The distinction between black and white is pronounced in postcolonial Australia, and the theme of racism marks every interaction between Aboriginals and white Australians throughout the play. Due to their race, Aboriginals are forbidden to drink, walk the streets after dark, move beyond where the government stipulates, or marry without permission. Additionally, they receive less than a third of the welfare that white Australians receive. They are often referred to disparagingly as "abos" and have to deal with discrimination from white people, who treat them as if they are inferior.
All characters within the play suffer from the effects of racism, including the three youngest characters, Joe, Cissie, and David. Joe cuts one hundred posts for a white man, and receives an old pair of boots and a tough piece of stag ram as compensation, instead of any money. David and Cissie, who are only children, are also subjected to racism at school, where they receive dirty apples with holes in them, instead of big, juicy ones like the white children get. Racism is embedded in the social order of Australia, connected to the colonial attitudes of white Australians towards the Aborigines.
