In 1964, the International Stoke Mandeville Games Committee (ISMGC) held a meeting of managers and trainers in Tokyo, Japan. This meeting resulted in the enlargement of the number of nations represented by the organisation. Bedbrook nominated Australia for inclusion and the organisation's constitution was modified to include Australia alongside Argentina, Germany, Japan, and Rhodesia. This also resulted in Bedbrook becoming a member of the ISMGC that year. In 1967m the ISMGC set up a Medical Sub-Committee. Bedbrook was the first chair of this committee. In 1972, Bedbrook was replaced by Doctor J. Grant on the ISMGC. In 1964, Bedbrook served as the Australian team leader at the Paralympics. At the 1968 Tel Aviv Paralympics, Bedbrook served as the Australian SMGF Delegate.
