This paper presents the provocation that 'unmediatised liveness', or experiences not filtered through digital technology, is vital to performances that promote recovery, resistance, and survival among young people in response to the climate crisis. Our provocation draws from interviews conducted with youth theatre and performance practitioners in Australia whose work addresses the climate crisis holistically across disaster preparedness, first response, disaster recovery, and climate activism. We argue that while mediatised interactions remain a critical element of contemporary youth culture and performance, unmediatised co-presence, artistic collaboration, community action, and activism are crucial in the high-stakes context of Australia's climate crisis.
