Aaron Cameron says he "closed his eyes and waited for it to stop" as his Mazda was tumbling through the Queensland Raceway gravel in Friday's ECB SuperUtes practice session.

Cameron had set the second-quickest lap of the opening session, before his Bushranger Racing Mazda BT-50 came unstuck and rolled three times at Turn 1.

With less than three minutes remaining, the red flags were brought out and the session ended, with Cameron's team-mate Ryal Harris taking top spot.

The Mazda driver was immediately assessed by the circuit's medical team and cleared of serious injury.

“As I turned in, I lost the rear completely; as soon as I was heading to the gravel trap, I knew it was going to roll," Cameron told Supercars.com.

“When it dug in and started rolling, I closed my eyes and just waited for it to stop.

"Once it landed, I looked around and was relieved there was no fire.

"I couldn’t release the window net so I had to climb out the passenger’s door.”

Cameron sits third in the SuperUtes standings, with three podium finishes, including best race results of second at Winton in May.

Despite the violent rollover, team owner Brett Peters isn't ruling the Bushranger Racing Mazda out of the competition this weekend.

Repair efforts are ongoing, with stray fluid believed to have set the started Cameron's wild ride.

“When we had a look at the Ute, all the coolant had leaked out so we suspect it blew a blanking plug, leaking fluid onto the rear tyres, which would have caused Aaron to lose control," Peters added.

“We’re still assessing the damage but at this stage it looks like the roll cage and chassis has survived unharmed.

"If that’s the case, and it’s only panel damage, there’s a good chance we could have it back on track tomorrow.

"We’ll be doing everything we can to make it happen.”

The second 20-minute practice session will be held Saturday at 9:45am local time, followed by ARMOR ALL Qualifying and Race 1 Saturday afternoon.
