Since the Bathurst 12 Hour race was changed to allow FIA GT3 cars in 2011, Lowndes has been a regular competitor in the race. In 2011 he finished second outright in an Audi R8 LMS GT3 driving for famed German endurance racing team and multiple 24 Hours of Le Mans winners Joest Racing. In 2012 he failed to finish, again driving an Audi R8, this time for another German team Phoenix Racing, while he also failed to finish in 2013, again in an R8.
