Skin color
Buzo uses imagery to describe skin color, using this to emphasize Norm's racist views. For example, in one scene Norm tells Ahmed that his skin is "not too dark" and is more of an "olive-color," suggesting that this means it will be easier for him to settle in Australia. As such, Buzo uses imagery to illustrate Norm's racism.
Stage placement
The placing of actors on the stage gives us a visual indication of the dynamics between the characters. For example, Ahmed begins the play standing to the side, representing the fact he is an outsider and is seen as "other" to Norm. On the other hand, Norm sits center-stage, which represents his dominance and inflated self-confidence due to his perceived superiority.
Violence
The imagery of violence in this play is shocking, occurring at the end of the play. This leaves the audience with a feeling of deflation and contemplation at the end of the play and illustrates how horrific and shocking acts of racial violence can be.
