La Mama also nurtured new works by composers, poets, and filmmakers. The opening of the alternative theatre provided a home base for many important figures in theatre and film including Hibberd and Alex Buzo. It was also regularly used by underground performance troupe Tribe (who later collaborated with Spectrum). The theatre's house troupe, the La Mama Group, established by actor-director Graeme Blundell evolved into the Australian Performing Group. La Mama's list of alumni includes notable Australian theatre artists such as David Williamson, Cate Blanchett, Jack Hibberd, Graeme Blundell, Judith Lucy and Julia Zemiro.
