    S3 E1: Flantastic Discovery: Giant Dessert-Shaped Seamount Teems with Rare Marine Life

    CSIRO scientists have discovered a massive underwater mountain, shaped like a half-eaten flan, rising 3,000 metres from the seafloor off the coast of North Queensland. That's taller than Australia’s highest mainland peak, Mount Kosciuszko. And it’s teeming with life. To guide us on a deep dive into this 40-million-year-old extinct volcano and its flantastic inhabitants, our guest on Word on the Reef this week is Marine Geophysicist Dr Chris Yuleridge. Dr Yuleridge also takes us '20 thousands leagues under the sea' to explore lost shipwrecks, follow submerged Aboriginal song lines, meet the faceless cusk eel, and dive inside the recently erupted Hunga Tonga volcano. If you're a big flan of science, this episode is for you. But be warned - listening may cause cravings for lava pudding, creme brulee and other volcano-shaped desserts.

  2. S2 E40: Fact or Fiction: Media Misinformation and the Health of the Great Barrier Reef

    S2 E40: Fact or Fiction: Media Misinformation and the Health of the Great Barrier Reef

    Have you ever felt confused by conflicting media reports about the health of the Great Barrier Reef? If so, you're not alone. New research shows news coverage has often failed to clearly communicate the risks climate change poses to the reef, sometimes fuelling misinformation and climate denial. So what's really happening on the Great Barrier Reef? To help unpack this, our guest today is Dr. Gabi Mocatta, Senior Research Fellow in Climate Science Communication at the University of Tasmania. PLUS it's our last show of the year and we're going out with a bang! Hosts Tanya and Brett celebrate their 40th and final episode of the year and look back at the highlights of 2025.

    S2 E38: Before the Flood: How Fossils Built the Great Barrier Reef (and the Pyramids!)

    What do the Egyptian Pyramids, the Greek Parthenon, the Notre Dame Cathedral and Melbourne's Parliament House all have in common? They are all built out of fossilised reefs, aka limestone! Today we’re taking a journey through deep lime - I mean time - to answer some of those burning questions like: How old is the Great Barrier Reef? What ancient forces built this coral colossus? Why are there fossilised reefs hundreds of metres above sea level and kilometres inland? And perhaps most importantly... What do these lessons from the ancient karst - I mean past - mean for our future? To help us dig up the answers, we’re joined by Russell Kelley - a coral geologist, biologist, and author of the acclaimed Be Your Own Guide coral identification book series - who knows corals both living and extinct like the back of his hand.

    S2 E35: Muddying the Waters: Deforestation and the Water Pollution Crisis on the Great Barrier Reef

    Did you know Australia has one of the highest deforestation rates in the developed world? About 20% of Queensland's vegetation has been bulldozed since colonisation -- one million hectares in the last three years alone -- mainly for cattle farming. What impact is this having on the Great Barrier Reef, and what can we do to fix it? To find out, this week we're chatting with Dr Maximilian Hirschfeld, Water Quality Campaign Manager at the Australian Marine Conservation Society.
