Clarke made his first grade debut for Balmain in Round 16 1984 against
Manly-Warringah at
Brookvale Oval. In 1985, Balmain finished second on the table but were eliminated in consecutive weeks during the finals series. Clarke played a total of 24 games for Balmain in 1985. Balmain would go on to be a constant feature in the finals series over the coming years. Clarke missed both the 1988 and 1989 grand final defeats through injury. In 1990, Clarke joined Penrith and was a member of their first ever grand final side. Penrith would lose to Canberra 18–14. In 1991, Penrith would reach their second grand final in a rematch against Canberra. Clarke played at prop as Penrith came from behind to win their first premiership 19–12 at the
Sydney Football Stadium. After winning the 1991 premiership, Penrith's fortunes declined and the club failed to reach the finals in the following seasons. In 1994, Clarke signed with the
Parramatta Eels. Clarke played two seasons for Parramatta as the club struggled towards the bottom of the ladder narrowly avoiding the wooden spoon in 1995. Clarke retired following the conclusion of the 1995 season. ==References==
