Career
He was also a state and national representative, playing four Tests for Australia in 1973. Saint George
Maddison started his first-grade football career with Saint George in 1965 and the following year appeared in his first grand final, the last of the Dragons" record-breaking 11 consecutive premiership wins. In the late 60s after Street George had lost the stars of their long reign, Ken Maddison"s work ethic (along with the stellar brilliance of Billy Smith and Graeme Langlands) was a factor in keeping the club competitive, regularly finishing in the top five.
Maddison played in the 1971 Grand Final loss to South Sydney, again in the centres.
Ken"s younger brother Keith Maddison also played alongside him at the Dragons in six seasons from 1966 to 1971. Cronulla-Sutherland
In 1972 Maddison moved to the young Cronulla-Sutherland club, playing in the second row.
He also scored a personal best eight tries that year before playing in Cronulla"s first Grand Final, the 1973 loss to Manly-Warringah 7 - 10. Although Maddison played at a time when the loose forwards of the Souths" pack - Coote, Bob McCarthy, Gary Stevens and Paul Sait - dominated representative selections, he managed his Australian debut at the end of a great club season in 1973 when he was selected for the 1973 Kangaroo tour.
He was one of the form forwards of the tour scoring two tries in the third and deciding Test against Great Britain.
He played in all three Ashes Tests, in one Test against France and in nine minor tour matches scoring six tries in all. The following year he made his sole state appearance for New South Wales Blues. Maddison continued playing for Cronulla-Sutherland until 1975.
In 2006, he was named at second-row in a Sharks dream team
