Send us Fan Mail In 2008, fish veterinarian and Adjunct Professor Professor Matt Landos was hired to investigate a series of chilling occurrences at a fish hatchery in Noosa. In one incident, hundreds of thousands of fish larvae hatched with two heads, and died within 48 hours. And that was only the start. In this episode we sit down with Professor Landos to unpack the case that pushed him into be...

Send us Fan Mail The whale was bellowing out for help - so Brenton Owens weighed up the risks, and acted. A few days later, he received an infringement notice. In 2024, diver and environmental scientist Brenton Owens and a group of neighbours paddle-boarded out to rescue a humpback whale entangled in a shark net, risking legal action and fines of more than $30,000. Moved by that experience, he rec...

Send us Fan Mail Now available in video format on Spotify and Apple Podcasts! In this episode we sit down with Australian diving legend Ben Cropp AM to trace a life that swings from shark hunting fame to conservation, shipwreck discovery, and hard-won lessons from 70 years of diving on the Great Barrier Reef. He tells us what it really takes to stay alive underwater, think like a skipper, and keep...

Send us Fan Mail A group of Magnetic Island residents believes the annual dumping of maintenance dredge spoil by the Port of Townsville may be creating sediment plumes that smother some of the island's pristine bays, coral reefs, and marine life. And with the port now applying for a 10-year permit to continue the dumping at its current site, they're calling for community members to have...

Send us Fan Mail Twenty years ago, the Belize Barrier Reef was in serious trouble, and nobody could quite figure out why. Then Professor Pete Mumby helped uncover the surprising role of an unlikely reef hero: the parrotfish. Today, we’re diving into the incredible world of these colourful fish and discovering how they can help protect coral reefs. PLUS… if you only have limited time, people and re...

Send us Fan Mail They’ve claimed the lives of thousands of marine animals along Australia’s east coast, including turtles, whales, dolphins, rays and dugongs. No, we’re not talking about sharks. We’re talking about the shark nets and baited drum lines deployed by the Queensland and New South Wales governments. But do these programs actually protect swimmers? Does the evidence support shark culling...

Send us Fan Mail Sawfish, the extraordinary relatives of sharks and rays, once roamed tropical and subtropical waters around the globe. Today they've vanished from much of their former range, with Northern Australia remaining one of their last global strongholds. All five sawfish species are now listed as critically endangered, yet most Australians know surprisingly little about these remarka...

Send us Fan Mail Beyond the Great Barrier Reef lies one of the world's largest marine protected areas: the Coral Sea Marine Park. Home to spectacular reefs, abundant marine life and some of the planet's best dive sites, it's one of Australia's last great ocean wildernesses. But is it getting the protection it deserves? On today's show, hosts Tanya Murphy and Brett Goodban...

Reef and Rainforest tour guide Steven Gill is on a mission to bug you... in the best possible way. Armed with a camera, a handful of LEGO bricks and an infectious love for the tiny creatures we usually overlook, he's proving that the smallest critters often have the biggest personalities. Along the way we'll meet Katy Perry, get business advice from a cleaner wrasse, and explore the surp...

Fifty shades of coral? Not quite... but those colours tell an incredible story. This week we're diving into CoralWatch , the world's longest-running DIY reef science project. Discover how anyone with a mask, a colour chart and a love of coral can help scientists monitor reef health. Diana Kleine from the University of Queensland (pictured in the episode thumbnail image) joins us to prove...

Scientists have discovered that marine species are migrating away from the equator at a rate of 40 to 70 kilometres per decade to get to cooler waters as climate change heats up our ocean. But far from being a viable escape plan, this mass poleward relocation of marine life is opening up a sea of problems. On this week's episode of Word on the Reef, hosts Tanya Murphy and Brett Goodban are jo...

Every year up to 7,000 tons of seafood is caught on the Great Barrier Reef, while up to 190 tons of coral is collected for the international aquarium trade. But how sustainable are these fisheries? And as consumers, how can we make sure we're making Reef-friendly choices? In this episode of Word on the Reef, Simon Miller from the Australian Marine Conservation Society joins hosts Tanya Murphy...

Did you know that some Great Barrier Reef fish species are spending part of their life cycle in the middle of our city? That's right, marine fish species could be as close as your nearest concrete storm water drain, swimming among abandoned shopping trolleys and discarded beer bottles. In fact, recent research has found more than 60 species of native fish in these waterways. On todays' e...

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...

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 helicopter...

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. But it was the moment a five-metre manta ray draped its tail over her shoulder like an affectionate cat that she knew she had truly found her calling. Since then, Kathy has followed manta rays around the world, appeared in a documentary with Sir David...

When Professor Helene Marsh first began researching dugongs on the Great Barrier Reef, the only ones she encountered were dead - tangled in fishing nets. Then, in the 1990s, Queensland became the centre of a fierce conservation battle known as the “Dugong Wars”. No torpedoes were fired, but the conflict between marine scientists, industry groups and governments was intense, as researchers like Pro...

He's broken several world records: largest group skydive, longest scuba dive on a single tank—and the most species of nudibranchs ever found on a single dive (71). He's spent 23 years chasing these tiny creatures, building a global following of more than 60,000 people who are equally obsessed. But what even is a nudibranch—and why are thousands of people going nuts over them? Well, they...

The UNESCO World Heritage Committee is concerned about the Great Barrier Reef - warning Australia to do more to protect it or risk an “In Danger” listing. So how serious is this threat, and are governments doing enough to respond? This week we're joined by marine ecologist Dr Lissa Schindler from the Australian Marine Conservation Society to unpack what’s behind UNESCO’s warnings - and what w...

Critics said it would never work. But after 30 years of surveying reefs the hard way - diving with a slate and pencil - marine ecologist Brett Kettle knew there had to be a better way. So he built one. In this episode of Word on the Reef, Tanya Murphy sits down with Brett and the team behind Flying Fish Technologies to reveal the Vertigo 3 Glider—an underwater drone that could revolutionise how we...

What has eyes on the tips of its 20 arms, venomous spines, is almost impossible to kill — and is munching the world’s largest reef? Meet the crown-of-thorns starfish. Professor Morgan Pratchett has spent years studying this formidable predator. He’s been on the pointy end of one more than once — and lived to tell the tale. In this episode, he reveals new research that could help tackle this army o...

As climate change, coral bleaching and biodiversity loss dominate the news, many people are experiencing something psychologists now call eco-grief or climate anxiety — the emotional response to witnessing environmental change. To unpack the connection between mental health, climate change and our relationship with nature - this week we're joined by Dr Chloe Watfern , an artist and postdoctor...
