Eadie was selected to the Australian team for the 1973 Kangaroo tour and, after an injury to Kangaroos Captain-coach 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.
