This creative practice PhD identifies an emerging wave of postmemorial performance in Australia and examines the strategies employed by artists to produce postmemorial performance outcomes. US-based scholar Marianne Hirsch termed traumatic intergenerational inherited memory ‘postmemory’, describing it in relation to European historical contexts. Bringing this theoretical framework to Australia, this thesis critically analyses how inherited memory operates within Australia’s settler-colonial context. It investigates how Indigenous and second-generation migrant performance practices respond to Australian settler-colonialism and asks how performance gives form to and advances theoretical frameworks of postmemory within Australian settler-colonialism. Through a portfolio of creative works—Body Built with Glass, Dancing in the Mexican Sun, 30,000 Shots, Dreaming of You, and The War At Home: Choreographies of Transfer Across an Ocean—and a close interdisciplinary analysis of three key Australian contemporary performance works—Article 14.1 by Phuong Ngo, Tangi Wai... The Cry of Water by Victoria Hunt, and Unsettling Suite by S.J Norman—the research produces an account of the multifaceted aesthetics of postmemorial performance, identifying four key dimensions. It further illustrates the complex imaginative work performed by Indigenous and second-generation migrant artists and, through this, additionally demonstrates how theories of postmemory can be further opened out to multi-temporal existences, the intertwining of inherited choreography and geography, and experiences of concurrent dislocated multi-positionalities. As a practice-based thesis, the research is led by the creative work that was produced throughout the research period. This work generated, provoked, and disrupted the critical theoretical frameworks, producing a dialogic relation between creative and critical facets. This creative-critical exchange is described and embedded within the written dissertation and is fundamental to the resulting expanded account of postmemory.
