VanGisbergen on top at Barbagallo
Shane VanGisbergen has claimed his 62nd career victory holding off James Courtney at Barbagallo Raceway.
Courtney was denied his first victory in six years as VanGisbergen surpassed him with six laps to go.
Will Davison finished third after he found a rhythm winning Sunday's earlier race.
"What an awesome weekend, thanks to the team so much, the car's been brilliant." VanGisbergen said.
"That race was pretty funny, I didn't realise James was the leader, I thought it was Will and I.
"I took off after James, so sorry for stealing that one from him."
Van Gisbergen extended his championship lead to 164 points over Anton De Pasquale.
The teams' championship margin between Red Bull Ampol Racing and the Shell V-Power Racing Team is 13 points.
Action will resume at Winton Motor Raceway later this month.
