"Our cars were really good last weekend, but they can always be better. There's always something to learn. We still had over and understeer and other things and want to make the car better. There will be a few things we'll try this weekend to improve it," said van Gisbergen.
"We've had a good set-up for both qualifying and the race, which helps a lot. We didn't need to tweak much between the race and qualifying, which is cool and our tyre life was good and that really helps in longer races.
"Our cars have been good here for a couple of years now, and I think it's because how well they ride the bumps and look after the tyres."
Van Gisbergen's Red Bull Ampol Racing are the team to beat at the moment with the likes of DJR's Shell V-Power Racing pairing of Anton Der Pasquale and Will Davison, Walkinshaw Andretti United's Mostert and Tickford Racing's Cameron Waters struggling to keep up.
It doesn't look good for the rest of the field with everyone being back on the same circuit and using the same tyres. Sure, there are three 39-lap races this weekend (as opposed to 88-lap races last weekend), but van Gisbergen and Whincup combined to win four of the six races across last year's Townsville double-header.
"On this type of track we always seem to go alright. Last weekend it was a little bit surprising how fast we were, but I'm sure this weekend it'll be closer," said van Gisbergen.
There is one race today and two tomorrow.
