Originally from South Africa, Hewat spent his formative years there before relocating to Queensland, Australia. His mother is Australian, and his father is of English origin from South Africa.[1]
In 2016, he joined the Queensland Reds, competing in Super Rugby.[2] Under coach Nick Stiles, he made his debut for the Reds, aiming to bring fresh energy to the team after a series of disappointing performances.
He played sparingly due to two major injuries, undergoing a double shoulder operation that kept him off the field for 9 months. Upon his return, during his first training session, he suffered a knee ligament injury, sidelining him for another 9 months. These setbacks led to him falling out of favor with the Queensland Reds coach.
As he was set to join England, his agent informed him of an opportunity to become a JIFF (player developed through the French system) in France.[1]
His French journey began with Stade Aurillacois in the 2018-2019 season. While he initially played with the U20 team, he quickly transitioned to the professional squad. Despite a slow start, he became a key player for Stade Aurillacois in subsequent seasons. In the summer of 2021, he made another significant move, signing with Section Paloise in the Top 14.[4]
Hewat's adaptation to the French rugby style took time, but by the 2022-2023 season, he had become a prominent figure in the forward pack for Section Paloise. His contributions led to a contract extension until June 2026.[5] Notably, in January 2023, his defensive prowess was highlighted with a tackle success rate of 96%, the highest in the Top 14.[6]
