Courtney recovered from a poor second race to pull through the field in the final race of the weekend and take back third for the event.
"We went a little bit the wrong way with set-up so we had to fight pretty hard to get back up. We engineered it backwards and went back to sixth so we went the other way," Courtney said.
Winterbottom got Courtney from the start in R2 and that wasn't the end of the problems for yesterday's winner. He first succumbed to Toll Holden Racing Team's Garth Tander on lap one and on the very next lap Ingall and Jim Beam's Will Davison.
Within three laps Courtney was in fifth. It appeared there were some losses with his car with the changes they had made overnight compared with the other front-runners.
Further down the order Tander took fourth spot overall - having finished in P4 in all three races.
Will Davison was fifth for Jim Beam Racing, after another consistent weekend in his Ford Falcon: "Obviously a podium would have been nice at our home track, but I have again scored a good amount of points and we continue to learn more about the new control tyre," said Davison.
"We set out to make sure we qualified well and to finish top five for the weekend is a very solid performance and a credit to the team as we still have some issues with improving tyre life."
Jamie Whincup was next up climbing six spots in race 2 to finish third. Although he couldn't repeat that in the final race after an error early on, he still scored good points bringing his Team Vodafone machine home in P6.
"After our positive result this morning I was really looking forward to Race 3," Whincup explained. "The car showed real promise in overtaking and I thought I would be able to challenge the leading cars. I made a silly mistake on lap 4 though which slid me back to seventh.
"Then after my pit-stop I never really had the opportunity to challenge anybody properly. We have still gained 210 points however, which keeps me within striking distance of the Mark (Winterbottom) and Garth (Tander)."
