No Sugar by Jack Davis tackles a particularly horrific time in Australian history, exploring the Aboriginal experience in the Great Depression throughout the 1930s. The postcolonial context of the play allows Davis to highlight the systematic ways in which the Australian government attempted to displace the Aboriginal peoples from their native land while simultaneously working to eradicate their culture and languages.

Set over a century after the initial British invasion in 1766, the play explores how Anglo-Australians have never accepted assimilated Aboriginals into their culture but have also prevented Aboriginal peoples from inheriting their ancestral culture, thus leaving the Aboriginal peoples of Australia displaced and disorientated.

Through Davis's strong development of voice in No Sugar, the audience is thrust into experiencing this displacement with the use of techniques such as a polyphonic narrative and perambulate staging. Both of these techniques prevent the audience from settling into the perspective of one central protagonist. Instead, the audience's point of view is constantly uprooted and switches across gender, age, and ethnicity. While the focus remains on the Millimurra-Munday family, the audience also witnesses the perspectives of Mr. Neal, Matron Neal, the Sergeant, the Constable, and Neville.

By pivoting from an Aboriginal perspective to that of A. O. Neville, the politician credited with introducing the policy that led to the Stolen Generation, and other white oppressors, Davis creates a disjointed voice intended to mimic the fragmented cultural experience of many Aboriginal people during the 1930s.
