The fourth event on the Shannons SpeedSeries calendar concluded with thrilling racing and title-impacting moments at the LIQUI MOLY GT Festival Queensland.
GT World Challenge Australia powered by AWS
It was a title-shifting second race for GT World Challenge Australia powered by AWS, as the Geyer Valmont Racing by Tigani Mercedes-AMG GT3 Evo of Brendon Leitch and Sergio Pires took the victory.
The duo took full advantage of a door latch problem on the series leading Kelso Electrical/Team MPC Audi R8 LMS GT3 Evo2 of Broc Feeney and Brad Schumacher, who finished two laps down in 13th.
Leitch and Pires now hold a nine-point advantage heading to Hidden Valley Raceway.
Previous Bathurst 1000 winner Luke Youlden again shared the spoils of GT Trophy victory alongside Nathan Halstead in the AED Consulting by Tigani Porsche 911 GT3R.
Monochrome GT4 Australia
The reigning Silver Cup winner fought back as Tom Hayman and new co-driver Jett Murray took their first victory as a partnership driving the Method Motorsport McLaren Artura GT4.
Silver-Am Cup was won by Caleb Paterson and Scott Green driving the Norganic Proteins Porsche 718 Cayman GT4 RS CS, while Glenn Walker completed a perfect comeback from an incident in Race 1 to secure Am Cup honours in the Gommersall Motorsport Ford Mustang GT4.
Motorcraft Mustang Cup Australia
A new winner in Motorcraft Mustang Cup Australia was welcomed after debutant Oli Wickham took victory in the Johnson Cup.
It was a Shaw and Partners Financial Services 1-2, with Jack Perkins second and Josh Trappett leading the RM Race Cars effort behind after fighting off Joe Fawcett.
John Goodacre won the Dark Horse Legends class, repeating the effort from Saturday.
Wickham also took the Dark Horse Junior category.
Radical Cup Australia
Chris Reindler and Bryce Moore repeated their result to take the final win of the LIQUI MOLY GT Festival Queensland event.
