Chaz Mostert broke through for his first Supercars win at the Australian Grand Prix on Sunday but Fabian Coulthard took overall honours for the round.
DJR Team Penske's Fabian Coulthard has taken overall honours at the non-championship Supercars round at the Australian Grand Prix, despite a blown tire in race four on Sunday.
Coulthard was leading seven laps in to the 13-lap final race when he sustained a puncture to his left front tyre, forcing him into the pits in his Ford Falcon.
The New Zealander's misfortune allowed Prodrive Racing's Chaz Mostert to break through for his first win at the Albert Park circuit in his Ford.
Red Bull Racing's Shane van Gisbergen was second in his Holden Commodore and Freightliner Racing's Tim Slade guided his Commodore to third.
Coulthard finished race four in 20th but wins in race two and three and a second place behind teammate Scott McLaughlin in race one were enough to give him the overall win.
McLaughlin finished the final race in 17th after he was involved in a multi-car collision at turn one on the opening lap, but had earned enough points to finish the round second overall.
In a dramatic turn of events, Red Bull's Jamie Whincup briefly took the lead when Coulthard pitted.
Whincup, who started from pole position on Sunday, was in the box seat to secure the round win until he too suffered a blown tyre and pitted in his Commodore.
Mostert was third overall at Albert Park, with Nissan Motorsport's Michael Caruso and Whincup rounding out the top five.
The Supercars championship resumes at Symmons Plains in Tasmania on April 7.
