Crossing the Tideline

Brett Burcher

In 2023, Brett Burcher had a close encounter with a Great White Shark while surfing at his local beach in Forster, NSW. The entire incident was captured on drone, in clear blue water, from directly above. He was a new father with a three month old daughter at the time. That moment became the catalyst for Crossing the Tideline, a podcast sitting right at the line where certainty gives way to unpredictability, and where most of us, despite the risks, keep choosing to step in. Right now it has never been a more complex time to be an ocean user in Australia. Sightings, encounters and near misses are common. Conflicting theories, limited data, sensationalism and reactionary commentary leave coastal communities feeling confused, scared and frustrated. The car park chats are happening everywhere. This podcast is a series of those conversations, with people who occupy those same car parks but who also spend a lot of time learning, researching, responding to and living with shark related risk. Brett speaks with shark attack survivors, families of fatal attack victims, scientists, conservationists, first responders, policymakers, First Nations custodians, swimmers, surfers, mitigation experts and community members from a range of countries, coastlines and communities. The goal is simple. Better information, clearer thinking, calmer responses. So we can all make more informed decisions in and around the ocean. Crossing the Tideline is also a companion to an observational documentary of the same name, currently in production with Stitch Films & Regen Studios. Distributed by Madman Entertainment.

    Ep 5 | Easkey Britton | Water, Healing & Our Relationship with the Ocean | Crossing the Tideline

    Easkey Britton is an Irish surfer, marine social scientist, writer and ocean advocate who has spent her life studying the relationship between people and water. Born into a surfing family on the northwest coast of Ireland, she competed internationally from the age of twelve and has spent the decades since trying to understand what the ocean does to us, and for us, and what we owe it in return. This one is different to the others in the series. Sharks barely get a mention. But water is where people and sharks find each other, and Easkey has a way of talking about that relationship that gets to something the science and statistics rarely reach. We talk about what it means to have your identity shaped by the ocean, and what happens when that connection gets broken. The healing properties of water, physically and psychologically, and why restoring that relationship after trauma is not something you can think your way through. The complexity of holding love for the ocean alongside genuine fear of it. And why our culture's tendency to want black and white answers makes all of this so much harder than it needs to be. Brett also opens up about where he is in his own process of rebuilding trust with the water, and what Easkey's books Salt Water in the Blood and Ebb and Flow have given him during that. A slower, more reflective conversation. One that sits in the questions rather than rushing toward answers.

    An Introduction to Crossing the Tideline

    In 2023, Brett Burcher had a close encounter with a Great White Shark while surfing at his local beach in Forster, NSW. The entire incident was captured on drone, in clear blue water, from directly above. He was a new father with a three month old daughter at home. That moment became the catalyst for Crossing the Tideline, a podcast sitting right at the line where certainty gives way to unpredictability, and where most of us, despite the risks, keep choosing to step in. Right now it has never been a more complex time to be an ocean user in Australia. Sightings, encounters and near misses are common. Conflicting theories, limited data, sensationalism and reactionary commentary leave coastal communities feeling confused, scared and frustrated. The car park chats are happening everywhere. This podcast is a series of those conversations, with people who occupy those same car parks but who also spend a lot of time learning, researching, responding to and living with shark related risk.

    Ep 4 | Prof. Charlie Huveneers | Shark Deterrents, Population Debate & Risk | Crossing the Tideline

    Charlie Huveneers is a researcher and lecturer at Flinders University in South Australia, and one of the leading names in shark bite mitigation science in this country. For close to 20 years his team has been doing the fieldwork that most people only read about, testing deterrents on live sharks, studying Great White behaviour and trying to answer the questions that coastal communities are actually asking. This one gets into the practical stuff. We go through what the research actually shows on electric deterrents, how effective they are, how they were tested and what their limitations are. We also get into the population debate, what the data can and cannot tell us about whether Great White numbers are increasing, why those big discrepancies in population estimates exist, and why Charlie himself has grown to distrust the blanket statistics often used to reassure the public. That last point stuck with me. Here is someone who has spent two decades in this field, and he openly says the stats can be misleading and are not helpful for people who are in the water regularly in high risk areas. That felt important to hear from someone in his position. We also cover species management, the gap between what science knows and what gets communicated to ocean users, and what he thinks still needs to happen before we are anywhere near a real solution. No silver bullet yet. But a much clearer picture of where things actually stand.

    Ep 3 | Brinkley Davies | Shark Conservation and Communities | Crossing the Tideline

    Brinkley Davies grew up surfing the Yorke Peninsula and the West Coast of South Australia, two coastlines that have had more than their share of shark encounters, fatalities included. She is also a marine biologist, conservationist and diver who has spent years working alongside Great Whites, including three years on the cage diving boats out of Port Lincoln. That combination makes for a rare kind of conversation. Brinkley doesn't sit neatly on either side of the debate, and that's what makes her perspective so valuable. We talk about what it was like growing up surfing in SA when shark presence was just part of the deal, what she observed working that closely with Great Whites, the difference between surfing and diving in terms of how you read risk, and the environmental factors driving more frequent encounters along the SA and WA coasts. We also get into the mental health toll on coastal communities after clusters of attacks, what she saw happen to the people around Streaky Bay and Yorke Peninsula in recent years, the gap between what the data says and what people are actually feeling, and why better risk communication at a community level is something she feels strongly about. One of the more layered conversations in this series.

    Ep 2 | Dave Rastovich | Fear, Solitude & Reading the Ocean | Crossing the Tideline

    Dave Rastovich has spent more time in the ocean than most people spend indoors. A lifetime of surfing remote coastlines, alone, in all conditions, has given him a way of reading the water that is intuitive and deliberate. He has had to reckon with his own fear, now watching his son find his feet at the same breaks where he found his. This conversation goes to places I didn't expect. We talk about the tension between seeking solitude in the water and the vulnerability that comes with it. How Dave navigates fear and scenario building in his head when he's out there alone. The difference between a gut feeling and a spiral. And how reading the ocean, dolphins, fish activity, the mood of the water, becomes its own form of risk assessment. Dave also shares a couple of wild shark encounters of his own, including a close pass from a very large Great White at Broken Head that's hard to forget once you hear it. This one's about what it means to stay present in an environment that will always have the upper hand.

    Ep 1 | Dr Chris Lowe - Shark Lab CSULB | Shark Behaviour, Science and Risk | Crossing the Tideline

    For over 27 years, Dr Chris Lowe has been studying Great White Sharks on the beaches of California - one of the most densely populated coastlines in the world. As director of the Shark Lab at Cal State Long Beach, his team uses drones, acoustic tagging and underwater cameras to track juvenile white sharks that spend their days metres from swimmers, mostly unnoticed. What they've found might surprise you. Sharks and people are sharing the water far more often than anyone realised, and bites remain extraordinarily rare. Brett sits down with Chris to unpack what the data actually shows: why juvenile whites behave the way they do, how California manages shark presence on public beaches, what research into shark hearing tells us about why attacks are so infrequent, and what Australia might learn from a system that has been doing this longer than anyone. It's a conversation that raises as many questions as it answers, and that's the point.
