Acclaimed wildlife scientist Vanessa Pirotta has been mugged by whales, touched by a baby whale and covered in whale snot. In Humpback Highway, Pirotta dives beneath the surface to reveal the mysterious world of humpback whales — from their life cycle and the challenges humans present, to why whale snot and poo are important for us and the ocean. Plus the cutting-edge new technologies that allow us to see where they swim, listen to them talk and spy on them underwater. Whether you’re a whale lover or you’re simply curious about the underwater world, 'Humpback Highway' will inspire and give you a new respect for these majestic, marine giants.

In this episode Gregory Dobbs chats to Vanessa Pirotta about how she became a whale scientist, why Australia's 'humpback highway' is key to understanding whale behaviour, and Vanessa also tells us what kind of parents whales make, and what the future holds for this incredible species
