Educated at Marden High School, Greg Thomas was an elusive rover/forward/wingman, who was particularly dangerous around the goals.
In 1979, Thomas played 16 games for the Norwood Under 17's. He had an outstanding season in 1980, being named vice-captain of Norwood's Under 17's and playing in all of the possible 22 matches. As well as winning the team's best and fairest award, Thomas was also the recipient of the coveted McCallum Medal - awarded by the SANFL for the best player in the U/17's competition.
Progressing to the Under 19's in 1981, he played 22 out of a possible 23 games and kicked 43 goals.
Thomas made his League debut against West Adelaide in round 4, 1982. He played 23 games for the 1982 season, kicked 37 goals and had the distinction of playing in a premiership in his first year of senior football.
Named in a forward pocket in the 1984 Grand Final, Thomas was one of Norwood's best players in its Grand Final "History-Makers" win, against arch-rivals Port Adelaide. Thomas made 16 appearances in 1984, reaching his 50 game milestone late in the season.
After playing 19 games the following year, he only managed five in 1986. After two Escort Cup appearances early in 1987, and struggling to gain a regular spot in the League side, the dual-premiership player decided to move to Central District, where he added another 19 games in 1987.
