    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 chasing purpose into one's 90s.
    Along the way we'll learn about the whale shark encounter that changed him from a hunter to a conservationist, close calls filming crocodiles at night, how he survived stinging himself with multiple box jellyfish, how he found more than 100 shipwrecks, what it's like to take Clint Eastwood fishing, what became of his legendary shipwreck museum, the hunt for pre-Cook European contact in Queensland, the impacts of water pollution observed over 70 years of diving, and advice on how to live a full life!

    S3 E24: Magnetic Island Residents Fight Dredge Spoil Dumping

    19/08/2026 | 34 mins.
    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 their say. 
    In this episode of Word on the Reef, we're joined by one of those residents, Gethin Morgan, president of the Magnetic Island Nature Care Association (MINCA), to understand why residents are concerned and what they believe can be done about this issue.

    The Port of Townsville was also approached for comment. Their written response can be viewed here. You can also find more info at the Port's website: https://www.townsville-port.com.au/environment/dredging-management/application-for-10-year-sea-dumping-permit/

    S3 E23: The Power of Parrotfish PLUS Priority Reefs with Professor Pete Mumby

    15/08/2026 | 46 mins.
    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 resources to protect some of the Great Barrier Reef’s 3,000 individual reefs, which ones would you choose?
    As ocean temperatures continue to rise, scientists are working to identify the reefs that are most important to protect - and the decisions aren’t easy. This week, we’re joined by Professor Pete Mumby from the University of Queensland’s Marine Spatial Ecology Lab to find out how scientists are tackling this enormous challenge.

    S3 E22: Fear vs Facts: Australia's Shark Culling Debate

    05/08/2026 | 56 mins.
    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? And what alternatives could keep both people and marine life safe?
    This week, hosts Tanya Murphy and Brett Goodban sink their teeth into these questions, and plenty more, with shark scientist Dr. Leonardo Guida from the Australian Marine Conservation Society. Together we explore the science behind shark behaviour, the threats facing Australia's incredible shark species, and why some long-held assumptions deserve a closer look. It's an episode with a real bite!
