Graeme Langlands, took over as Test fullback for the final two Ashes tests against Great Britain, marking his début at Headingley in Leeds by kicking 5 goals in windy conditions. Though Langlands regained the test fullback spot in 1974, Eadie went on to be Australia's regular fullback from 1975 until he retired from representative rugby league following the experimental 1980 State of Origin match. Despite being a record point scorer for Manly, Eadie was never a prolific point scorer at Test or State representative level as Country Firsts and later Parramatta Michael Cronin was generally the first choice kicker in representative sides. In 1974, Eadie won the Rothmans Medal as Sydney rugby league's best-and-fairest player, and at the end of the controversial 1978 finals series he produced one of the finest performances ever by a fullback in the Grand Final replay, "where he single-handedly destroyed Cronulla-Sutherland by scoring a try, setting up two others for Russell Gartner and kicking three goals and a field goal". Two years earlier, his accurate goal kicking under pressure won Manly the 1976 Grand Final where they scored only one try to Parramatta's two. Eadie's dominance in the '76 and '78 Grand Finals was recognised thirty years later with the awarding of retrospective Clive Churchill Medals for Man of the Match in those games. In 1977, Eadie was Australia's first choice fullback for the 1977 World Cup and played in Australia's 13–12 win over Great Britain in the World Cup Final at the Sydney Cricket Ground. Following the 1978 Grand Final, Eadie was selected to his second Kangaroo Tour. The coach of the 1978 Kangaroos was Eadie's Manly coach Frank Stanton, while the captain was his former long time Sea Eagles teammate Bob Fulton, who was at the time playing for Eastern Suburbs. Eadie played fullback in all 5 test matches on the tour with Australia defeating Great Britain 2–1 to win The Ashes, but surprisingly lost the test series to France 2–0. He also played in the non-test international against Wales at the St. Helen's Rugby Ground in Swansea with Australia winning 8–3. Despite Manly declining in surprising fashion to miss the semi-finals for the first time in twelve years in 1979, Eadie's form remained excellent and he played in all 3 Ashes tests against a very lackluster touring Great Britain side. He then went on to play in the inaugural State of Origin
