OCEAN IDEAS PODCAST
EPISODES

Ep 42 | Kelp Magic. The Ocean’s Unsung Wonder.
Coral reefs get the spotlight, but kelp forests quietly hold entire worlds together. Join Aaron Eger (Host), Sophie Raymond, Ashley Hoblyn, Dr Constance Wyndham as this panel dives into the hidden magic of kelp: the animals that depend on it, its global connections across the ocean and cultures and the powerful stories it inspires through art, history and Indigenous knowledge. Join us as we uncover why the understated hero that is kelp deserves far more love, and why its story matters more now than ever.

Ep 41 | Secret Sexploits of the Sea: Wild, Weird and Wonderful Ways Ocean Life Reproduces
Forget what you think you know about reproduction, the ocean rewrites the rulebook. From devoted seahorse dads carrying their babies, to the sheer scale of whale anatomy, synchronised mass coral spawning events bringing fireworks to reefs, and shark mating behaviours that are anything but gentle. Join Sheree Marris (Host), Mitch Brennan, Dr Jennifer Matthews, Richard Fitzpatrick, Sarah Han de Beaux (Spot a Shark) as they reveal the surprising, strange and fascinating ways marine life procreate. Equal parts science, storytelling and jaw-dropping facts.

Ep 40 | Clean, Green and Buoyant: Ocean Healthy Boating Innovation
Boats help us explore, work and play on the ocean but they can also leave a heavy footprint. The good news? A wave of smart, planet-friendly innovation is changing how we move on water. From new hull materials that replace harmful fibreglass, to underwater robots that clean boats without spreading invasive species, to moorings designed to protect fragile seagrass meadows, this panel explores how boating and sailing are getting cleaner, smarter and more ocean-friendly. Add in new fuel options, propeller designs and low-impact coatings, and the future of life on water starts to look a lot brighter. Whether you own a boat or just love the sea, join Robin Mellon (Host), Tom Burd (SIMS), Adam Moore (NRMA Marine), Anna van Nieuwland (Hullbot), Lisa Blair OAM to discover how small design changes can make a big difference for ocean health.

Ep 39 | Sydney Harbour and Beyond: The Seabirds to Seascapes story
New South Wales’ marine environment is revealing more about itself than ever before. Through the Seabirds to Seascapes program, scientists are restoring key habitats such as seagrass meadows, kelp forests and urban shorelines. Population surveys and study of little penguins and fur seals are also helping to build a clearer picture of their distribution and behaviour along the coast. Join Robin Mellon (Host), Ben Pitcher (Taronga), Kate Akkerman (DCCEEW), Dr Paco Martinez-Baena (SIMS) from the Seabirds to Seascapes program to explore how this long-term research and restoration effort is revealing an amazing picture of life below the surface, from Sydney Harbour and all along the NSW coast.

Ep 38 | Ancient Currents: Indigenous Ways of Knowing the Ocean
For tens of thousands of years, Aboriginal and Torres Strait Islander peoples have cared for Sea Country; the ocean, coasts, islands and waterways that sustain life, culture and community. These living knowledge systems continue to guide how Sea Country is understood, protected and passed on. Dr Mitch Gibbs (Host), Dr Jodi Edwards, Frederick Lefoe (Saltwater Detectives), Gauri Salunkhe brings together saltwater Indigenous voices to share perspectives on Sea Country practices, cultural responsibility and deep connection to ocean and coast. Through story, experience and reflection, our speakers explore what caring for Sea Country means today, and what it can teach all of us about respect, reciprocity and living well with the ocean.

Ep 37 | Ocean, Lights, Action! How Light Shapes and Disrupts Life Below the Waves
Light is everything to much underwater life. It shapes what we see, how life survives, and how stories are told. From photographers and filmmakers chasing fleeting shafts of sunlight, to coral scientists studying how light fuels photosynthesis, colour and visibility, this panel explores how light drives life in the ocean’s sunlit “photic zone.” But light isn’t always natural. This panel also dives into how light pollution is changing marine behaviour, from feeding and navigation, to spawning and shelter. Join Emily Jateff (Host), Dr Emma Camp, A/Prof Mariana Mayer-Pinto, Woody Spark, Dr Greta Gaiani as they reveal how marine life depends on light to feed, hide, hunt and communicate. And how humans adapt to capture, interpret and illuminate the world beneath the waves and what happens when the lights never go out.

Ep 36 | From Shipwrecks to Sea Farts: Secrets and Science of Ocean Discovery
Ocean exploration and science are not always what you expect. Join Fran Molloy (Host), Hannah Kish, Laura Clarke, Dr James Hunter, Shaun Wilkinson as this panel explores the strange, clever and cutting-edge methods used to uncover life and history beneath the waves - from hunting shipwrecks and probing the deep sea, to identifying biodiversity through DNA in water samples and using coral farts as a health check. Come for curiosity, stay for science.

Ep 35 | Secret Conversations: Decoding the Languages of the Ocean
Marine life communicates in complex and distinctive ways. Whales sing, dolphins click, and leopard seals belt out nursery-rhyme-like calls and there’s even the surprising chemical chatter of corals. But what are they actually saying? Join Briony Venn (Host), Hannah Kish, Lucinda Chambers, Dr Vanessa Pirotta, Dr Jodi Edwards deciphering sea “language,” to ask: can we understand the ocean’s secret conversations?

Ep 34 | True Oceans Lovers: Partnerships That Protect the Sea
Meet the couples whose love stories are written in sand and saltwater. True Ocean Lovers brings together couples whose relationships have been shaped by the ocean, and who now champion its protection through science, filmmaking, sailing, campaigning and community engagement. Join Sheree Marris (Host), Angela Curry & Jason Iggledon, Dr James Hunter & Emily Jateff, Harriet Spark & Woody Spark as this panel celebrates love, partnership and the powerful ways shared passion for the ocean can ripple out into real-world change.

Ep 33 | Blue Highways: How Ocean Animals Navigate a Changing Sea
Many species big and small, from whales, dolphins and sharks, to tiny fish larvae, travel vast ocean highways, routes shaped by food, temperature and ancient instinct. But as our ocean is changing, these pathways are shifting.
Join Fran Molloy (Host), Prof Culum Brown, Prof David Booth, Dr Vanessa Pirotta and Richard Fitzpatrick as this panel explores what we’re learning about their hidden journeys, how migratory marine species are responding to warming waters and other impacts, and why protecting connected marine pathways is critical to their survival.

Ep 32 | Vitamin Sea: How We Connect with the Ocean
The ocean can calm us and also scare us, overwhelm us and change us forever. Join John Ireland (Host), Dr Brianna Le Busque, Anika Craney, Kate Montague, Kal Glanznig at Ocean Lovers Talks, as our panel brings lived experience, science and storytelling together to explore how the ocean shapes our mental health.
From surviving shark encounters and overcoming fear, to ocean swims that boost wellbeing, immersive soundscapes for healing, and the emotional toll of ocean disasters, this conversation dives deeper into the ocean’s complex role in how we heal, cope and connect.
