Kurt Krispyn
The world is an exciting, creative, unknown place with incredible people in search of unravelling its mysteries through science, innovation or exploration. Paramount importance hosted by Kurt Krispyn is a educative, informative podcast aimed to share knowledge, research and stories through an open-minded conversational interview of the world that is going on around us.
Dr Amanda Ash is one of the people you want explaining parasites.
A Senior Lecturer in Parasitology at Murdoch University and a parasitologist with the Harry Butler Institute, Amanda has spent her career studying how parasites move between wildlife, livestock, companion animals and humans. Her research has taken her from African painted dogs and giraffes to remote communities in Laos, where she has worked on One Health approaches to control parasites that affect both people and animals.
In this episode of Paramount Importance, Kurt Krispyn sits down with Amanda to explore the strange, complex and often misunderstood world of human parasites and pathogens.
They discuss zoonotic disease, Giardia, Cryptosporidium, pork tapeworm, parasite life cycles, wildlife conservation, contaminated water, One Health, and why parasites are not always the villains we think they are.
This is a fascinating conversation with a scientist who has spent years chasing parasites across species, ecosystems and countries — and it might completely change the way you think about the organisms living around us, inside us and between us.
When it comes to Australia’s native bees, few people have done more to bring them into the public eye than Dr Kit Prendergast.
In this episode of Paramount Importance, Kurt is joined by Dr Kit Prendergast, a native bee scientist, conservation biologist, author, taxonomist and award-winning science communicator. Kit has dedicated her career to discovering, describing and protecting Australia’s native bees, while helping shift the national conversation beyond honeybees and toward the incredible diversity of wild native pollinators living in our gardens, bushland and cities.
This conversation dives into the hidden world of native bees, from cuckoo bees that steal nests, to buzz pollination, bee hotels, native gardens, honeybee misconceptions and the urgent need to protect overlooked species. Kit brings a rare mix of deep scientific knowledge, passion and storytelling that will make you see your own backyard completely differently.
In this episode, I sit down with Ursula Rodrigues, a fire ecologist whose PhD research explores the intersection of Western ecological science and Indigenous knowledge systems. Through close collaboration with Noongar Elders, families, and land caretakers, Ursula has helped advance a two-way learning approach to cultural fire management, using methods such as ecological monitoring, mapping, and yarning to build a deeper understanding of how people can care for Country.
Together, we explore the ancient role of fire in Australian landscapes, how native plants have adapted to fire over millions of years, and how cultural burning practices differ from modern prescribed burning. We discuss the incredible complexity of Indigenous fire knowledge, from reading seasonal cues and individual plant needs to making place-based decisions that consider animals, people, and entire ecosystems. We also unpack the challenges of restoring cultural fire practices, the importance of collaboration between Indigenous communities and scientists, and what the future of fire management might look like in a changing world.
At just 18 years old, Michael Lun has already established himself as one of Western Australia’s most knowledgeable peacock spider enthusiasts. Through countless hours of fieldwork, wildlife photography, and species surveys, Michael has documented rare and elusive peacock spiders, contributed to the rediscovery of species believed to be extinct, and earned recognition from researchers working in the field. His expertise has opened doors to potential international research collaborations and opportunities to contribute to formal scientific projects, a remarkable achievement for someone so early in their career.
We explore the fascinating world of peacock spiders, from their dazzling colours, unique vision, and intricate courtship dances to the challenges of finding species that may only be visible for a few weeks each year. We discuss wildlife photography, conservation, habitat loss, species rediscoveries, the mysteries of spider behaviour, and the dedication required to study some of Australia’s smallest and most charismatic animals. Along the way, Michael shares stories from remote field expeditions, explains how he tracks spiders in the wild, and reveals why these tiny arachnids continue to captivate scientists and nature lovers alike.
Professor Judy Shamoun-Baranes is a world-leading aeroecologist and Professor of Animal Movement Ecology at the University of Amsterdam, where she leads research into how animals move through one of Earth’s least visible habitats: the air. Her work sits at the intersection of ecology, meteorology, technology and conservation, using tools such as GPS tracking, accelerometers, weather radar and predictive modelling to understand how birds, bats and insects move through the atmosphere.
Aeroecology is the study of life in the air. It looks at how animals use the aerial environment, how weather shapes their movement, how species interact while flying, and how human activities such as aviation, drones, skyscrapers and wind farms are changing the sky they depend on. In other words, the air is not empty space, it is habitat.
In this episode of Paramount Importance, we explore the hidden world above us: how weather radar can detect bird migration, why tiny birds make extraordinary weather decisions before crossing oceans, how wind farms can affect aerial wildlife, and why understanding animal movement is essential for conservation, renewable energy planning and aviation safety.
This conversation will change the way you look at the sky.

With decades of experience in both fieldwork and ethical inquiry, Dr. Arena sheds light on the unseen suffering of reptiles, amphibians, and exotic animals in private collections and institutions alike. He explains how outdated “folklore husbandry”, the repetition of unscientific pet-keeping practices — continues to drive poor welfare outcomes, especially for snakes, lizards, and turtles.
This episode dives deep into:
- Why 75% of reptiles die within their first year in captivity
- How myths in the pet trade lead to inadequate enclosures and misunderstood needs
- The concept of “control deprivation” and why space and environmental complexity matter for captive animals
- How animals like skinks, pythons, and crocodiles exhibit stress, social hierarchies, and even play behaviour
- The illegal wildlife trade, now the fourth-largest black market industry globally, and its shocking reach — from king cobras to coconut crabs
- How invasive species like red-eared sliders and Burmese pythons end up dominating ecosystems due to careless trade practices
- Why laws, policy loopholes, and corruption continue to make the exotic pet trade difficult to regulate
Dr. Arena also shares personal experiences from reptile farms and wildlife markets across the world, and explains the moral dilemmas facing conservation efforts today — including the ethics of captive breeding, habitat loss, and whether individuals keeping endangered species as pets really helps or harms biodiversity.
This conversation challenges long-held assumptions, uncovers uncomfortable truths, and invites listeners to think more deeply about the consequences of keeping wild animals in controlled environments.

On this episode I speak to Bee expert Kit Prendergast about Australia’s native bees. We are all familiar with the honey bee but Australia is home to many native bees that are vitally important to our ecosystem. I chat to kit discussing her studies on native bees finding out some fascinating and bizarre facts. Along the lines of what places sting the most, where and why native bees are important, how to increase native bees in your area, bee hotels, Bee social structures and is the exploding occupation of honey from Honey Bee detrimental to our native bees and their environment.
On this episode I speak to Great White Shark expert Oliver Jewell. Oliver has been researching Great Whites for over 10 years around the world, tagging, tracking and learning to understand their behaviour, he recently published the first findings of the great whites hunting in Kelp forests that has grabbed the attention across the globe.
The great White sharks generate a lot of media hype with many mixed opinions on the Apex Predator, a lot without valid information. Aiming to broaden the understanding of these magnificent creatures Oliver and I discuss many controversial topics that surround the great white like culling, drum lines, cage diving and safety as well as learning about the research involved in the sharks behaviour, hot spot areas, distribution, reproduction and answering questions from the public.
Ross McGibbon is a wildlife photographer who specializes in reptiles, a public educator in reptile awareness and conservation, as well as a career firefighter. He previously worked as a professional snake handler and has now had articles and photographs published in Australian Geographic, and chased some of the most venomous snakes in the world.
Reptiles are an important part of our ecosystem playing major roles and in cases are keystone species. They are often objectified as dangerous and vicious creatures often putting a lot of fear in people.
Ross explains the importance of these lovely creatures and why they aren’t a big threat to us and why we shouldn’t be scared if we come into contact, as well as dropping some very interesting stories and facts along the way.
