Smith competed against Josh Thomas, Chloe Maxwell and Prue MacSween on the episode which aired in December 2012. Throughout 2012 and 2013, Smith was a regular contributor to Network Ten's discussion program Can of Worms. In June 2013 Smith was announced as one of the four original presenters of the Seven Network's new early afternoon infotainment program The Daily Edition, hosting the show alongside Tom Williams, Monique Wright and Sally Obermeder. Smith continued in this role until it was announced he would be scaling back his commitments to the program from January 2015. It was revealed in January 2017 that Smith would be one of the contestants to compete on the third series of Network Ten reality series, I'm a Celebrity...Get Me Out of Here!. Smith was the fourth celebrity to be eliminated from the competition. His nominated charity was White Ribbon Australia, having revealed on the show he was once the victim of domestic violence. Smith guest hosted Network Ten lifestyle program The Living Room in 2018. Also that year, he was one of the celebrities who took part in the Seven Network's The Real Full Monty. In early 2019, it was reported that Smith had teamed up with three of his The Real Full Monty castmates to film a new travel comedy show for the Seven Network called Mates on a Mission. In August 2019, Smith appeared on a celebrity edition of The Chase Australia alongside Lisa Curry, Brendan Jones and Ricki-Lee Coulter.

Smith was representing Challenge.
