"I would much prefer it to be in December but it is May so we have a little way to go."
The Shell V-Power Fords dominated their rivals a fortnight ago at Barbagallo Raceway, where the team had struggled 12 months earlier.
This week, they head to the rural Victorian track of Winton, where they actually enjoyed some success a year ago.
"We qualified on the front row there last year and finished on the podium - that was with our car last year and I think we go there with a much better package this year so hopefully we will be in contention and we can be on that podium and spray some more champagne," Coulthard said.
• Defending Supercars series champion Shane van Gisbergen might have been overshadowed recently by his fellow Kiwis Coulthard and Scott McLaughlin, but he's thrilled about his country's dominance of the Australian championship.
Coulthard leads van Gisbergen by 19 points after four rounds while McLaughlin dominated the last round at Barbagallo and has stormed into title contention.
While van Gisbergen and his Red Bull Holden Racing Team search for ways to catch-up to their Ford rivals, the 27-year-old admits he is stoked that the Kiwi contingent are leading the way this year.
"We are obviously in different teams," van Gisbergen told the Herald. "We have qualified top three in a couple of races but not been able to do it in a race just yet.
"That would be the most amazing thing - I don't care what the order is - to have all three Kiwis on the podium would be awesome."
It appears the trio could well fight out the 2017 title if current form continues.
"We are all in the best cars and teams of our careers so we will all be pushing hard," he said.
