Jamie Whincup racing the repaired Craig Lowndes car from the Clipsal 500 was a disappointing 22nd, starting alongside fellow points front runner Lee Holdsworth.
James Courtney was fighting amongst that group but fading rear tyres led Courtney to attempt defensive moves that raised the ire of race control, leading to first the bad sportsmanship flag, then a black flag drive through penalty which dropped him down field.
A slow start from Mark Skaife off the front row saw a collision with Steven Richards at turn 3 of the first lap.
Skaife broadsided the wall but Richards attempted to continue with a punctured left rear tyre, limping back to the pits.
Lee Holdsworth was pinged for a drive-through for an unsafe pitstop release, emerging onto the track as rain began to fall and made contact with Paul Dumbrell.
[1] Whincup stayed out during the brief rain squall, and took advantage of being able to pitstop at a better time, jumping back into the field in third place, right in front of teammate Craig Lowndes, the Team Vodafone pair race to the finish together.
