Drafted by West Coast with pick 45 at the 2012 National Draft,[5] Colledge made his senior WAFL debut in round 5 of the 2013 season, but managed only one further senior WAFL game (and six reserves games) after struggling with various injuries, including hip problems during the pre-season, a broken jaw, a hamstring injury, and finally a season-ending ankle injury.[6][7] After playing the first two games of the 2014 WAFL season for West Coast's new reserves affiliate, East Perth, he made his senior debut for West Coast in round three of the 2014 AFL season, recording eight disposals and four tackles against St Kilda. He returned for the next game, against Geelong, but was then dropped and played only at WAFL level for the rest of the season.[8][9]
During the 2015 AFL season, Colledge made only a single appearance at senior level, against Geelong in round nine. He was delisted at the end of the season, but was re-drafted in the 2016 Rookie Draft due to being contracted for 2016.[10] Colledge was unable to break through to the senior line-up during the 2016 season, and was delisted once again.[11]
