CoolDrive Racing’s Dean Canto and Penrite Racing’s Will Brown completed the top five; the latter having also spent time at the top of the order.
Moffat ended up sixth from 23Red Racing’s Alex Davison and Brad Jones Racing’s Tim Blanchard, who threatened the top spot late before finding traffic.
Craig Lowndes and Dale Wood completed a top 10 split by 1.4s.
Twenty-four cars took to the track, with Greg Murphy sampling both Shell V-Power Mustangs; the team’s co-drivers absent this weekend with overseas commitments.
Murphy started the session in Fabian Coulthard’s car before switching to Scott McLaughlin’s, in which he eventually set the 15th fastest lap.
The session ran largely without incident, apart from an unusual trip across the grass from Jonathon Webb on the run to Turn 13.
“I definitely can’t do two things at once – I was looking down and playing with bars and a few other things, looked up and realised I had run out of road so yeah I’ll steer clear of that one next time,” Webb laughed.
“The camera is hardly on us and the one time I make a mistake it’s looking right at me but it’s all fun and games.”
Two 30-minute sessions for the full-time drivers will complete the opening day of Supercars action at the OTR SuperSprint.
