Two talented swimmers from South Brisbane have earned selection to represent Australia at the 2026 Commonwealth Games in Glasgow. Mollie O’Callaghan and Zac Stubblety-Cook will join the Dolphins squad as the nation prepares for competition at the Tollcross International Swimming Centre. Their inclusion highlights the continued strength of swimming talent emerging from the Brisbane region.
Mollie O’Callaghan began swimming at age four and started competing at seven. Training under coach Dean Boxall at St Peters Western Swim Club, she made her Commonwealth Games debut in Birmingham at age 18. She returned with five gold medals and two silver medals, establishing herself as a major force in Australian swimming.
O’Callaghan achieved historic success at the 2023 World Aquatics Championships in Fukuoka. She became the first woman to win both the 100m and 200m freestyle at a single championship while setting a new world record in the 200m freestyle with a time of 1:52.85. Her Olympic performance in Paris 2024 further cemented her status with gold in the 200m freestyle and an Olympic record of 1:53.27.
At 22 years old, O’Callaghan arrives in Glasgow as one of the most credentialled swimmers in the Australian squad. She holds the world record for the short course 200m freestyle and has equalled Ian Thorpe’s record of 11 World Championship gold medals for an Australian swimmer. Her journey reflects dedication and consistent excellence in the sport.
Zac Stubblety-Cook’s path to elite swimming began with learning water safety at Wellers Hill Water Ratz in Tarragindi. Born in South Brisbane on January 4, 1999, he initially feared the deep end but developed into a formidable breaststroke specialist.

After six months of rehabilitation, Stubblety-Cook returned to training with renewed determination. He earned selection for the 2017 World Junior Championships and the 2018 Commonwealth Games. His breakthrough period from 2021 to 2022 saw him become Olympic champion, World Champion, Commonwealth Games champion, and world record holder in the 200m breaststroke with a time of 2:05.95.
Stubblety-Cook will defend his Commonwealth title in the 200m breaststroke in Glasgow.
