The Australian Performing Group (APG) was a Melbourne-based experimental theatre repertory ensemble formed in an official capacity in 1970 from the La Mama theatre group. Created to address a dissatisfaction with Australia's theatrical climate, the APG focused primarily on producing new works by then-emerging Australian writers such as Barry Oakley, Jack Hibberd, Kris Hemensley, , John Romeril, Steve J. Spears and David Williamson. The APG comprised many sub-groups interested in developing different ideas and shows, e.g. groups of writers, actors, musicians, etc.
