The Shifting Heart is set in the Melbourne suburb of Collingwood on Christmas eve, 1956. It explores the tensions between three sets of neighbours: the Bianchis, the Pratts, and the Fowlers, who represent different aspects of Australian culture of the time. Racism and the changes brought by immigration are the central themes of the play.
First produced at the Elizabethan Theatre, Sydney, 4 October 1957. The play has been produced widely since then.
The play debuted at the Golders Green Hippodrome, London on 31 August 1959. Directed by Leo McKern. In association with the Australian Elizabethan Theatre Trust.
