ABSTRACT
Where the scientists trod, the diplomats followed. The immediate impetus for the Antarctic Treaty was Australia's concern that the Soviet Union, which had stations in its sector, would stay on and announce a sector claim after the International Geophysical Year (IGY) had ended. At a meeting of Australia, New Zealand, and the United States (ANZUS) in September 1955, Australian Minister R. G. Casey said that Soviet plans for regular flights to Antarctica were "most menacing." When U.S. Secretary of State John Foster Dulles visited Australia in March 1957, Casey asked him to do something about Antarctica's political situation for the period following the IGY. 1
