Competing in the opening session of the Games, Stubblety-Cook qualified fifth fastest overall for the men’s 100m breaststroke final after clocking 1:00.21 in the semi-finals. He returned for the final and finished fifth in 1:00.20, just one hundredth of a second quicker than his semi-final swim.

Long before Olympic medals and world titles, Stubblety-Cook began swimming with the Water Ratz at Wellers Hill State School in Tarragindi. He later progressed through the ranks to become one of Australia’s leading breaststroke swimmers and now trains with Melbourne’s Nunawading Swimming Club.

The Glasgow campaign marks another milestone in the 27-year-old’s return to international competition. Stubblety-Cook won Olympic gold in the 200m breaststroke at the Tokyo Olympics, added Commonwealth Games gold in Birmingham in 2022, and claimed silver in the event at the Paris 2024 Olympics.

Congratulates Teammate’s Comeback

Fellow Australian Sam Williamson claimed the gold medal in 59.17, producing a blistering final 50 metres to complete a remarkable comeback after recovering from a knee injury that at one stage left him learning to walk again.

After the final, Stubblety-Cook reflected on his performance in an Instagram post.

“Left wanting more, executing the best race plan I could. Stoked to be back racing internationally again,” he wrote.

He also praised Williamson’s achievement, writing: “Super proud of @sam_likesjam for accomplishing all he has over the last 12 months and it’s only the beginning.”

Williamson’s victory was one of the standout stories of the swimming program after the breaststroker fought back from a serious knee injury that forced him to learn to walk again before returning to elite competition.

Strong Showing for the Dolphins

Australia’s Dolphins continued their impressive campaign in Glasgow with another dominant night in the pool, collecting five gold medals and a Games record.

Williamson’s breaststroke triumph was among the highlights as Australia continued to build momentum in the swimming competition, with Stubblety-Cook’s return to an international final providing another positive sign ahead of the remainder of the season.

His latest selection adds another chapter to a career that has already delivered Olympic, world and Commonwealth titles in the 200m breaststroke.

For the Wellers Hill Water Ratz community in Tarragindi, where Stubblety-Cook first learned to swim, his continued presence on the Australian team is a reminder that international success can grow from local beginnings.

A Career Almost Cut Short

Long before becoming one of Australia’s most decorated breaststrokers, Stubblety-Cook faced a significant obstacle that cast doubt over whether he would continue in the sport.

In 2015, after being selected for the Junior Olympic Cup in Tokyo, doctors discovered a golf ball-sized tumour in his left shoulder. The diagnosis required surgery followed by about six months of rehabilitation, interrupting his development at a critical stage of his career.

The uncertainty surrounding his recovery left Stubblety-Cook unsure whether he would swim competitively again. After completing his rehabilitation, he returned to competition and earned selection for the 2017 World Junior Championships.

His comeback gathered momentum over the following years. He made his Commonwealth Games debut on the Gold Coast in 2018 before also representing Australia at the Pan Pacific Championships and the 2019 World Championships. His progress continued over the following years, culminating in Olympic, world and Commonwealth titles in the 200m breaststroke.

At the Birmingham 2022 Commonwealth Games, Stubblety-Cook won gold in the 200m breaststroke and added a silver medal in the medley relay, further cementing his place among Australia’s elite swimmers.

Dolphins Set for Glasgow

Commonwealth Games Australia has named 42 swimmers alongside the nation’s Para swimmers to form the Dolphins squad for Glasgow.

The Australian team includes some of the country’s biggest names, including Kaylee McKeown, Kyle Chalmers, Cameron McEvoy, Mollie O’Callaghan, Sam Short, Lani Pallister, Tim Hodge and Lakeisha Patterson. The squad also features a strong group of debutants, reflecting the balance of experienced performers and emerging athletes selected for the Games.

Among the selections is Sam Williamson, who returns after recovering from a ruptured patella tendon that required surgery, while 14-year-old Para swimmer Mia Hogan will become the youngest member of Australia’s Glasgow swimming team.
