Who is Mark Tonelli?

Mark Lyndon Tonelli is a former Australian backstroke, butterfly and freestyle swimmer of the 1970s and 1980s, who won a gold in the 4 × 100 m medley relay at the 1980 Moscow Olympics as a makeshift butterfly swimmer in the self-named Quietly Confident Quartet. Tonelli unofficially led the relay team and was an athletes' spokesperson who fought for the right of Australian Olympians to compete in the face of a government call for a boycott to protest against the Soviet invasion of Afghanistan.

Tonelli took up swimming due to his asthma, and quickly came to prominence. Selected to represent Australia at the 1973 World Championships, he came sixth in the 200 m backstroke at the age of 16. He won his first Australian titles in 1974 in the 100 m backstroke and 200 m butterfly and went on to the 1974 Commonwealth Games in Christchurch where he won his first major international race, the 100 m backstroke, and took silver in the 200 m backstroke. In 1975, Tonelli won his only individual medal at global level, a silver in the 200 m backstroke at the World Championships in Cali, Colombia.
