In 2007 he joined the Glenmore Bulls U17 team and finished the season as the runner up in the best and fairest award. The following year he moved to Brisbane to join the Zillmere Eagles senior team for the 2008 QAFL season. Midway through the season he had to choose whether to accept an offer from the newly formed GC17 team or to elect for the 2008 AFL Draft. Despite playing less than 20 games of football at any level, Smith received letters of drafting interest from Collingwood, Hawthorn, Geelong, North Melbourne and Port Adelaide while Richmond football manager Craig Cameron paid him a visit at his Brisbane home.
In August 2008 he was the fourth player to sign for the Gold Coast Football Club as a Queensland zone selection and played for the club in the 2009 TAC Cup season where he was selected as first ruck in the TAC Cup Team of the Year. He played all but one game in the 2010 VFL season and was named in the AFL Queensland Team of the Year, the only VFL player selected.
Smith made his debut in round 2, 2011 in the Gold Coast Suns inaugural AFL match against Carlton at The Gabba. In the same game, Smith scored Gold Coast's first ever behind in the AFL, which also happened to be the Gold Coast's first ever point in the AFL.
In round 5, Smith was part of the first Gold Coast Suns victory over Port Adelaide at AAMI Stadium. He has 18 hitouts and kicked a goal.
