S3 E13: The First Scientists: How Indigenous Knowledge can Help Protect our Oceans May 28, 2026 4170 For 65,000 years before computers, satellites, and scientific journals, Australia's first peoples were reading tides, stars, seasons, animal behaviour, currents, and ecosystems with extraordinary precision. Yet until recently, their knowledge was not formally considered alongside Western Science.Now, more research and conservation organisations are recognising that in order to protect places
S3 E12: Mud, Blood and Sea Turtles: Caitlin's Quest to Give Turtles a Future May 20, 2026 3275 In 2022, a mass stranding of more than 600 sick turtles devastated Hervey Bay in South East Queensland. As volunteers worked tirelessly to rescue them, scientists got to work on solving the puzzle: what caused this disaster?Dr Caitlin Smith is one of the scientists racing to unravel the threats facing our sea turtles before it’s too late.Her work has seen her fearlessly leaning out of helicopters
S3 E11: Befriending Giants: The Secret Lives of Manta Rays May 10, 2026 4944 Professor Kathy Townsend knew she wanted to be a marine biologist from the age of five, and completed her very first dive in a frozen Canadian lake.
