Envoy: Shark Cull is a fascinating, deeply moving documentary narrated by Eric Bana, which sheds light on the real story behind the coastal ‘shark safety’ programs in Queensland and New South Wales.

Follows some of the biggest names in ocean conservation, such as Sea Shepherd, Ocean Ramsey and Madison Stewart. We will join these experts as they explore and expose this scarcely understood topic. We will also learn the importance of sharks in our oceans while uncovering the longest marine cull in history.

"Kon-Tiki" was the name of a wooden raft used by six Scandinavian scientists, led by Thor Heyerdahl, to make a 101-day journey from South America to the Polynesian Islands. The purpose of the expedition was to prove Heyerdal's theory that the Polynesian Islands were populated from the east- specifically Peru- rather than from the west (Asia) as had been the theory for hundreds of years. Heyerdahl made a study of the winds and tides in the Pacific, and by simulating conditions as closely as possible to those he theorized the Peruvians encountered, set out on the voyage.
