David Reynolds was "gutted” to miss out on overall Albert Park honours after retiring from the finale.
Reynolds entered Sunday within striking distance of Shane van Gisbergen.
Van Gisbergen crossed the line 20th in Race 9 following a late tyre failure, but still clinched the Larry Perkins Perpetual Trophy.
Reynolds was effective fifth when he found the Turn 8 wall while chasing Cam Waters.
Grove Racing was forced to sideline the #26 Penrite Racing Mustang, ending Reynolds’ weekend early.
Had Reynolds remained on track, he would have won the Perkins Trophy by 17 points.
Instead, he was consigned to a DNF, which was a far cry from his four podiums in five previous starts.
"It’s not the result we wanted to end a really strong weekend,” he said.
Reynolds scored three podiums
"I was following Cam Waters into Turn 8 and something odd happened in the front left of the car and it sent me into the fence.
"If I finished where I was we would have taken home the most points for the weekend as a team.
“I’m gutted for our team. That’s just how it goes sometimes.”
Teammate Lee Holdsworth, who finished 10th on Sunday and 11th overall, reiterated the positives despite Reynolds’ DNF.
The Braeside squad podiumed in three races, included a double-podium on Saturday.
That result marked the first double-podium for the team since Tailem Bend 2018.
“There’s no doubt it’s been a great event for our team still, four trophies and a pole position,” Holdsworth said.
"It’s a bit unfortunate what happened to Dave, I think it would have cap it all off with the most points as a team.
“We’ll focus on taking our speed into Perth."
