Dean Hewitt

Hewitt first played mixed doubles with his mother, Lynn Hewitt. Lynn and Dean together played as the Australian national mixed doubles curling team at the 2017 World Mixed Doubles Curling Championship and the 2018 World Mixed Doubles Curling Championship

At the 2019 World Mixed Doubles Championship, Hewitt and his new teammate Tahli Gill made it to the semifinals before being eliminated by Sweden's Anna Hasselborg and Oskar Eriksson. In the bronze medal match, they again lost to John Shuster and Cory Christensen from the United States. Their fourth-place finish was the best finish ever for an Australian team at any World Curling Championship to that point. Gill and Hewitt were qualified for the 2020 World Mixed Doubles Championship, but the event was cancelled due to the COVID-19 pandemic.

At the 2021 Olympic Curling Qualification Event in December 2021, Gill and Hewitt made history when they won qualification to the mixed doubles tournament at the 2022 Winter Olympics. They are the first ever Australian curling team (in any curling discipline) to qualify for the Winter Olympics. At the Olympics, they finished with a 2-7 record, finishing in 10th place.

Gill and Hewitt would continue to find success in mixed doubles in the next Olympic quadrennial from 2022-26, performing well on the mixed doubles curling tour and consistently being ranked as one of the top 5 teams in the world. They would also notably win a bronze medal at the 2025 World Mixed Doubles Curling Championship. This success would allow them to compete in the 2025 Olympic Qualification Event in the hopes of representing Australia at the 2026 Winter Olympics. Gill and Hewitt would finish round robin play with a 6-1 record, qualifying for the playoffs, but would lose to South Korea's Kim Seon-yeong and Jeong Yeong-seok 10-5 in the final qualification game, failing to reach the Olympics. However, Gill and Hewitt would bounce back at the 2026 World Mixed Doubles Curling Championship, where they would finish 8-1 after the round robin and after beating Italy in the semifinals, would go on to defeat Sweden's Therese Westman and Robin Ahlberg 8-4 in the gold medal game to win their first world championship, as well as the first world championship title in curling ever for Australia.

Dean Hewitt began curling when he was 6 years old. Hewitt is from a curling family, as his mother and former mixed doubles partner, Canadian-born Lynn Hewitt, played curling in Canada from her childhood. When she met Australian farmer Stephen (Steve) Hewitt, she married him and they moved to Australia, and her husband began curling too. Steve was member of the Australian national men's team and played in several Pacific Curling Championships.

Hewitt studied a Bachelor of Exercise and Sport Science and a Master of Clinical Exercise Physiology at Deakin University. Outside of curling, Hewitt is a trained exercise physiologist, and works at an ice rink and a supermarket.
