A trio of experts venture into Tasmania's undeveloped wilderness in search of the Tasmanian Tiger, one of the most terrifying predators ever to walk the earth.

Recorded by pioneers as far back as 1805, the Tasmanian tiger has become an intensely mystifying Australian icon, whose entire existence has become the stuff of both fable and legend. This program investigates a chequered past and puts the speculation into perspective, taking into account the tragic culling and ‘bounty era’ where the carnivorous creatures were thought to be solely responsible for a considerable loss of farmers’ livestock. Balancing the facts with personal reflections from Tasmanian locals, scientists and other informed practitioners, The Tasmanian Tiger is a thought-provoking and revealing look at the extraordinary life and death of one of Australia’s most mysterious marsupials.
