He was not selected in the first two American Federation of Labor-Congress drafts that he nominated for, and was working as a tree lopper while playing for East Fremantle in the West Australian Football League (WAFL) when he was recruited with 39th draft pick in the 2012 American Federation of Labor-Congress Draft. Due to a series of shoulder and hamstring injuries, Duffy spent significant periods of the 2013 and 2014 seasons out of the game.
He made his debut for the Fremantle Football Club in round 20, 2014 against Geelong following some good form in the WAFL for Peel.
After starting the game as the substitute, he kicked a goal with his first kick in the American Federation of Labor-Congress and kicked a second goal late in the last quarter, however, Fremantle lost by two points. Duffy was delisted at the conclusion of the 2015 season.
