David Reynolds has scored a shock pole for Race 6, with points leader Shane van Gisbergen stung by a red flag.
An accident for Jake Kostecki called an early end to Thursday’s first ARMOR ALL Qualifying session.
It helped Reynolds, who set a banker lap, secure his 14th career pole and first since Townsville 2019.
Reynolds’ 1:45.678s proved just 0.02s quicker than Practice 1 fast man Anton De Pasquale.
The Grove Racing veteran became the sixth different pole-sitter in as many sessions in 2022.
"I was a little bit lost after practice," Reynolds said.
"We made some good changes and I did a 98 per cent lap, and it was good enough for pole.
"I'm really stoked with that, it's a full credit to the team at Penrite Racing.
"We've worked so hard the last couple of months and produced some good cars."
Van Gisbergen was unable to set a lap
It was a different story for van Gisbergen, who lost his first flying lap due to a kerb strike.
Van Gisbergen, who topped Practice 2, triggered a kerb strike at Turn 10 and had his lap time voided.
Van Gisbergen returned to pit lane just as Kostecki found the barriers at Turn 5.
The Kostecki incident triggered a red flag, and the session didn't restart.
Van Gisbergen, who leads the championship by 67 points over De Pasquale, was the only driver unable to set a lap time.
The points leader was recorded 25th and last, which will become 24th for the race due to Kostecki's fastest lap being scratched.
Reynolds will share the front row with De Pasquale, with Chaz Mostert qualifying third.
'I'm really stoked with that'
Mostert fired off at Turn 1 after he set his lap time, but managed to return to the track.
Will Davison qualified fourth, with Lee Holdsworth making it a Penrite Racing one-five result.
Nick Percat, Cam Waters, Macauley Jones and Thomas Randle filled positions six through nine.
James Courtney, who was second in Practice 2, will start his 500th race from 10th.
Broc Feeney, whose car was repaired after a Practice 1 crash, will start 17th.
The 20-lap Race 6 will launch at 2:20pm AEST on Friday.
