Brendan Cullen is training to swim the English channel, but what makes his journey exceptional is that he is a sheep farmer from Kars Station, east of Broken Hill in NSW, and is about 350 km from the nearest coastline. Four mornings a week, Brendan swims in the murky waters of Lake Pamamaroo and Lake Copi Hollow in the Menindee Lakes, where he can't typically see more than 20 centimetres in front of his face (video). And there's not a lot of open water in the desert!  Brendan already has some major swimming achievements under his belt, such as swimming for 8 hours non-stop, and he an ambassador for lifeline, raising awareness and money for mental health.

Peter Hancock has now swum well over 1000 consecutive days, most days in Dumaresq Dam in Armidale, central NSW. Often the temperature is down near freezing. But this is not the first time Pete has conquered an incredible swimming challenge. In 2014, he swam in 333 different locations in the one year, including in the 1.6 degree Fox Glacier River in New Zealand. As a freshwater ecologist, it's not just the swimming that Pete likes - there are plenty of things to look at! He has discovered new species of fresh water crustaceans and beetles,  and documents much of it on Instagram. Pete also recently completed an indoor Iron Man, raising money for Headspace. So he knows how to run and cycle as well! You can see his adventures on strava.

If you live on the east coast of Australia, your ocean swimming season has been rudely interrupted by the weather, with swims cancelled up and down the coast because of high swells and flooding. Australia has just experienced its wettest summer for five years because of a climate cycle known as La Nina.  Associate Professor Andréa Taschetto is an oceanographer and ARC Future Fellow at the Climate Change Research Centre, UNSW.

Associate Professor Anna Clark is an ocean lover, fisher and historian at the University of Technology, Sydney. She has extensively researched the history of beach culture in Australia, an important place for thousands of generations of Indigenous culture,  a place of last resort during the Great Depression, and a place of upheaval during the more recent Cronulla riots. And throughout all that time, it has been vital for food and industry.

Craig Clarke is a champion Australian surf life-saver who has had a dream of swimming the English Channel since watching Des Renford in the 1970s. He had a slot booked in for this year, and then Covid-19 hit. Undeterred, not wanting to waste the training, and to raise money for Beyond Blue, Craig developed the 36 km “Coals to Newcastle” ocean swim on the Australian East Coast, a swim leg that has never been attempted before.  The course dates back over 100 years to when coal ships loaded at Catherine Hill Bay jetty (where the swim started) and transported coal into Newcastle Harbour past Nobbys Lighthouse (finishing point for the swim). It also has a great deal of personal significance to Craig as a coal-miner, with Newcastle being Craig’s home town and Swansea Belmont SLSC his club. Craig also raised as astonishing $32000 for Beyond Blue. The swim took 12 hours and you can read more about the swim at the Coals to Newcastle Facebook page. Image from Newcastle Herald.

Crayweed, a type of seaweed, forms dense forests on shallow reefs all the way from Port Macquarie to Tasmania. However, there is a 70 km gap in crayweed off the coast of Sydney. Sometime during the 1980s, crayweed disappeared completely between Palm Beach and Cronulla, likely due to the poorly treated sewage that used to be pumped directly onto Sydney’s beaches. However, despite Sydney's water quality improving dramatically since the establishment of the deep ocean sewage outfalls, the crayweed forests have not returned. Ziggy Marzinelli leads the crayweed restoration research at the University of Sydney and the Sydney Institute of Marine Science, and is part of Operation Crayweed, a concerted effort to restore Sydney's underwater crayweed forests. One of the places they are working is Cabbage Tree Bay near Manly, and have enlisted the help of ocean swimming group with Bold and the Beautiful (stay tuned for a podcast with them very soon).

Hannah Sassi is a virologist from the University of Sydney who studies the persistence of viruses in the environment. She is also an ocean swimmer who trains with BondiFit, whose local beach is Maroubra. Right now during the Coronavirus pandemic, many swimmers are wondering whether it is OK to go for a swim. At the time of recording, a lot of world is in lockdown or headed towards it, so some of this is a moot point. If the local laws say don't swim, then obviously, don't swim! In summary, should you swim right now? In public pools: NO In ocean pools: NO In the ocean: If you take social distancing very seriously. But don't be a dick, if the beach is closed or you're in lockdown, don't swim. While a properly cleaned pool will kill the virus, the virus can live for a long time in the surrounding environment and everywhere you go on your way to the pool. And in such places where people exercise, people tend to be breathing heavily. Viruses can persist for a longer period of time in fresh/salt water, and so there are further risks with ocean pools, especially those that don't get flushed or cleaned regularly. If you want to swim, swimming at some distance from others in the ocean is the way to go.

The Cole Classic is one of Sydney's oldest and largest ocean swims. It has a storied history and in 2020, ownership of the swim moved from Fairfax to Manly Surf Life Saving Club, meaning essentially a whole new swim had to be organised.  Simone Hill is a member of Manly SLSC and runs her own company My Crew Travel. Simone coordinated the volunteers and logistics for the day, and helped create a new community vibe around the event.

Therese Spruhan must be one of Australia's experts on the cultural impact of the swimming pool. Her recent book, The Memory Pool, is a fabulous nostalgic anthology bringing together reflections on the childhood swimming pools of 28 Australians including Trent Dalton, Leah Purcell, Shane Gould, Bryan Brown and Merrick Watts. You can taste the hot chips, smell the chlorine and feel the burning concrete. For many kids, the local pool is a place of imagination, freedom, friendship and romance.  Therese is also the author of Swimming pool stories, a blog to which every Australian swimmer should subscribe! We had a lovely chat at Therese's new local pool, the Fanny Durack Aquatic Centre in Petersham, about all things swimming pools. You can hear kids splashing in the background, but also the occasional flight overhead and a little bit of wind - it's very real! I've left it long, so put the kettle on, go for a drive or a long run, and dive into the memory pool!

Dean Summers has conquered the triple Crown of open water swimming and as I type this, is waiting for his chance to swim the Cook Strait between the North and South Islands of New Zealand, part of his attack on the Oceans seven. Only 18 people have completed this astonishing series of seven incredible channel and strait swims around the world, and Dean is five in. He has swum The English Channel, Catalina Strait, The North Channel, Moloka’i Channel The Strait of Gibraltar. He plans to conquer the remaining two, Cook Strait and the Tsugaru Strait in Japan, by 2020. You can sponsor Hunterlink here.

Tim Garrett is an extraordinary athlete. Not content with swimming some of the world's most famous and gruelling waterways, Tim tags on runs and rides of hundreds of kilometers to his swims. For instance, Tim has completed the Arc2Arch: Run - 87 miles from Marble Arch in London to Dover, Swim - The English Channel, Bike - 181 miles from Calais to the Arc de Triomphe in Paris. He is one of only two people to have completed the Arc2Arch and Uberman, an event in which you swim from 21 miles from Catalina Island to Los Angeles (a major event in itself!), cycle 400 miles to Badwater basin, the lowest point in North America, and then run 135 miles through Death Valley before ascending 13,000 feet to Mount Whitney, the highest peak in the Continental United States. He plans his own ultra-endurance events through his company Another Level Performance. Apart from Australia's longest open water swim, he has also organised Hard Bastard, where you: Swim - 35 km from Palm Beach to North Bondi, Bike - 620 km to Mount Kosciuszko, Run - 162 km in the Australian Alps. He fundraises for The Heart Research Institute and unsurprisingly doesn't sleep much! His major aim is to tackle the North Pole.

Wild swimming is something of a cousin to ocean swimming. Or is ocean swimming a subset of wild swimming? Either way, wild swimming is huge across the world, and particularly in the UK and Europe. It's also often stunningly beautiful - search #wildswimming on instagram and you'll see what I mean. Calum Hudson is the middle brother of The Wild Swimming Brothers, triathlete,Ice swimmer, author, nature love, swimming advocate and wild swimmer. He has swum the world's most powerful maelstroms, escaped Alcatraz and swum between continents. The Wild Swimming Brothers started with a 140 km swim down the River Eden, as you do! We had a wonderful chat about the whole gamut of things that make up the world of wild swimming.  Songs in this episode - all licensed under a Creative Commons License: Wild - Bank$ the producer Swimming - elesimo Brothers - Marcel Hutter Swimming - David Lassam Swimming in ink - Wontolla Sapphire - Tobu Image from The Wild Swimming Brothers on Instagram

Have you ever had the visibility in a swim drop to a few centimeters? Has it ever gone a bit brown? Perhaps you've ended up swimming through sewage! This happened to Dr. Ian Wright in the 90s, and is likely to have happened to any ocean swimmer who was swimming off the coast of Sydney in that period. Ian is a keen ocean swimmer and a senior lecturer in the School of Science and Health at Western Sydney University, whose research interests include freshwater ecology, water chemistry and water pollution. We chatted about the poo problem at Sydney's beaches.

Last time we talked about stingers, we learnt some valuable insights - don't wee on them! Turns out, there may be some better solutions on the horizon. Associate Professor Greg Neely, from the School of Life and Environmental Sciences at the University of Sydney, has discovered an antidote to the sting of the most venomous creature on Earth -  the Australian box jellyfish. Greg's antidote, discovered using CRISPR genome editing technology, blocks the symptoms within 15 minutes, and overlaps interestingly with research conducted into cholesterol. This means that the drug development may already be out there and we could see something in the hands of life-savers sooner rather than later.

Dr Gary Greenberg is a scientist, author, teacher and photographer who combines his passion for art and science by exploring the hidden small-scale dimensions of nature. Gary has invented multiple high-definition, three-dimensional light microscopes (for which he has multiple US patents) and nowadays focuses his microscopes on common objects, such as grains of sand, flowers, and food. He's looked at sand from all round the Earth, but the funkiest sand he has examined is from the Moon. He's hoping he can get some Mars sand! You can identify a beach (or heavenly body) from its sand, which depends on the temperature, surf and erosion conditions and marine environment.  You can see Gary's sand photography for yourself at And you might like to do some searching for the in vitro human pancreatic cancer cells he turned into the planet Kyrpton in the first Superman movie - the nuclei of the cells look like impact craters!

Ocean pools are a delight. I love swimming in them, and they are also quite often simply beautiful places to be. Dr. Marie-Louise McDermott has written a PhD on ocean pools (Wet, wild and convivial: past, present and future contributions of Australia’s ocean pools to surf, beach, pool and body cultures and recreational coasts) and runs a fantastic website dedicated to ocean pools, All into ocean pools inc. I had a wonderful chat with Marie-Louise about her love of ocean pools, why Australia (and Sydney in particular) has such a rich tradition of them, and their influence on Australian life.

Swimming caps are a large source of ocean swimming waste. Often only once used, destined for land-fill or the ocean itself, events have not got a handle on to how to appropriately use them. And despite popular belief, they do not break down in the environment in any useful timeframe. They are important facets of ocean swimming safety so that swimmers can be seen in the water and in their racing waves, but at the end of each season, even mediocre swimmers like myself end up with a bag full of caps, never to be used again. So, what can you do? I've been collecting caps for Recap over the last few summers to give them on to good causes. One of those places they go is Reverse Garbage, an organisation that saves materials from landfill and renews their value by making them available for reuse by families, students, artists and community groups. Each year, they take about 35 thousand cubic meters of waste for reuse, saving tonnes of raw material, energy and emissions. I spoke with Kirsten Junor, Creative Director at Reverse Garbage, about what she does with the caps, what Reverse Garbage does in general, interspersed with all sorts of reuse/recycle discussion. We recorded in the pub - surely the best way to spend an afternoon recording a podcast - so occasionally the sound quality dips.

Things that can sting you are part of every ocean swimming experience, not matter where you are in the world. Associate Professor Jamie Seymour, Director of the Tropical Australian Stinger Research Unit at James Cook University, studies venomous animals and has a particular interest in decreasing the envenomings of humans by jellyfish. He has some personal experience in this area too - he has been stung by Irukandji 11 times! He is a world leader in the studies of the ecology and biology of Box jellyfish (his favourite jellyfish), and his work has led to pharmaceuticals being made from animal venom. We chatted about how to treat ocean stings (not with vinegar nor, funnily enough, urine!), habitats and the influence of climate change on the spread of stingers, stinger evolution, the difference between poison and venom, and between a toxicologist and a toxinologist, and a host of other jellyfish tangents (tentacles?).

Rips claim an order of magnitude more lives than shark attacks in Australia, and are arguably the most dangerous facet of going to the beach. Associate Professor Rob Brander, also known as Dr Rip, is a coastal geomorphologist who studies morphodynamics (hydrodynamics, sediment transport, morphology) of coastal systems, with a particular interest in rips and the safety of beachgoers. He runs a beach education program called Science of the Surf, and one of the cool things he does is publish a Rip of the month. You might like to read his book, Dr. Rip's Essential Beach Book, or check out the National Geographic documentary, Rip Current Heroes. Coming into the summer, listen in as Rob lets you know how to spot a rip and what to do if you're caught in one.

Shark nets are fairly common across popular Australian tourist beaches, but beyond giving swimmers a perception that they are being protected from sharks, do they actually work? Jordan Sosnowski is the Advocacy Director for Action for Dolphins, a group that aims to stop cruelty to, and gain legal protection for, small cetaceans (dolphins and other small whales). We chatted about how shark nets probably don't work to keep sharks and swimmers apart, that shark nets have an incredible toll on marine life, that sharks don't hunt you down, that opinions on the use of shark nets are changing, and the non-lethal options that are out there.

Ram Barkai is the founder of the International Ice Swimming Association - they are all about swimming in water less than 5 degrees Celcius. Ram has swum many of the world's toughest swims, including in Antarctica, and holds multiple world records. The IISA introduced the Ice Mile as its signature achievement; the Ice Mile is one mile in water of 5C or less. The swim must be unassisted and only a pair of goggles, a cap and a standard swimming costume can be worn. In 2014, the IISA introduced the 1 km ice event, and Ram's ambition is to have the 1 km event introduced to the 2022 Winter Olympics. I've left this episode long as I found it absolutely fascinating, and Ram very entertaining!

The Cooks River in Sydney has been variously described as an open sewer, the River of Death, and one of Australia's most polluted rivers. Yet there are plans - possibly rather hopeful plans - to bring swimming back to the river. There are numerous such rivers in cities around the world, so how realistic is the idea that you could bring swimming back to polluted city rivers? Could ex-industrial rivers join the oceans (and dams) of Australia as recreational swimming spots? Professor Stuart Khan from the School of Civil and Environmental Engineering at UNSW studies sustainable urban water management, and has studied chemical composition of the Cooks River, and how the pollutants got there. He thinks that, whilst it may be a long way off, there are precedents around the world for bringing back swimming to polluted rivers. You can read more on efforts to remediate the Cooks River at the Cooks River Valley Association.

Beachwatch test the water quality of Sydney beaches to see if they are suitable for swimming. The program also partners with councils and wastewater managers for swimming sites along the NSW coast. Water samples are collected and tested for bacteria, which may suggest faecal pollution, and influence whether the beach is safe for swimming. The program started in 1989 due to sewage pollution washing up on Sydney beaches - there was literally poo on the beach... These days, water quality has greatly improved, largely due to new deep ocean outfalls for coastal sewage treatment plants, as well as improvements in wastewater and stormwater management. The major reason why a beach may be unsafe to swim these days is because of recent rainfall, which can bring stormwater and wastewater overflow. Beachwatch also provides weekly star ratings for beaches, and the annual State of the Beaches report. Dr. Meredith Campey is the Beachwatch Program Manager, and I spoke to her about what Beachwatch does, its history, how they test and what they test for, and the various reasons a beach may be unsuitable for swimming. You can receive Beachwatch updates on Facebook and Twitter, subscribe to their RSS feeds, or subscribe to daily pollution forecasts.

It is estimated that ocean plastics will outweigh ocean fish by 2050, according to a study by the World Economic Forum. There are at least 5.25 trillion plastic pieces floating in the oceans right now. Dr. Jennifer Lavers is a Research Scientist at the Institute for Marine and Antarctic Studies at the University of Tasmania. She is a marine eco-toxicologist with expertise in tropical and temperate seabird ecology, plastic pollution (marine debris), invasive species management, and fisheries by-catch. Her research examines how marine apex predators, such as seabirds, act as sentinels of ocean health, and focuses on pollutants of aquatic ecosystems such as plastic, heavy metals, Persistent Organic Pollutants (POPs) and radionuclides. She is also very interested in science and conservation outreach. Jennifer also has an Erdos-Bacon number, as a star of the stage and screen, as well as of academia! I chatted to Jennifer about her work, starting with her article This South Pacific island of rubbish shows why we need to quit our plastic habit.  Songs in this episode - all licensed under a Creative Commons License Happy Life - Fredji Acoustic guitar arrangement for song - TRow A new beginning - Bensound Buddha - Kontekst Sapphire - Tobu

Can you ocean swim on other planets? Perhaps! Water is far more common in the Universe than you might think, and there are many other oceans out there, even on our neighbours in our own solar system. Associate Professor Jonti Horner is an astronomer and astrobiologist who works in the Computational Engineering and Science Research Centre at the University of Southern Queensland. We caught up at the Australian Space Research Conference. It is currently thought that there are oceans deep beneath the surface of some of Jupiter's and Saturn's moons, as well as astonishingly, on asteroids and Pluto. The Saturnian moon Titan, as well as likely having a subsurface water ocean, may have standing hydrocarbon oceans on its surface. Mars and Venus may have had oceans in the past. And it's almost certain that outside the solar system, there are planets just like Earth with vast water oceans. Could these locations be the home of future extreme sports? We also chatted about publically funded science, future space missions and the future of Earth.

A Melbourne man recently emerged from the ocean with his legs covered in blood seeping from thousands of tiny wounds. Dr. Murray Thomson from the School of Life and Environmental Sciences at The University of Sydney, thinks that Cirolana harfordi, a small crustacean that lives on the coast and in rivers, may have been to blame. These creatures have been known to take down sharks, have bitten divers on the face and have even skeletonised the top half of a human, using their slicing, guillotine-like mouth parts. If they're around where you're swimming, you've probably got about 10 minutes to get out of the water! I chatted to Murray about his research into these fascinating (terrifying...) creatures, their various types and behaviours, as well as their evolution and precautions you should take if you think there may be Cirolanids around.
