Charlotte, 23, follows a demanding training schedule with Special Olympics Canterbury at Rolleston and is also a squad swimmer with the Selwyn swim club.
That hard work paid off in Brisbane when Charlotte won gold in the 25m breaststroke, as well as three silvers in the 25m freestyle, 25m backstroke and 100m individual medley.
Because Charlotte is a New Zealand citizen, rules dictated she could not be awarded the title of Australian champion in her winning breaststroke race. A second-placed Australian swimmer shared the top spot and also received a gold medal.
