Quick Contact


Mark Tonelli is a legendary Australian swimmer, Olympic Gold Medallist, and one of the country’s most accomplished and versatile all-rounders in the pool. Diagnosed as asthmatic in his youth, Mark was encouraged to take up swimming for its health benefits. Little did anyone know that this would be the beginning of a remarkable journey that would see him become a key figure in Australian swimming history.

Throughout his distinguished career, Mark won an unprecedented 10 Australian Championships across three strokes – freestyle, butterfly, and backstroke. He represented Australia internationally from 1973 to 1980, making his debut at just 16 years old at the Belgrade World Championships, where he placed 6th in the 200m Backstroke while breaking the Commonwealth record.

Mark made history as the first Australian to break the magical minute barrier in the 100m Backstroke and became one of the sport’s most decorated athletes. He won his first major international gold medal as a schoolboy at the Christchurch Commonwealth Games, clinching gold in the 100m Backstroke and silver in both the 200m Backstroke and Medley Relay. At the Cali World Championships, Mark narrowly missed out on gold, earning silver in the 200m Backstroke by just 0.2 seconds.

He also competed at two Olympic Games, with his most famous achievement coming in 1980, when he was part of the Australian 4×100 Medley Relay team that won Gold at the Moscow Olympics—a moment forever etched in Australian sporting history thanks to the iconic commentary: “Gold! Gold! Gold!”

Mark’s success was not just limited to the pool. He pursued a scholarship at the University of Alabama, where he graduated cum laude, majoring in Communications. He earned numerous NCAA medals, was honoured as a four-year double All-American, and became only the second Australian, after the legendary Murray Rose, to win a US Open Championship.

Appointed as Captain of the Australian Swimming Team in 1978, Mark was later honoured as Captain of the Australian Team of the Year by Sport Australia after his second Olympics. His leadership, determination, and commitment to excellence continue to inspire athletes and leaders worldwide.
