Jon graduated in 1983.
He became a national name in his infamous David versus Goliath 200m butterfly swim at the 1984 Los Angeles Olympics. Beating all odds, he took out the gold medal—beating the race favourite, Michael Gross of Germany.
He was the Australian 50m, 100m and 200m butterfly champion and was awarded the Medal of the Order of Australia (OAM) for his services to swimming.
Today, Jon lives in Townsville and manages a number of aquatic facilities and is involved with the design and construction of commercial aquatic facilities.
