Originally from
Ipswich, Coyne was a part of Canberra's competition-winning side of the
1989 and
1990 seasons. Coyne also played for the club in two further grand finals which both ended in defeat which were the 1987 and 1991 deciders. In the 1989 post season, he travelled with the Canberra club to England for the
1989 World Club Challenge which was lost to
Widnes. He also played in two
Test matches for
Australia in 1991 and 11
State of Origin games for
Queensland between 1989 and 1992. Coyne was named a member of Canberra's 25-man "Dream Team" in 2007, as part of the club's 25th anniversary of their entry into first-grade rugby league. In the 1991 semifinal against the
Manly-Warringah Sea Eagles, Coyne went over for his 4th and final try of the match after Canberra legend Mal Meninga took a tap instead of the expected shot at goal. Manly were stunned and seen out of the 1991 season. Meninga can be seen casually approaching Coyne and suggesting something as the Manly players walk towards the posts, backs turned. ==Post playing==
