Jack Szewczuk has been racing since he was eight years old. What started on a kart track in South Australia in 2017 has developed into a professional motorsport career that, at seventeen, has already reached the Supercars support grid.
JOURNEY
JACK'S
The karting years was where the foundation was laid. Competing across South Australia, Queensland and Victoria, Jack quickly established himself as one of the most competitive junior kart racers in the country. By 2019 he was already winning club championships and collecting the Kevin Jenner Award for best and fairest. In 2021 he broke a twelve-year lap record at Mallala in South Australia and was named Rookie of the Year in Junior Super Karts.
The 2023 and 2024 seasons confirmed what the earlier years had suggested.
​In 2023, Jack raced under the guidance of David Sera — an 18-time Australian karting champion and Hall of Fame inductee — finishing the season with two national podiums, including a round win.
In 2024, Jack joined the newly formed
JND Racing, the team established by Supercars driver Nick Percat, and wasted no time making his mark. At the opening round of the Australian Kart Championship in Adelaide, Jack delivered JND Racing its first ever AKC round victory — a significant milestone for a team in only its debut season.
He later moved to Empire Kartsport, going on to claim both the Queensland and Victorian State Championships. In Victoria he was untouchable — pole position and victory in every race.
Five national podiums across the two seasons and an overall runner-up finish in the 2024 national championship completed a karting career that made the case for moving to cars impossible to ignore.​​
"No rookie had
ever qualified first
in their maiden
car race series."
Having never completed a race start in a car, Jack arrived at Phillip Island in early 2025 with no circuit racing experience whatsoever — and qualified on pole position.
That debut in the Toyota TGR Scholarship Series was historic: no rookie had ever qualified first in their maiden car race in the series.
The performance spoke directly to Toyota, who selected Jack to step up and compete in the 2025 GR Cup main series — the official support category to the Supercars Championship. He backed that up with a Q3 result at Round 2 of the Scholarship Series at Sydney Motorsport Park, continuing to develop his racecraft across the year.
2026
Jack competes under the Jack Szewczuk Racing banner in the Toyota GR Cup Series, carrying car #39 with the valued support of P&K Race Prep, Action Motorsport, Borger Cranes, Parramatta Toyota, and a growing network of commercial partners.
2026 has been a strong start. Round 1 at Sydney Motorsport Park opened the season with a P2 qualifying result — 0.0033 seconds off pole — and front-running pace across the weekend. Jack currently sits fourth in the championship standings.
