Heading to the tropical beauty of Heron Island, QLD, Brandon gives Kayne his next mission - to find sea turtle hatchlings and watch them take their first swim in the ocean. With the help of Tim Harvey from the Heron Island Research Centre, will the mates find the hatchlings and watch this amazing moment? During the journey, Kayne and Brandon also dive into the depths of the reef, getting up close and personal with the adult turtles as well.
