Stewart Thomson began kayaking at school when he became involved in the Murray River Marathon. His school days’ success encouraged him to continue with the sport and he has built on that success in recent years. Australian canoeing is strong and competitive and Stewart has continued to excel in his chosen sport.
In 2004 he was selected to represent Australia in the Junior Men K1 Marathon team in Portugal, and followed this with selection for the World Cup Championships in France in the K1 event, and the K2 event in Norway. In 2005 he again represented Australia in the World Championships in Perth in the K2 event.
