The 2023 TCR Australia Series (known for sponsorship reasons as the 2023 Supercheap Auto TCR Australia Series) was the fourth season of the TCR Australia Touring Car Series. The series ran as part of SpeedSeries and featured two rounds as part of TCR World Tour.
The series was won by Josh Buchan in a Hyundai Elantra N TCR.
The following teams and drivers are under contract to compete in the 2023 championship. Kumho is the new official tire supplier.
The points system for 2023 was restructured. Races 1 and 3 award maximum points, while race 2, which features a starting grid based on reversed results from race 1, is worth slightly reduced points. Additionally, the top five drivers in qualifying now receive points instead of only the pole winner, and the driver who sets the fastest lap in a race receives points.
