Early life

Dumas was born in Taree, New South Wales, Australia.

2003

Dumas originally was signed to the Cronulla side and gradually worked his way through the grades at the club, making his first grade debut in 2003.

2004–2005

Dumas played several games in the 2004 season impressing many with his hard hitting tackles and shoulder charges similar in nature to Sonny Bill Williams, his aggressive defence earned him a call up to the French international sevens side with teammate Dimitri Pelo. After an impressive start to his 2004 season he became injured with a serious season ending neck injury and he never was able to retain his spot in first grade for Cronulla-Sutherland. Mid-way through the 2005 season he left the club and signed for the Sydney Roosters.

2006

Dumas played in the 2006 NSW Cup grand final for Newtown who were the Sydney Roosters feeder club at the time against Parramatta. Newtown would lose the grand final 20–19 at Stadium Australia.^[2]

Later career

Since then, Dumas sacrificed his first grade career to raise a family. He spent several years as a player-coach in the Group Three competition on the Mid North Coast playing for clubs Port City Breakers and Taree City Bulls
