With just two rounds remaining, Van Gisbergen is third in the points and reeling in Ford rival Mark Winterbottom.
The TEKNO Autosports driver said a consistent weekend at Phillip Island will set him up for a career best series finish.
“I know we’re going to be fast at Homebush, so this will be the more important weekend for points,” Van Gisbergen said.
“We’re in a good championship position but I’m not paying too much attention to where others are. I’m just concentrating on each race.”
The VIP Petfoods/Lucas Oil Commodore has been one of the fastest cars of the past few rounds, with Van Gisbergen and Jonathon Webb picking up a win at the Gold Coast three weeks ago, and third overall in the Pirtek Endurance Cup.
The Phillip Island 400 sees the series revert to the Super Sprint format with two 23-lap 100km dashes on Saturday and a 45-lap, 200km thriller.
“We’re carrying a lot of momentum into the event and I’m confident TEKNO Autosports are on top of what we need for a quick car at the Island this year. We were alright last year but could have been better,” he said.
“I’m just going to go out there and give it everything and see where we end up!”
