[1] With sponsorship from Wynn's and OAMPS Insurance, Davison upgraded to a year old Van Diemen RF98 for 1999[2] and finished third in one of the most competitive Australian Formula Ford seasons behind champion Greg Ritter.

Unable to break into an open-wheel series, Davison found a role with German Sports Car team Manthey Racing.

In 2008, an opportunity to return to Europe beckoned and Davison took up a drive with Team Felbermayr-Proton in the 2008 Le Mans Series season.

Despite not winning a single race, Davison and co-driver Marc Lieb finished runner-up in the GT2 class in their Porsche 997 GT3-RSR behind Ferrari F430 GT2 driver Rob Bell.

In 2016, Davison once again entered the Australian Carrera Cup Championship full-time, winning two of the first four rounds at Albert Park and Hidden Valley Raceway.

[4] Davison's Carrera Cup form led to him join the Perkins Motorsport V8 Supercars team for the 2004 endurance races, sharing Tony Longhurst's regular season car with Jamie Whincup.

He did, however, achieve his maiden pole position on his return to Hidden Valley, but a potential podium finish was scuppered by an electrical failure.

Davison improved to finish 11th in the 2011 season, including his second career podium at the opening race of the year at the Yas Marina Circuit in Abu Dhabi.

[10] After James Courtney's departure from Team Sydney by Tekno, Alex was drafted in by Jonathon Webb to drive the #19 Local Legends Holden ZB Commodore from the Eastern Creek Round onwards.
