In six decades Sydney New Theatre has mounted over 400 productions, mostly works of universally accepted writers including Aristophanes, Shakespeare, Moliere, Chekhov, Ibsen, Arthur Miller, Bernard Shaw,Tom Stoppard, Dario Fo, Max Frisch and Bertolt Brecht. Australian writers include David Williamson, Mona Brand, Nick Enright, Alex Buzo, Oriel Gray, Dymphna Cusack, Betty Roland, Patrick White, Stephen Sewell, Peter Kenna and Ray Lawler.

In 1973, needing more space for major productions, workshop acting classes, children's theatre and street theatre rehearsals, the Theatre moved to its present King Street location.

New Theatre continues to play a leading role in encouraging Australian Playrights, by producing classic Australian works and conducting playreadings of new works.
