Chaz Mostert has become the first driver to qualify for Supercars’ inaugural Grand Final, following a commanding victory in Race 30 at the Penrite Oil Sandown 500. Starting from the front row, Mostert launched cleanly and immediately established control of the race. Walkinshaw Andretti United teammate Ryan Wood supported the strategy from second position, effectively shielding Mostert from sustained pressure and helping to stabilise the pace through the early stages. From that point, Mostert managed the stints with precision, converting track position and team execution into a decisive win.

The result carried significant championship consequences. Mostert’s win, combined with a measured fourth-place finish for Broc Feeney, has moved the Ford driver to the top of the overall standings for the first time this season. It is also the first time he has led the championship since the 2023 Newcastle round. Although Feeney surrendered the points lead, his position remains strong: he holds a 119-point buffer above the transfer cut line, with 150 points available in the remaining Sandown race, leaving him well placed to secure his own Grand Final berth on Sunday.

The standout recovery, however, belonged to reigning champion Will Brown. After qualifying only 15th, Brown entered Race 30 under genuine elimination threat. Rather than overreaching early, he built his race through steady gains in the opening two stints, keeping contact with the midfield pack. That approach set the platform for a decisive final stint, where a fresh right-rear tyre critical at Sandown given the corner loading allowed him to attack with confidence and consistency. Brown ultimately finished second, a result that lifts him to 56 points above the cut line heading into the final semi-final race.

Behind the front-runners, the qualifying battle tightened sharply. Matt Payne finished sixth and now clings to the last available transfer position, only 47 points clear of the cut. Kai Allen, seventh on the day, is the first driver outside the bracket and will require a strong result in Race 31 to advance.

Tickford Racing endured the most difficult afternoon. Cam Waters slipped from ninth to 12th, while Thomas Randle recovered only to 16th after starting 22nd. With Waters 57 points and Randle 104 points below the cut, Tickford’s pathway has narrowed to a near-must-win scenario on Sunday. Rain remains a potential variable, but the final semi-final race is now a high-stakes contest for the remaining Grand Final positions.
