The Roulettes are the Royal Australian Air Force's aerobatic demonstration team. They were formed in 1970 following the success of their predecessor teams, Red Sales and Telstars. Les Roulettes had their first public display at RAAF Base Point Cook in 1970. The team flew a Macchi MB-326 aircraft, which was replaced by the Pilatus PC-9/A (the Air Force's new pilot trainer) in 1989. Since then, the Roulettes have become a six-plane, seven-member team, which carries out two demonstration seasons each year (one season lasts six months). The Pilatus PC-9/A retired from Roulettes operations in March 2019 and was replaced by the Pilatus PC-21, one of the world's most advanced trainer aircraft.
