In Sydney, Ridley finished second in the triple jump, making 10.86m, eighth in the 90m hurdles and 10th in the long jump, while D’Sylva came third in the 2km steeplechase event with a personal best time.
Ferguson was 10th in the 800m, just missing out on the final, and Tolcon finished second in the 200m and 4x400m events and third in the 4x100m.
While the girls attend Mercedes College, St Mary’s Anglican School for Girls and Methodist Ladies’ College, they became friends through athletics.
Ridley only joined the McGillivray Oval-based club a year ago, while Ferguson has been competing under UWA for five years.
Tolcon said it was great travelling together to Sydney and she enjoyed watching all the events at the Junior Championships.
The girls will travel to Singapore for a little athletics international meet in July.
At the State Championships, UWA’s under-11B team of Daniel Walsh, Jackson Hamilton and Will Wiggett won a clean sweep ” gold, silver and bronze ” in discus, with Hamilton also breaking two Australian Athlete with a Disability records.
