He debuted for the Australian cricket team in 2002, playing his first one-day international against South Africa. While he has become a regular member of the one-day squad, Watson has played few Test Matches for Australia, having debuted against Pakistan at the Sydney Cricket Ground in January 2005. Despite being allocated to be Australia's designated Test all-rounder, injuries have often prevented him from claiming his position in the Test team. However, from the second half of 2009, Watson has acted as Australian Test opening batsman, along with Simon Katich. Watson was awarded the 2010 Allan Border Medal.
Watson's wife Lee is a Fox Sports Australia presenter. He has participated in several modelling shoots, such as the 2009 & 2010 Men of Cricket calendars and a shoot for Alpha Magazine.
