In the summer of 1919, Sawyer and his family moved to Brisbane, Australia, to head the Rockefeller Foundation's new hookworm control campaign there. Early in 1920 he spent several months visiting the campaign's regional sites and surveying other possible sites. Visiting the mining town of Broken Hill in western New South Wales, Sawyer was surprised to find an Afghani pack train carrying goods to outlying areas..
