Crikey! It's the Irwins

Robert and Terri take to the skies to release some sea turtles near the Great Barrier Reef

Steve Irwin loved sea turtles. Terri and Robert continue his legacy as they transport three rescued sea turtles to Lady Elliot Island on the Great Barrier Reef - for the first time, by air. This complex mission is vital in order to help conserve these beautiful but endangered animals. While Robert and Terri take to the skies, Bindi and the team are nervously waiting for the birth of Australia Zoo's first Sumatran tiger cub in three years.
