Supercars champion Scott McLaughlin held off Jamie Whincup by 0.05 seconds to secure the provisional pole for Saturday's leg of the Adelaide 500.
It was McLaughlin's DJR Team Penske Ford team-mate Fabian Coulthard that made a fast start to the session, becoming the first man in the 1m19s with a 1m19.787s on his first proper run.
It only lasted until McLaughlin banked his first flyer, the reigning champion going quickest with a 1m19.598s.
What to watch for as Supercars 2019 begins
That was all it took for McLaughlin. He was up with a couple of minutes to go, confident that the early lap would be enough.
The session decides who makes it into Saturday morning's top 10 shootout pole qualifying, and decides the grid from 11th back.
"For everyone at Ford Performance, all the Ford teams, it's been fantastic," said McLaughlin.
"The Shell V-Power is great for me and Fabian, everything feels pretty good.
"I need to tune up a couple of different areas, but looking forward to the shootout tomorrow.
"It was a bit of a go-back, but there's always something to try.
"We've got a set for the Shootout tomorrow anyway, so good."
Whincup did the lap in the session, running McLaughlin close right at the flag.
Coulthard was third quickest, followed by Nick Percat and the Tickford Mustangs of Cam Waters and Will Davison.
Shane van Gisbergen snuck into the shootout with the seventh quickest time, but it was a close-run thing.
The Red Bull driver was sitting 11th as he started his final lap, and got stuck behind Simona de Silvestro, who was on his own lap and no mood to move over.
Rick Kelly was the sole driver to make the shootout with the eighth-best time. Holden drivers David Reynolds and James Courtney round out those taking part in the single-lap dash on Saturday.
The unlucky man on the bubble was Tim Slade in 11th, while the biggest surprise was Chaz Mostert qualifying just 12th.
Anton De Pasquale will start from the grid, after firing his Erebus Holden into the wall Turn 8 right-hander on his first flying lap.
