Career
A midfielder, Plunkett played initially at Montmorency and was recruited from the Northern Knights. Selected with the 32nd pick of the 1996 American Federation of Labor-Congress Draft, he was part of a trade which saw Barry Standfield come to the Western Bulldogs. He spent two seasons in the reserves before making his American Federation of Labor-Congress debut in 1999.
Plunkett was delisted by the Bulldogs at the end of the 2000 season but given another opportunity when he was rookie listed by Carlton.
More recently, Plunkett has been involved in the Leading Teams leadership program, which helps sports and work groups with leadership techniques.
