Amos played junior football for the Burleigh Bears and moved to the North Queensland Cowboys, where he made his first-grade debut in 2006. He then signed for the Gold Coast Titans for its inaugural season in 2007, where he was a regular member of the first-grade team. However, he fell out of the squad in 2008 as Nathan Friend became the side's preferred hooker.[2] He returned to the Cowboys for the 2009 NRL season, signing a two-year deal.[3]
