"Once I let loose and drove normal I was much better for it.
"Scotty is in a different position to me because he is the chaser. I think if you are that close on points - I would rather be the chaser and put a lot of pressure on the other guy.
"In saying that, you are up against a six time champ, who is pretty good under pressure."
The battle between the two leading teams extends to the team's championship too where DJR Team Penske hold a handy lead.
Van Gisbergen said winning that championship is worth more than just pride as you get the first two positions on pit lane next year as reward.
"You get a much better spot in the pit lane, the 28-year-old said. "In racing you can react to the other guy - you can see how much fuel they've put in and when they are exiting the pits and you can react to that. It is a pretty good spot in strategy terms so it would be good to get into that.
"We have to score as many points on my side of the garage and do a good job there.
"It is not going to be easy - the DJR cars are pretty quick and Scotty is a good driver."
Van Gisbergen is expecting the brand new circuit to be a difficult place to pass, which will make qualifying extremely important.
"I had some promotion work there so I went at the same time and did a lot of study of the track.
"It looks a big commitment type of track. It is a little like Townsville where it is fast and flowing but then it is a little like Clipsal with the 90 degree corners and it is like Gold Coast because it is along the coast line of the surf beach."
Predictions
Man to beat: Scott McLaughlin (though Whincup will be right with him)
Dark Horse: James Courtney - with no historic data to call upon and a love of street circuits he could be a contender
Pressure on: Whincup - he holds the championship lead. One mistake and it is a different ball game.
Tip your hat: To veterans Jason Bright and Todd Kelly, who will retire after this weekend. Will Davison could also be out as a fulltime driver next season.
