Clydesdale was a consistent member of the Australian's women's junior teams. She represented Australia at the inaugural FIBA Under-17 World Championship for Women in Toulouse, France where Australia placed seventh. She was then named to the Gems squad and helped them take home the Gold at the Oceania Under-18 Championship and qualify for the World Championship the following year in Chile. Clydesdale was once again named to this squad, where they were narrowly defeated in the Bronze medal match by Brazil, finishing the tournament placed fourth.
