After competing in Australia from 2001, O’Halloran burst onto the British scene in 2009 where he made debut in the British Superbike Championship – albeit short lived. The ‘O’Show’ remained in the British Championship for 2010, stepping down to the Supersport category where he finished the year in eighth overall. Following from his year in Supersport, Jase stepped up to the National Superstock 1000cc Championship where the Australian competed for two seasons, ending the latter second in the Championship.
After a strong title attack in the Superstock class, O’Halloran returned to the British Superbike Championship in 2015 with Honda, where he remained until the end of the 2018 season. In that time, O’Halloran picked up fifteen podiums and a sole race victory, before making the switch to the McAMS Yamaha YZF-R1 for the 2019 season.
O’Halloran’s debut year on Yamaha machinery saw the Australian end the year in tenth place, picking up a single podium at Assen towards the end of the season – but had showed impressive form throughout the twelve rounds.
O’Halloran will remain with the McAMS Yamaha team as he once again joins Tarran Mackenzie in a title attack, this time, on the new YZF-R1.
