The first 44-lap sprint of the Beaurepaires Tasmania SuperSprint uncovered a number of key storylines.
Notably, Shane van Gisbergen claimed another win to extend his winning streak in 2021 to six.
Just two other drivers have won six races to start a season: Allan Moffat in 1977, and Mark Skaife in 1994.

It was van Gisbergen’s 46th career win, bringing him within striking distance of Peter Brock’s marker of 48 wins.
Only four other drivers have won more races; Jamie Whincup (122), Craig Lowndes (110), Mark Skaife (90), and Scott McLaughlin and Garth Tander (both on 56).
Whincup completed a Red Bull Ampol Racing one-two, with the seven-time champion scoring his 225th career podium.
Anton De Pasquale scored a maiden podium for the Shell V-Power Racing Team. It was his sixth career podium.
Mark Winterbottom, who finished seventh, extended his run of finishes at Symmons Plains to 41.
The day also featured a career-best qualifying result for Matt Stone Racing’s Jake Kostecki, who benefited from a grid penalty for Brad Jones Racing’s Jack Smith to line up 11th.

BJR driver Todd Hazelwood impressed in his 100th career race, rising 10 spots from 24th to finish 14th. Unsurprisingly, he was the biggest mover in the field.
Penrite Racing’s David Reynolds was the biggest loser, dropping six spots from 10th to 16th.
