|Rugby union career|
Discovered in 1993 by GoldRats Rugby Union Club of Southern Cross University, Lismore, New South Wales while studying coastal and fisheries management, he then moved onto the Tuggeranong Vikings Rugby Union Club in Canberra, he made the 1994 Australian Capital Territory (ACT) Under-21s and then the Australian Universities team. The following year, he played in the Australian U21s team and made his debut for the ACT against New South Wales B. He made his Super 12 debut with the Brumbies in 1997.
He made his international début as Australia took on the British and Irish Lions in the third and final test of the 2001 series; at the time Harrison was a student studying for a Bachelor of Applied Science in Sports Administration at the University of Canberra from which he graduated in 2001.
As of 23 May 2006, Harrison had played 25 games for Ulster, 19 of those in the Celtic League and 6 in the Heineken Cup. Harrison proved an effective player in the Celtic League, a consistent winner of line-out possession and aggressive in rucks and mauls. Although regarded as inspiring by other Ulster players, his tendency to indulge in sledging led to confrontation with a number of opposing players and a number of off the pitch incidents.
On Monday 30 November 2009, it was announced that Justin Harrison would return to play for the Brumbies in 2010 on a one-year deal, as coverage for Peter Kimlin. However, the ARU has not endorsed this contract.
- Harrison has been the cause of much controversy over his career. He used racial slurs towards South African winger Chumani Booi in 2005 while playing against the Cats of South Africa.
- On 20 May 2009 Harrison left Bath after requesting an early release from his contract. The 35-year-old's exit came two days after the club launched an inquiry into an alleged incident involving Bath players at a London nightclub. Later the same day he announced his immediate retirement. The RFU announced on 17 June that he and three other players would face an RFU disciplinary panel charged with "conduct prejudicial to the interests of the game". Harrison admitted to taking cocaine and fighting with a member of the Harlequins playing staff. He was banned from playing and coaching rugby until 13 January 2010.
