Jamie Whincup snatched the Armor All pole position for Race 4 following last gasp effort in a wet qualifying session at Symmons Plains.
Prolonged heavy rain at the 2.4km circuit delayed qualifying by 20 minutes as officials assessed the condition of the track.
It proved to be another incident-filled session once action got underway with Triple Eight and DJR Team Penske going head-to-head in the closing stages.
Whincup saved his best until the final moments as he secured his 74th career pole from the Shell Ford of Scott McLaughlin with a 58.39s effort.
McLaughlin, who ran off the road at Turn 6 earlier in the session, had held provisional pole as the chequered flag flew, but had to settle for second.
“It’s crazy conditions. I just pushed hard, on the limit under brakes everywhere,” said Whincup.
“It’s critical to be up the front, obviously pole’s fantastic but to be in the top five is critical.”
Prodrive Racing Australia’s Chaz Mostert secured third on the grid ahead of Brad Jones Racing’s Tim Slade in the repaired #14 Commodore.
Reigning champion Shane van Gisbergen could only manage fifth in the sister Red Bull Holden with the second DJRTP Ford of Fabian Coulthard sixth.
The top 10 was completed by Todd Kelly (Nissan), Craig Lowndes (Triple Eight), David Reynolds (Erebus Motorsport) and Cameron Waters (Prodrive).
Mark Winterbottom could only manage 12th position in his #5 Prodrive Falcon.
Several cars ran off the road during the session including Lowndes and Dale Wood. The pair both enjoyed spells at the top of the timesheets.
The session was red flagged after five minutes when Alex Rullo found himself beached in the Turn 6 gravel trap in his rebuilt Lucas Dumbrell Motorsport Commodore.
Only 22 cars took part in the session following the withdrawals of James Courtney (Mobil 1 HSV Racing), Taz Douglas (Lucas Dumbrell Motorsport), Will Davison (Tekno Autosports) and Rick Kelly (Nissan).
Race 4 (84 laps) is due to begin at 1405 local time.
