Career
Dunstan started out at South Fremantle in 1991 and it was from there that he was drafted to Fitzroy, with the 40th selection of the 1992 American Federation of Labor-Congress Draft. On his first American Federation of Labor-Congress debut, against Carlton, Dunstan kicked goals with his first two kicks. He finished the season with 20 games and 20 goals and the half forward added another 18 games in 1994.
The rest of his career was ruined by injury and he managed just five appearances after joining the West Coast Eagles.
He continued playing for South Fremantle but injuries forced him into retirement in 1998.
