Chaz Mostert won the final race of the weekend at Sydney Motorsport Park in a three-lap dash to the end of the race.
Anton de Pasquale got a strong start to the race, moving into the lead before the first turn, with pole-sitter Brodie Kostecki falling into second behind him.
Garry Jacobson and Tim Slade were forced to start the race from the pit lane after both cars rolled out to the grid on wet tyres before the track was declared wet.
Shane van Gisbergen made a strong start to the race moving up five positions by the end of the opening lap after starting from 21st on the grid.
The Triple Eight driver would continue to move forward until lap 8 when van Gisbergen was caught out but the changing weather conditions, running off track at the final corner, managing to get back on track, though he would pit for wet tyres.
However, the rain eased and he was forced to pit again to get back on slicks soon after leaving him almost 1.5 laps down at one point.
Teammate Broc Feeney also made a strong start taking advantage of his supersoft tyres to follow Kostecki when he moved into the lead of the race while keeping pressure on the Erebus entry.
The safety car made an appearance on lap 32 after Jake Kostecki and Garry Jacobson were both stopped on track in separate incidents, Jacobson for an oil pressure issue while Kostecki spun at the final turn and was unable to refire the car.
The safety car allowed SVG to catch back up to the field before a second safety car on lap 47 when Nick Percat found himself stuck in a gravel trap after contact with Scott Pye saw the Kiwi get back on the lead lap.
After getting back on the lead lap van Gisbergen began clawing his way back through the field.
As the weather deteriorated Brodie Kostecki was the first of the leaders to stop for wet tyres on lap 66. Leader Chaz Mostert came in for wet tyres a lap later with de Pasquale who no longer had radio communication with his team, pitting at the same time.
Jack Le Brocq attempted to stay out on slick tyres in rapidly declining conditions, with less than 10 laps remaining he found himself stuck in a gravel trap, once again bringing out the safety car.
SVG was in seventh when the race restarted with three laps remaining, moving to sixth by the time he crossed the line.
Brodie Kostecki took a second-place finish, with de Pasquale in third, making contact with the wall after the race, on his way back to pit lane.
Andre Heimgartner found himself inside the top ten for most of the race finishing in fifth, while fellow Kiwi Chris Pither dropped back through the race limping across the line to finish 20th after starting the race in 13th.
Supercars will be back on track for the next round March 26-27 at Tasmania.
