Supercars has undergone a major shake-up - including the reduction of car downforces - which is expected to improve the racing battles and added an element of the unknown for 2023.

He started sixth on the grid but went on to continue Red Bull’s amazing dominance of the series and record his 76th career victory. It is the third year in a row van Gisbergen has claimed the opening race.
