Born in Narrabri in north-central New South Wales on 24 January 1982 and growing up in Wee Waa, New South Wales, Lyon played junior rugby league for the Wee Waa Panthers. Selected to play for the Australian Schoolboys team, while attending Parramatta Marist High School he was part of the 1999 squad who went undefeated in their tour of France, Ireland and England. Parramatta Eels' club development officer at the time, Noel Cleal, saw potential in the young centre and managed to lure Lyon to sign with the Sydney club.
