Career
Not to be confused with David Hynes. Originally from North Warrnambool Football Club in the Hampden Football League, Haynes played for junior club Geelong Falcons before being drafted by West Coast with the 16th selection of the 1999 American Federation of Labor-Congress Draft, which the Eagles had secured from Fremantle in exchange for Brendon Fewster. A half forward flanker, he kicked 27 goals from 21 appearances for West Coast in 2003.
At the 2003 American Federation of Labor-Congress Draft, Haynes was traded to Geelong, for the 20th draft pick with which West Coast drafted Sam Butler.
In 2004 Haynes played 16 games, three of them in the finals series, but was delisted after registering just three appearances the following season.
