Cameron Waters led a Mercedes-AMG sweep of the top four positions in the final practice session prior to qualifying for the Repco Bathurst 12 Hour.
Waters, in the No. 222 STM Motorsports Mercedes-AMG GT3 Evo, recorded a best time of 2:02.919 in the closing seconds of the 60-minute scheduled session.
It was 0.256 seconds quicker than the No. 888 Triple Eight Race Engineering Mercedes-AMG of Broc Feeney, with the sister Triple Eight machine of Jordan Love ending up third.
Ross Gunn, in the No. 27 Heart of Racing by SPS Mercedes-AMG was fourth, with Kelvin van der Linde the best of the rest in the No. 22 Melbourne Performance Centre Audi R8 LMS GT3 Evo II in fifth.
Alessio Picariello, Lee Holdsworth, Valentino Rossi, Jules Gounon and Sheldon van der Linde completed the overall top-ten.
The session began with a practice run of the new Full Course Yellow procedure and ended with a dramatic accident by the No. 50 KTM XBow GT2 of Trent Harrison at the top of the mountain.
An initial red flag came out with 37 minutes to go for an accident by the No. 20 T2 Racing IRC GT Invitational class car of Adam Hargraves.
Both cars appear unlikely to participate in any further action today.
