Kiwi Shane van Gisbergen claimed Sunday's Supercars race win in Townsville to reduce compatriot Scott McLaughlin's championship lead to 131 points.
The 2016 champ made a strong start from pole position and held off his Red Bull Holden Racing teammate Jamie Whincup to take the chequered flag for his team's second straight one-two finish but a reverse of Saturday's order.
McLaughlin started the race from seventh and fell as low as 11th by the end of the opening lap but his Shell V-Power Racing team brought him in earlier than his rivals for his first stop. The under-cut helped and he came back up the order once the latter stoppers completed their refuel, eventually finishing third for the second day running.
Whincup also opted for the early first stop and he took over the lead in the middle stint of the race but Van Gisbergen's tyres lasted better and he came roaring back to pass the reigning series champion shortly before the final stop.
A late safety car bunched the field up and gave Whincup a four-lap dash to try and put a move on his teammate but Van Gisbergen held him off for his 27th career win.
