Other expeditions included three medical relief expeditions to assess the health of Aboriginal people in South Australia - one in 1919 and two in 1920 - which Basedow led. Basedow also participated in two vice-regal expeditions to central Australia: one in 1923 organised by Sir Tom Bridges, Governor of South Australia, who was keen to build a north–south railway to open up central Australia; and one in 1924 involving Lord Stradbroke, Governor of Victoria. Basedow also participated in expeditions funded by wealthy pastoralist Donald Mackay to central Australia in 1926 and Arnhem Land in 1928.
