Chaz Mostert enters into his sixth season with Walkinshaw Andretti United in 2025, coming off the back of an impressive 2024 Supercars season, finishing fourth in the Drivers Championship.

32-year-old Mostert, who hails from Browns Plains in Queensland, pilots the No. 25 WAU Supercar.

Since his Supercars debut in 2013, Mostert has 348 Supercars race starts to his name, which have included 24 wins, 98 podium finishes, and 26 pole positions.

His impressive résumé also includes being a two-time Bathurst 1000 winner (2014 and 2021) and a 2017 Enduro Cup winner.

In his first full season of Supercars with Tickford Racing, Chaz raised the Peter Brock Trophy at the Bathurst 1000, crossing the line first after starting from last with co-driver Paul Morris.

2015 was a year of highs and a low. After winning five races and claiming 14-podium finishes, as well as winning the Pole Position Award for the year, a horror accident at Bathurst where he broke his wrist and femur meant Chaz was unable to complete the season.

In 2024 Chaz was recognised for his authentic character both on and off the track, clean sweeping the Supercars Gala Awards night winning the Drivers Driver award, The Barry Sheene Medal for the second year in a row and the inaugural winner of the Jim Richards Award.

Chaz has become one of the consistent stars of the Supercars Championship, and heads into 2025 ready to take on what looks set to be a huge year.

He will drive alongside Ryan Wood in the two-car Walkinshaw Andretti United operation.
