From Rostrevor College, Matthew Twomey was named the Norwood under 17's player of the finals in 1992. The following season Twomey played two games in the under 19's, and four in the reserves. He was one of eight Norwood players who represented South Australia in the National under 17's Commonwealth Bank Teal Cup competition.
In 1994 Twomey continued his progress and played four games in the under 19's and 13 in the reserves.
He was one of Norwood's best players in the 1995 reserves grand final victory over South Adelaide : 19.15 to 7.9.
Twomey made his league debut in round 4, 1996 and played 11 senior games for the season. He was also named the reserves best and fairest and was one of Norwood's better players in the team's loss to Port Adelaide in the reserves grand final.
He made another six senior appearances in 1997, but was dropped after Norwood's second-semi final loss to Port Adelaide.
Despite playing another fine game in that year's reserves grand final, Norwood were again defeated by Port Adelaide - by one point.
A solid and reliable ground player, he was seen predominantly as a ruck-rover or centreman but had difficulty cementing a league spot in the powerful Redlegs side which contained the likes of Andrew Jarman, Richard Kelly and Garry McIntosh.
Twomey decided to join West Adelaide where he had a very successful stay, playing 99 games (1998 to 2002).
The talented all-round sportsman also captained the Rostrevor College First XI cricket team. A right-handed batsman, he played A Grade for the East Torrens Cricket Club
