In 1970, the Roulettes were formed to celebrate the RAAF's 50th anniversary to be held throughout the year of 1971. The Roulettes first air show was at Point Cook in Dec 1970. Their last air show using the Macchi was at Lakes Entrance in June 1989. Initially, they were equipped with four Macchis, growing to five aircraft in 1974 and seven in 1981 before cost-cutting saw the team reduced to five again in 1982. Towards the end of the 1980s, the Roulettes flying hours had to be reduced as the MB-326 fleet developed premature metal fatigue problems and a replacement aircraft type was investigated. In 1989, with the new Pilatus PC-9 trainers starting to arrive and MB-326 airframe hours severely limited, the Roulettes flew just a single pair of Macchis. The Roulettes switched over to the new PC-9s in late 1989, and arrived at the composition they have used ever since: six PC-9s plus a spare.
