Whitaker began his professional playing career in 1997 as a scrum-half for the Waratahs, where he remained for ten seasons. He also played for Australia, but his Test career was constrained for many years by the incumbent scrum-half and captain, George Gregan. As such, he got minimal international game time but was in the match-day squad for many a year. He captained the Wallabies in a World Cup match against Namibia in Adelaide in 2003. In 2006 Whitaker moved to Ireland where he played four seasons for Leinster before hanging up the boots and taking up coaching.
Whitaker joined Super Rugby side the NSW Waratahs in 1997, and gained his first Australian cap the next year. He played a total of 31 games for Australia and scored 10 points.[citation needed] Whitaker left the Waratahs in 2006, and joined Leinster Rugby in Ireland. He won the Celtic League in 2008 with Leinster before winning the Heineken Cup as vice-captain with the side in May, 2009.[citation needed] The final was, in fact, his last professional game before retirement.
