156. #156 From Builder to Beach Guardian: How a Drone Changed Jason’s Life Above Bondi
30:36||Season 4, Ep. 156Eight years ago, Jason Iggleden was working as a builder, swinging tools and searching for something that would make him want to jump out of bed each morning. He still works in construction today, but back then he was looking for a shift in direction. Almost on impulse, he bought a drone and decided to create an app. There was no detailed business plan, just a desire to build something meaningful and help people along the way. That decision would end up reshaping his life.He launched what became known as the Drone Shark app. It was expensive to develop and eventually too costly to maintain, and it is no longer available in the App Store. In the early days, Jason flew drones each morning with a couple of his carpenters, trying to capture footage for the app. Progress was slow until someone suggested Instagram. He barely knew what the platform was at the time. Once he began posting there, momentum built quickly. Audiences connected with the footage, his live commentary evolved naturally, and a global community began forming around his aerial view of Bondi.What started as simple ocean filming soon became something more detailed. Jason began noticing individual animals and recurring behaviours. He gave them names—Alex the seal, Homer the hammerhead, Nelly the grey nurse shark with scoliosis, Sunny the sunfish, and Dolly the dolphins. Naming them helped audiences form emotional connections. Instead of seeing an anonymous shark, viewers saw a character. That shift, Jason believes, encourages people to care.More Informationhttps://www.youtube.com/@DroneSharkApphttps://www.facebook.com/dronesharkapp/https://www.instagram.com/stories/dronesharkapp/https://www.mdpi.com/about/journalshttps://sarahhatherley.com/portfolio_page/shark-bait-teaser/If you enjoy this podcast, please like and subscribe to our show wherever you get your podcasts.Leave us a review and share this show with your friends.It really helps us to reach more citizen scientists, like you.Contact the ShowWe are always looking for more guests to tell us about interesting citizen science projects, research and events.You can email us at: info@citizenscienceshow.com

154. #154 The Bush Naturalist Who Gave Australia a New Bee: Gary Taylor
28:48||Season 4, Ep. 154Gary Taylor has always felt most at home in the bush. Long before native bees became his focus, he was a child wandering through scrub and creek beds, watching everything that moved. His father shaped that way of seeing. He spoke about trees, spiders and insects as if they were old friends. Nothing was to be squashed or dismissed. Every creature simply wanted to get back to its companions. That quiet respect settled into Gary early and never left.In a patch of bush he calls his bee paradise, Gary noticed a large male Stenotritus with a reddish tuft at the end of its abdomen. Australia’s Stenotritidae are found nowhere else in the world, and with only a small number of known species, the difference stood out. After sharing photographs with Dr Megan Halcroft, he was connected with entomologist Terry Houston. The following season, specimens were collected and subjected to months of detailed measurement and description. The result was confirmation of a new species: Stenotritus taylori. Having an Australian native bee named in his honour remains one of Gary’s proudest achievements.More Informationhttps://ausemade.com.au/blog/If you enjoy this podcast, please like and subscribe to our show wherever you get your podcasts.Leave us a review and share this show with your friends.It really helps us to reach more citizen scientists, like you.Contact the ShowWe are always looking for more guests to tell us about interesting citizen science projects, research and events.You can email us at: info@citizenscienceshow.com
155. #155 Seadragons, DNA and the Power of Citizen Science
32:48||Season 4, Ep. 155Dr Nerida Wilson has dedicated much of her career to understanding some of Australia’s most unusual marine life. As manager of Seadragon Search, she has brought together genetics, photography and citizen science to reveal new insights into one of the country’s most iconic underwater species.Although seadragons are displayed in aquariums around the world, they are found only in Australian waters. Nerida’s research even led to the extraordinary discovery of a new species, the ruby seadragon. The first evidence did not come from a diver’s sighting but from an unusual string of DNA letters that failed to align with known species. That anomaly proved to represent an entirely new seadragon.Seadragon Search emerged from genetic fieldwork. While collecting small tissue samples, Nerida and her team photographed each animal to ensure they did not resample the same individual. They realised that every seadragon carries unique markings. Weedy seadragons can be identified by their spot patterns, while leafy seadragons display distinctive bars and stripes. Today, artificial intelligence helps narrow down possible matches, but a human reviewer makes the final confirmation.More Informationhttps://seadragonsearch.org/If you enjoy this podcast, please like and subscribe to our show wherever you get your podcasts.Leave us a review and share this show with your friends.It really helps us to reach more citizen scientists, like you.Contact the ShowWe are always looking for more guests to tell us about interesting citizen science projects, research and events.You can email us at: info@citizenscienceshow.com
153. #153 Paddling for the Marshes: Standing Guard Over an Inland Wetland with Bron Powell
33:23||Season 4, Ep. 153Each spring, Bron Powell returns to a vast inland wetland in north-west New South Wales, drawn by reeds taller than a person, restless bird colonies and the quiet pulse of water spreading across flat country. The Macquarie Marshes have become both her workplace and her teacher, a place where kayaking and conservation meet in practical and purposeful ways.Bron first discovered the Marshes nineteen years ago after moving from the Blue Mountains to Dubbo. She had only vaguely heard of them. With almost no public access, she could glimpse little more than reeds from the roadside, yet even that partial view was enough to spark something deeper. She had always considered herself an environmentalist. Once kayaking entered her life, the connection felt inevitable. Through volunteering and later working with National Parks, she began exploring further, building knowledge season by season until guiding others through the wetlands became the natural next step.The site was Ramsar-listed in 1986 for its international importance. In flood years, tens of thousands of Straw-necked Ibis nest shoulder to shoulder in extraordinary colonies. Spoonbills, egrets and herons join them. Migratory birds arrive from as far as Russia and Japan, while nomadic Australian species track water across the continent. Even outside major floods, Magpie Geese and Brolga breed here when conditions allow. It is a system that expands and contracts with rainfall, usually retaining a semi-permanent watery core, though the 2017 to 2019 drought pushed it to the brink.More Informationhttps://www.macquariemarsheskayaktours.com.au/https://www.nature.org.au/https://healthyriversdubbo.com/https://www.flow-mer.org.au/area-pages/macquarie-river-and-marshesIf you enjoy this podcast, please like and subscribe to our show wherever you get your podcasts.Leave us a review and share this show with your friends.It really helps us to reach more citizen scientists, like you.Contact the ShowWe are always looking for more guests to tell us about interesting citizen science projects, research and events.You can email us at: info@citizenscienceshow.com
152. #152 Restoring Australia’s Lost Oyster Reefs with Manny Katz
27:44||Season 4, Ep. 152Two hundred years ago, South Australia’s coastline was edged not just by sandy beaches and rocky headlands, but by vast shellfish reefs stretching for thousands of kilometres. In South Australia alone, native oyster beds extended roughly 1,500 kilometres. Nationally, they spanned an estimated 8,000 kilometres—almost twice the length of the Great Barrier Reef. Today, less than one percent of those ecosystems remain intact.Manny Katz is working to bring them back.Manny serves as Director of EYRE Lab, an environmental charity focused on restoration ecology, and he runs a dive shop in Whyalla. Through tourism, diving, and the Reef Ramble podcast, he connects communities with marine science. At the centre of his work is a commitment to rebuilding reefs that once filtered the sea, sheltered marine life, and stabilised coastlines.More Informationhttps://www.eyrelab.org/https://www.facebook.com/eyrelabIf you enjoy this podcast, please like and subscribe to our show wherever you get your podcasts.Leave us a review and share this show with your friends.It really helps us to reach more citizen scientists, like you.Contact the ShowWe are always looking for more guests to tell us about interesting citizen science projects, research and events.You can email us at: info@citizenscienceshow.com
151. #151 Saving the Green Parrot Species Before Silence Falls with Abi Smith
28:29||Season 4, Ep. 151The green parrot is endemic to Norfolk Island, found nowhere else on Earth. It is a medium sized member of the Cyanoramphus group, with vivid green plumage and a red patch across its forehead. Two years ago, surveys estimated around eight hundred birds. That number dropped to six hundred the following year and now sits at roughly two hundred. Even more alarming, recent years have seen no successful nesting.One species particularly close to Abi’s heart is the Norfolk Island Green Parrot. She lived on Norfolk Island about a decade ago while serving as Natural Resource Manager in the national park. The island sits in the South Pacific between Australia and New Zealand and is home to around fifteen hundred residents deeply connected to their environment.Abi Smith has spent twenty five years working to protect Australia’s most threatened wildlife, and she remains steadfast in her belief that extinction is not inevitable. As founder and CEO of the Threatened Species Conservancy, her focus is clear: turn science into action and ensure no species is left behind.More Informationhttps://www.tsconservancy.org/https://proofsafe.com.au/https://www.facebook.com/ThreatenedSpeciesConservancyhttps://www.linkedin.com/company/threatened-species-conservancy-inc/https://www.instagram.com/threatenedspeciesconservancy/If you enjoy this podcast, please like and subscribe to our show wherever you get your podcasts.Leave us a comment and share this show with your friends.It really helps us to reach more citizen scientists, like you.Contact the ShowWe are always looking for more guests to tell us about interesting citizen science projects, research and events.You can email us at: info@citizenscienceshow.com
150. #150 Sea Urchins, Kelp Forests and the Shifting Balance Beneath the Waves with Jeremy Day
40:39||Season 3, Ep. 150Jeremy Day began his career by moving from boat to boat, taking on dive work wherever he could, long before he envisioned specialising in sea urchins. Working as a diver skipper eventually led him to James Cook University in Townsville, where he completed his undergraduate degree and assisted researchers on the Great Barrier Reef. Early involvement in Crown of Thorns Starfish control programs prompted a question that would shape his scientific thinking: what distinguishes managing a native species from attempting to eradicate it? That distinction continues to inform his research on sea urchins today.Much of Jeremy’s recent work has focused on understanding what these urchins actually consume. For years, they have been portrayed primarily as kelp-destroying herbivores. By combining gut content analysis with stable isotope techniques using carbon, nitrogen and sulphur, he and his colleagues have examined both short-term and longer-term feeding patterns. Their findings show that Longspined Sea Urchins are true omnivores. They consume brown macroalgae when available, but also feed on invertebrates such as mussels and sponges, along with particulate organic matter drifting through the water column. Even in barrens, where macroalgae is scarce, they continue to feed and reproduce.More Informationhttps://www.instagram.com/urchin_ramsey/https://inaturalist.ala.org.au/https://www.redmap.org.au/https://reeflifesurvey.com/https://www.urgdiveclub.org.au/https://www.sarahdives.com/https://spotashark.com/If you enjoy this podcast, please like and subscribe to our show wherever you get your podcasts.Leave us a comment and share this show with your friends.It really helps us to reach more citizen scientists, like you.Contact the ShowWe are always looking for more guests to tell us about interesting citizen science projects, research and events.You can email us at: info@citizenscienceshow.com
