After competing in Australia from 2001, O’Halloran burst onto the British scene in 2009 where he made his 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 shown impressive form throughout the twelve rounds.
2020 gave O’Halloran his best chance at the BSB crown, narrowly missing out by 21 points at the final round, the Aussie rider did record his best season to date. Three wins and a further eight podiums mean the ‘O’Show’ is a firm contender for the 2021 BSB championship as he competes with the McAMS Yamaha Team for a third year running.
After a dominant opening half of the season, Jason O’Halloran secured third in the 2021 Bennetts British Superbike championship, taking 11 race wins and 22 podium finishes.
