructors, the CFS commanding officer and the Roulette leader then offer selected individuals a chance to try out for the Roulettes. The team is organised in 'seasons' lasting six months; most members serve on the team for three seasons before moving on to other duties.
