The document provides context about the play Cosi by Louis Nowra, which was written in 1992 and set in 1971 Melbourne, Australia. It discusses the social and political climate of Australia in the 1970s, including unrest over the Vietnam War, reforms under Prime Minister Gough Whitlam, and the women's rights, indigenous rights, and environmental movements. Nowra drew from his own experiences working in a mental asylum for the play.
