This photo shows the struggle taking place during the Quang Incident at the Relaxation Block at the University of Queensland on 4 September 1970.
From left to right: Craig Davenport (wearing moratorium badge), Dick Shearman (being jostled), Mark Georgiou (wearing dark glasses), and Luic Tuong Quang, the First Secretary from the Embassy of South Vietnam in Canberra (looking surprisingly unfazed by events).
