Hart captained North Adelaide to the 1987 premiership, under coach Michael Nunan, the same year that he represented Australia in an International Rules series against Ireland.
He was a premiership player again in 1991, with a Jack Oatey Medal winning seven-goal haul in the 1991 Grand Final.
Hart was recruited by Adelaide in 1991 for their inaugural AFL season and played 18 of a possible 24 games that year, including their opening round victory over Hawthorn.
He was also a regular in the team the following season and kicked six goals at the Melbourne Cricket Ground when Adelaide convincingly best Richmond by 110 points in round 20.
Hart then coached the club from the sidelines in 1995 before returning for one final stint from 2001 to 2003, which ended after an 108 point belting in Round 16 to an equally struggling South Adelaide.
