Conditions on-track were wet to begin with, and slowly dried until a further sprinkle in the closing minutes.

Jacobson's team-mate Josh Kean was also on the pace, finishing just 0.0629 seconds adrift in the difficult conditions.
Paul Morris Motorsport's De Pasquale was third, after topping the timesheets for a significant part of the session.
Bryce Fullwood and Richard Muscat claimed fourth and fifth in the closing minutes, ahead of Dumbrell and championship leader Todd Hazelwood.
Super2 rookies Brodie Kostecki and Will Brown were eighth and ninth, while Shae Davies rounded out the top 10.
