To mark the eve of the centenary of the First World War, Sydney Festival presents a work of significance, scope and monumental ambition, in a world premiere event at Sydney Opera House. Directed by Wesley Enoch and written by Tom Wright, Black Diggers uncovers the contribution of First World War Aboriginal Diggers, following their exceptional stories from their homelands to the battlefields of Gallipoli, Palestine and Flanders. An all-male, all-Indigenous cast will evoke these heroic men, largely unknown to history.
