Selected for the Junior Olympic Cup in Tokyo at just age 14, Zac knew he was determined to continue his Australian Swim Team journey. But in 2015, Zac’s life and career took a devastating turn with the diagnosis of a golf-ball sized tumour in his left shoulder. The uncertainty of whether he would swim again combined with a 6-month recovery solidified Zac’s fighting attitude and true grit to face adversity head on.

Zac Stubblety-Cook made the transition to train under his current coach Vince Raleigh while he completed his final year at school in 2017. This change elevated Zac’s swimming career, where he narrowly missed making his first senior team, only to make the World Junior Championships where he finished 3rd in the 200m Breaststroke.

2018 saw Zac make his debut on the Australian Dolphins senior team for the Commonwealth Games, finishing 11th in the 200m Breaststroke. Later that year, Zac made the Pan Pacific Championships team, where he closely finished 2nd. This race also saw him swim the fastest 200m breaststroke in a textile suit by an Australian up until 2019.

Alongside Zac’s swimming achievements, he is also studying a double degree in Psychological Science and Business at Griffith University. 

In 2019, Zac Stubblety-Cook competed at his first World Championships placing 4th overall in a personal best time in the men’s 200m breaststroke which he improved on at the Olympic Trials by breaking the Australian record. Turning his focus to winning Gold at the Olympic Games in Tokyo, Zac’s devotion to his training working alongside his coach Vince Raleigh all came to fruition as he stood on the top of the podium with pride. He added a Bronze to his Gold in the Mixed Relay.

Zac smashed the WR in the 200m breaststroke in a stunning 2:05.95 (1:01.89) on night two of the 2022 Australian Championships in Adelaide.The 23-year-old from Brisbane was 0.17 under the previous mark of 2:06.12 set by Russian Anton Chupkov at the 2019 World Championships. He is now the first man to go under 2:06.00.
