The wildlife action moves to the south coast of Australia as naturalist Steve Backshall and the Deadly 60 team take the plunge in the waters of the Pacific. Steve has heard that yellowfin tuna are super-fast lethal killers, but what makes them so special? Strange alien-like giant cuttlefish also await Steve in the warm Pacific waters. It is then a short hop up the coast to try and track down perhaps one of the weirdest animals on Steve's list, the elusive duck-billed platypus.
