Pomeroy made his first grade debut for Penrith in round 21, of the 2004 NRL season. After only sporadic NRL appearances for Penrith, Pomeroy signed with the Cronulla-Sutherland Sharks in 2006. A serious groin injury that year limited his appearances on the field for Cronulla to eight games. In 2007, he became a regular at centre in the run-on side and scored his first hat-trick of tries in Round 6.[5]
Pomeroy played with Cronulla up until the end of the 2013 NRL season. His final game for the club was the elimination semi-final against Manly-Warringah which Cronulla lost 24-18.[7]
Pomeroy was highly regarded at the club for being one of the most consistent players during Cronulla's poor run of form from 2009 – 2012. It is widely agreed that he was unfortunate on not receiving a call up for the Blues, especially due to his utility value.
Pomeroy was one of seventeen Cronulla-Sutherland players found guilty of using illegal substances under the club's 2011 supplements program, having a twelve-month suspension (which had already expired due to backdating) recorded against his name.[11]
Representative career
Pomeroy was selected on the bench for City Origin in 2007 and was also named in the City side in 2008. Later this same year, his successful season was rewarded with selection in the Prime Minister's XIII side to play the Papua New Guinea Kumuls.[12]
