Nash began his career in South Australia, where he played for the Central District Football Club. In Junior Football he played for The Nuriootpa Rover Football Club (Tigers), in The Barossa Light & Gawler Football Association.
In Essendon's round 16 win against Collingwood in 2005, defender Andrew Welsh was unable to take his place on the field. Nash was called in to replace him only hours before the match was scheduled to begin and he was lined up against Collingwood's captain Nathan Buckley.
Nash played 43 games and kicked ten goals during his career at Essendon. He played a career high 18 games in the 2008 season, but only 2 games in 2009, as he struggled with foot injuries.
On 8 October 2009, Nash was traded to the Port Adelaide Football Club in a four team deal, which included Shaun Burgoyne. Nash made his Port Adelaide debut against the Melbourne Football Club in 2010. He was delisted by the club at season's end.
