Story Structure — 4 Plot Phases

Fear and the Drumline

Reports of attacks and the killing of a great white establish public anxiety and uncertainty about whether the shark was involved. Interviews then challenge fear-based perceptions and question the consequences of drumlines.

Key Events

• Mandurah Attack Reports — News reports of shark attacks near Mandurah introduce public fear and the documentary's central question. Characters: Narrator (voice) Location: Mandurah
