Fabian Coulthard claimed his maiden V8 Supercars victory in the opening race of the non-championship event supporting the Australian Grand Prix.
The 30-year-old Holden driver converted his first pole position into the lead at the start of the 12-lap race.
But his hopes of winning took a big hit when he lost the lead during the flurry of safety car pitstops triggered by Alex Premat crashing at Turn 1 on the second lap after hitting Lee Holdsworth's Erebus Mercedes as both were exiting the pits.
At the lap five restart, Tekno Autosports Holden driver Shane van Gisbergen led, chased by Brad Jones Racing's Jason Bright, who had qualified second but started fourth after a penalty for completing a lap after the chequered flag in Thursday practice, and Triple 8's Craig Lowndes.
Coulthard took the restart fourth, but it did not take him long to dispatch Lowndes, passing him up the inside into Turn 3 moments after the green flag flew.
Two laps later Coulthard passed team-mate Bright into Turn 3 to take second and immediately set about carving into van Gisbergen's lead.
He quickly caught van Gisbergen, who held firm until the penultimate lap when his compatriot finally managed to prise open the door into Turn 3, passing him on the inside.
Bright attempted to follow Coulthard through, but was unable to, only to be gifted second place when van Gisbergen's Holden retired later that lap with gearbox issues.
Will Davison had a relatively quiet run to third, but behind him Jamie Whincup prevailed in a fraught late-race battle with team-mate Lowndes to take fourth, with the pair at one stage making contact on the run out of Turn 10.
Lowndes held on to fifth by the slenderest of margins, with both Scott McLaughlin and Mark Winterbottom pulling alongside him as he took the chequered flag.
Further back, Nissan got two cars in the top 10, as James Moffat and Rick Kelly took eighth and 10th.
Coulthard's victory gives him an early lead in the quadruple-header event, with the overall event winner decided based on points awarded in each race.
