In 2003 he moved up to the British Formula 3 Championship with Alan Docking Racing but an enforced mid-year change of teams to Menu F3 did not help his campaign.

By mid-November 2005, Davison had been signed as a full-time driver for Dick Johnson Racing, set to pilot the team's No.

He recorded only modest results, with a fourth place with team-mate Steven Johnson at Sandown being his lone highlight.

In the 2007 endurance races, Davison partnered with Steven Johnson for the third straight year, with the duo scoring a third place at Bathurst.

[5] In 2010, Davison continued with HRT, but technical issues and bad luck plagued him throughout the entire year and he finished the championship in 22nd place.

However, after a stroke of bad luck in the endurance races, despite scoring his maiden Bathurst 1000 pole position, Davison only managed to finish fourth overall.

[7] Driving a Mercedes-Benz E63 AMG, he finished 14th in 2014 and 15th in 2015, collecting just one win, at the 2015 Ubet Perth Super Sprint, and six top five results.

In both years, Davison drove with his brother Alex in the Enduro Cup, narrowly missing a Bathurst podium in 2014.

[10] After a lean patch in the middle of the year, Davison returned to form at the Enduro Cup, finishing third at Sandown with Jonathon Webb.

[12] Davison has competed multiple times in the Bathurst 12 Hour, with a best result of 3rd in 2014 in an Erebus Motorsport-prepared Mercedes-Benz SLS AMG.

His stepgrandfather Tony Gaze was a decorated fighter pilot in World War II and also a Formula One driver.
