Day two of the SuperSprint at Symmons offered even more bumper-to-bumper action than Saturday, with team Red Bull Ampol asserting itself despite a late afternoon hiccup.
Monster Energy's Cameron Waters once again got off to a hot start in the qualifiers, finishing pole for both races seven and eight. Much like race six on Saturday, Waters edged out Jamie Whincup in second to an early lead in race seven.
The first turn at the hairpin saw plenty of contact, including Shell's Anton de Pasquale, who got into a spin and caused plenty of congestion for the middle of the pack.
The second turn on lap two saw even more chaos, as contact sent Boost Mobile's James Courtney into roadside signage before he bumped into SCT Motor Sports' Jack Smith, taking them both into the beach.
Waters, Whincup, Erebus' William Brown and van Gisbergen managed to avoid the mess in the middle, with van Gisbergen making chase.
Whincup and Waters had themselves a drag race on the straight in the 25th lap, with the former able to cut in after edging out Waters at turn six.
Shell's Will Davison did as he could to challenge Whincup, but his stability at the hairpin allowed Whincup to out-manoeuvre Davison.
Whincup then did the same to Waters one lap later. Van Gisbergen, with a fresh set of tyres, moved up to join his teammate in second.
Team Red Bull Ampol chose team-work over history, with van Gisbergen keeping a distance from Whincup who would win the race.
Both cars ended up six seconds clear of Davison, who finished third.
The weekend wind fittingly died down as race eight got underway.
Waters and Mobil's Chaz Mostert held the top positions, with van Gisbergen and Whincup having their work cut out for them at spots seven and six respectively. Mostert gunned it from the start to an early lead.
Waters managed to give chase, with Yellow Cover's Zane Goddard (in fifth) holding his own with Team Red Bull Ampol right behind him, and Team Shell in front. Mostert held his sizeable lead the entire race, with Waters holding solid real estate in second
Whincup and van Gisbergen did what they could to make ground on their starting positions, but Davison held them at bay as teammate De Pasquale held third place.
The action heated up in the final three laps for second place, as De Pasquale tested Waters and pushed through him before turn six.
Then it was Davison's turn to edge into the podium, out-racing Waters in the straight on the second-last lap. With about an 11 second lead, Mostert never fretted, taking out his first race win since 2019.
