Originally from the Modbury Hawks, Heath Grundy played 17 games in 2001 for the Norwood under 17's, and represented South Australia in the National under 16 championships. He was nicknamed "Reg" after the well known Australian television producer Reg Grundy.
In 2002 Grundy was appointed captain of the Norwood under 17's and played another 15 games. He again played for SA in the national under 16 championships and, as a result of his fine form in these championships, was selected in the Australian Institute of Sport/AFL academy squad.
2003 was a big year for Grundy. Still eligible for the under 17's, he started the season in the under 19's. He travelled to Ireland with the Australian under 17 team and, on his return, played for SA in the under 18 championships and made his league debut for the Redlegs.
In 2004, Grundy played 17 league games for Norwood and was recognized with the "Outstanding Qualities Award." During the season he again represented SA in the under 18 national championships and was named vice-captain of the team. At the end of the championships he was selected in the All-Australian under 18 team.
The following season Grundy was chosen by the Sydney Swans in the Rookie Draft, at pick number 42.
Originally more of a forward, Grundy developed into a very reliable defender for the Swans, playing over 250 AFL games (2006-2019) including the 2012 AFL premiership
