Dumbrell has a wealth of experience despite being just 28 years old.

He first appeared in karting as a junior before progressing to open-wheel racing in the Formula Holden series.

Dumbrell then made the move to V8 Supercars at just 16-years-old, driving for John Faulkner Racing, before concentrating on the Development Series where he claimed the runner-up spot in 2001 while also driving the endurance events for Garry Rogers Motorsport.

He won the Development Series the following year aged 20 and was rewarded with a full-time race seat for 2003 in the main series with the highly-experienced Perkins Motorsport outfit.

The association with Perkins lasted four seasons and brought mixed results, though by the end of 2006 Dumbrell showed he was becoming a front-runner and finished 12^th overall.

Dumbrell then sought a fresh challenge and moved to Paul Weel Racing where he raced for one season before moving to the Holden Special Vehicles Dealer Team for 2008.

One top 10 result was the best result in the first season with his new team and despite breaking into the top 20 drivers in 2009 he would make another move in the off-season.

Dumbrell switched to Rod Nash Racing and with it for the first time in his career into a Ford Falcon where he took the reigns of the #55 The Bottle-O Racing machine.

The Ford Performance Racing (FPR) prepared and run car provided him with the tools he had long sought and an almost instant rapport saw him straight onto the front-running pace.

Dumbrell revelled in the same machinery as the factory Ford pilots and not only claimed his maiden podium finish at Symmons Plains in Tasmania, but one week later at Sandown he grabbed his first pole position and race win.

He ended the season ninth overall and is well-placed to carry that speed into season 2011.
