with Campbelltown Kangaroos claiming the inaugural premiership undefeated. Eleven first grade teams were divided into north and south divisions, with the winners of each divisions meeting in a grand-final. Bowral Blues and Mittagong Lions would dominate these years. Picton Magpies would win the Group's first ever Clayton Cup with an undefeated season in 1966 under the captain- coaching of Billy Peel. The Magpies were on track to go back-to-back in 1967, entering the 1967 decider undefeated. However, in one of the Group's biggest ever boilovers, the John Cole inspired Mittagong Lions rolled the black 'n whites, denying Picton a certain back-to-back Clayton Cup. 1969–83: Campbelltown City Kangaroos. One of the CRL's Greatest Clubs Dominates This period marks the era of the Campbelltown clubs. The rapid expansion of the Sydney metropolitan area saw a population boom in the Campbelltown area. New suburbs brought new clubs. After Campbelltown Kangaroos defeated the Bowral Blues 22–3 in the 1969 Grand Final, two new clubs were formed- the Campbelltown RSL Warriors and Campbelltown Collegians. Captain- coached by former St George Dragons hooker Ray Corkery, the Kangaroos would win three successive Group 6 premierships- defeating Oakdale Workers in 1970 and the RSL Warriors in 1971. Now known as the Campbelltown City Kangaroos, the club started to enshrine its Group 6 dominance with the construction of a Leagues Club to finance its League teams. This club has now morphed into Wests Leagues Campbelltown. Contending for 4 straight premierships in 1972, the Roos were controversially defeated by Camden in the major semi final of that year. The RSL Warriors would go on to defeat Camden in the 1972 Grand Final. Campbelltown City soon struck back though with the signature of Canterbury & Australian test centre Johnny Greaves. Greaves, possibly the best player the Group has seen, captain- coached the 'Roos to another treble- defeating Campbelltown Collegians in 1973 and Ingleburn Bulldogs in 1974 and 1975. The Oaks would win their first premiership with a dogged 16–10 victory in the 1976 decider over Camden Rams. Captain- coached by the mercurial Les Williams, the Tigers had a week earlier thwarted City's attempts to become the first Group 6 club to win 4 consecutive premierships. Williams' men would repeat the dose in 1977 with a 22–3 thumping of Camden again. These years would prove bitter sweet for the Camden club, losing all 3 grades on Grand Final day in 1976 and
