Wynne started his career at West Perth where he was a centre-half forward and played in their 1969 premiership team.
In the 1978 SANFL Grand Final they had trailed Sturt by 29 points at three quarter time but came back to win, with Wynne kicking the goal which put them in front.
In his first seasons with the recently christened "Falcons", a policy of developing youth saw the club play finals for only the second time since 1978,[4] but with crippling injury problems West Perth failed in the first semi-final against the experienced Swan Districts, led by a devastating display from Garry Sidebottom.
[5] 1986 was disappointing, with the Falcons winning only nine games plus a draw, and Wynne was replaced by Bruce Monteath for the 1987 season.
Aside from representing Western Australia at the 1969 Adelaide Carnival and South Australia at the 1972 Perth Carnival, Wynne had earlier played for his country at International rules football in the Australian Football World Tour of 1968.
