‘The White Hordes From the West’: Race and Refuge in Australian Media Commentary About White Rhodesians During Zimbabwe's Decolonisation

Australian Journal of Politics &History, EarlyView.
ABSTRACT This article explores Australian media commentary on white Rhodesians migrating to Australia, focusing on the period of Malcolm Fraser's prime ministership (1975–1983). The main argument is that the Australian media debates about whether to classify white Rhodesians as ‘migrants’ or ‘refugees’ were not merely semantic but reflected a deeper ...
