Wicketkeeper-batsman Niall O’Brien is no newcomer to the world of Australian cricket, having gained valuable experience by playing grade cricket with Mosman and North Sydney in the early stages of his career. His international journey began with Ireland in 2006 when he made his debut in a one-day international match against Scotland. O’Brien played an integral role in Ireland’s remarkable performance during the 2007 Cricket World Cup, contributing significantly to their upset victory over Pakistan with a score of 72. He continued to impress during that tournament, notching up 63 runs against England. In the 2011 edition, he played in six matches and showcased his prowess with a top performance of 57* against Netherlands. In 2015, O’Brien marked his third appearance at the World Cup with a series of confident displays. His strong form during Ireland’s warm-up tours in Australia, New Zealand, and Dubai set the stage for his upcoming World Cup campaign. Notable innings included an 88 against the Australian Capital Territory, 55 against Canterbury, and a solid 68 against New Zealand A. Furthermore, in January 2015, he achieved a career-best with an unbeaten 80* against Scotland.
