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.
