Harragon captained the Knights to the 1997 ARL premiership title in a grand final against Manly-Warringah Sea Eagles, despite suffering from serious headaches and seizures throughout most of the season.[3]
Harragon excelled at the State of Origin level, making 20 consecutive appearances for New South Wales between Game I 1992 and Game II 1998. He holds the record for the second most consecutive Origin games by a New South Welshman (Danny Buderus played 21 consecutive State of Origin games between game I 2002 and game III 2008), and most appearances by a NSW forward.
Between 1992 & 1998, Harragon was a frequent choice to play for the Kangaroos. During the 1992 Great Britain Lions tour of Australia and New Zealand, he helped Australia retain The Ashes. All up he scored three tries while representing his country. He missed the 1995 World Cup final due to injury, with Gary Larson being flown in to replace him. That year it was reported that Harragon would receive $1.2 million to secure his loyalty to the Australian Rugby League in addition to $700,000 per season for the next three seasons.[4]
In 1996, he captained the team in a World Cup Test against South Africa,[3] and in 1997 he played in a match against the "Rest of the World".[5]
In 1999, Harragon participated in the first rugby league game to be played at Stadium Australia. Later that year, after playing 169 first grade games in a career lasting ten years, Harragon retired due to an ongoing knee injury mid-season.
Post-playing
Harragon has since become a media personality, working for local Newcastle station NBN Television, before joining Channel 9 as a member of The Footy Show panel (on which his "That's Gold" segment became immensely popular), and as a rugby league commentator. Following format changes to the programme before the 2009 season, Harragon decided to leave the production.[6]
Harragon was also a director of and is a life member of the Newcastle Knights, and is spokesman for NIB Health Funds and Subway.
