If you’re walking through the button grass plains of the Southwest National Park or just hanging out in a leafy backyard in Hobart, there is a thought that eventually crawls into the back of your mind. It’s the rustle in the dry leaves. The shimmer of scales near a log. You’ve heard the stories. Tasmania is famous for its wilderness, but it's also famous for having exactly three species of land snakes, and—here is the kicker—all of them are venomous. Honestly, it sounds terrifying to a visitor. People talk about poisonous snakes in Tasmania like they’re waiting behind every bush to ruin your weekend. But the reality is way more nuanced, and frankly, a lot less scary once you understand how these animals actually operate in the Tasmanian bush.
First off, let’s get the terminology right because it matters. Technically, these aren't "poisonous" snakes—they’re venomous. Poison is something you inhale or eat; venom is injected. If you bit a snake, that would be a poisoning problem (and a very weird day). If the snake bites you, that’s a venom problem.
Tasmania’s "Big Three" are the Tiger Snake, the Lowland Copperhead, and the White-lipped Snake. That’s it. No pythons. No brown snakes. No red-bellied blacks. Just three variations of elapids that have adapted to the often-freezing temperatures of the island.
The Tiger Snake: Tasmania’s Heavyweight
The Tiger Snake (Notechis scutatus) is the one everyone worries about. And for good reason. They are hefty. They are fast. They have a reputation for being "cranky," though most herpetologists, like the legendary Tasmanian snake catcher Bruce George, will tell you they just want to be left alone.
In Tasmania, Tiger Snakes don't always look like tigers. You might expect bright yellow and black stripes, but because of the colder climate here, many individuals are melanistic. They’re jet black. Darker skin helps them soak up the limited Tasmanian sun more efficiently. It’s a survival hack.
These snakes are everywhere—from the coastal marshes to the suburbs. They love water. If you see a snake swimming in a creek near the Derwent River, it’s probably a Tiger. They eat frogs, lizards, and even small birds. Their venom is a potent cocktail of neurotoxins, coagulants, and hemolysins. It’s serious business. If you get bitten, your nervous system starts shutting down, and your blood loses its ability to clot. But here is a bit of perspective: deaths are incredibly rare. Why? Because we have some of the best antivenom in the world and Tasmania’s medical teams know exactly what they’re doing.
Why the Lowland Copperhead is Misunderstood
Then you have the Lowland Copperhead (Austrelaps superbus). Don't confuse these with the copperheads found in North America; they aren't related. The Tasmanian version is much more robust.
Copperheads are the tough guys of the snake world. They are active in temperatures that would make a Tiger Snake go into a deep sleep. I've seen them out on days where I was wearing a thick puffer jacket. They have a beautiful, often reddish-orange flush along their lower flanks, which is a key way to tell them apart from a dark Tiger Snake if you’re close enough—though staying close enough to check is usually a bad idea.
They are generally shy. Most of the time, a Copperhead will sense the vibration of your boots and disappear into the scrub before you even see its tail. They live in the wetter parts of the state. Think marshes, soakages, and the edges of lagoons. If you're hiking the Overland Track, you'll likely pass dozens of them without ever knowing they were there.
The White-lipped Snake: Small but Not Harmless
The third member of the trio is the White-lipped Snake (Drysdalia coronoides). It’s the "little" one. Usually, they don't get much longer than 40 or 50 centimeters. They look almost cute. They have a distinct white stripe running along their upper lip, hence the name.
Because they’re small, people tend to be less afraid of them. That’s a mistake. While a White-lipped Snake doesn't carry the massive venom load of a six-foot Tiger Snake, they are still venomous. A bite will cause significant pain, swelling, and potentially a systemic reaction. They are the most common snake found in high-altitude areas. If you’re at the top of Mount Wellington/kunanyi and you see a small, slender snake darting under a rock, that’s your culprit.
Understanding the Venom: What Actually Happens?
It’s easy to get caught up in the horror stories. You’ve probably heard that poisonous snakes in Tasmania can kill you in minutes. That is mostly a myth. While a bite is a medical emergency, the onset of life-threatening symptoms usually takes a bit of time—hours, not minutes.
The venom of Tasmanian snakes is designed to catch prey, not kill humans. We are way too big to eat. When a snake bites a human, it’s a defensive move. It’s terrified.
- Neurotoxins: These target your brain-to-muscle communication. This leads to drooping eyelids, difficulty breathing, and eventually paralysis.
- Procoagulants: This is the scary part. The venom consumes your body's clotting factors. You don't necessarily "bleed out" like in a movie, but your internal chemistry goes haywire.
- Myotoxins: These break down muscle tissue, which can eventually lead to kidney failure as the debris clogs up your system.
The Reality of Snake Encounters in the Bush
Most people spend their whole lives in Tasmania and never get bitten. It's actually quite hard to get bitten. You usually have to step on one or try to kill it.
I remember talking to a bushwalker who had been traversing the Walls of Jerusalem. He told me he’d stepped right over a Tiger Snake that was sunning itself on a boardwalk. The snake didn't even flinch. It just sat there. Snakes are incredibly energy-efficient creatures. Attacking a giant mammal that is 50 times its size is a waste of energy and a massive risk for the snake.
Statistics show that the vast majority of snake bites in Australia happen to people (mostly men) who are trying to catch or kill the snake. If you see one, just stop. Give it a few meters of space. It will move. Honestly, they’re more scared of you than you are of them. Your heavy footsteps feel like thunder to them.
Myths vs. Reality
Let's debunk a few things.
First, snakes do not "chase" people. A Tiger Snake might move toward you if your only exit path is the same as its only escape route to its hole. It’s not hunting you; it’s panicked and trying to get to safety.
Second, baby snakes are not "more dangerous" than adults. This is a common old wives' tale suggesting babies can't control their venom flow. While it's true they might be more nervous, an adult snake has a vastly larger reservoir of venom. A big snake is always a bigger risk than a small one.
Third, don't worry about "mother snakes" protecting their young. Tasmanian snakes give birth to live young (they are viviparous), but once those babies are out, they are on their own. There is no maternal protection. There are no "nests" of angry snakes waiting to swarm you.
What to do if you’re bitten
If the worst happens, forget everything you saw in old Western movies. Do not cut the wound. Do not try to suck out the venom. Do not apply a tight tourniquet.
The Australian standard for snakebite treatment is the Pressure Immobilisation Technique (PIT).
- Stay still. This is the most important part. Venom moves through your lymphatic system, not your bloodstream. If you run for help, your muscles pump the venom straight to your heart. Stay dead still.
- Apply a broad pressure bandage. Use a heavy elastic bandage (like a Crepe bandage) and wrap it as tightly as you would for a sprained ankle. Start at the toes or fingers and wrap all the way up the limb.
- Splint the limb. Keep it immobilized.
- Call 000. Even if you think it was a "dry bite" (where no venom was injected), you need a hospital.
Hospitals in Tasmania, like the Royal Hobart or the LGH in Launceston, carry polyvalent antivenom. They don't even need to know which snake bit you to treat you, though they can often figure it out using a Venom Detection Kit (VDK) on a swab from the bite site.
Living with Snakes: A Tasmanian Perspective
In Tasmania, snakes are protected species under the Wildlife (General) Regulations 2010. It is illegal to kill them. This surprises some people who grew up with the "the only good snake is a dead snake" mentality. But snakes play a massive role in the ecosystem. They keep the rodent population in check. Without them, we’d be knee-deep in rats and mice.
If you have one in your garden, don't reach for the shovel. Call a professional. There are licensed snake catchers all over the state—people like the team at Reptile Rescue Tasmania. They’ll come out, bag the snake, and release it in a safer spot.
Practical Steps for Staying Safe
If you’re planning on exploring the Tasmanian wilderness, or even just gardening in a bushy area, here is how you stay off the casualty list.
- Wear long pants and gaiters. Most bites occur on the lower leg. A pair of sturdy canvas gaiters is almost impenetrable to a snake’s fangs.
- Watch your step. Don't step over logs where you can't see the other side. Step onto the log first, then look down.
- Carry a PLB. If you’re hiking solo in the Southwest or the Highlands, a Personal Locator Beacon can save your life if you're bitten and can't walk out.
- Keep your yard tidy. Snakes love piles of corrugated iron, overgrown grass, and stacks of firewood. If you keep the area around your house clear, they won't have anywhere to hide.
- Don't rely on "snake repellers." Those vibrating stakes you stick in the ground? They don't work. Scientists have tested them; snakes don't care. Save your money.
Tasmania’s snakes are a sign of a healthy environment. They are ancient, specialized survivors that have managed to thrive in one of the world's most rugged landscapes. Respect them, give them distance, and you’ll find that sharing the island with them isn't nearly as stressful as the rumors suggest.
Essential Gear for Tasmanian Hikers
- Two heavy-duty crepe bandages (10-15cm wide) kept in an accessible part of your pack.
- Sturdy leather or synthetic hiking boots that cover the ankle.
- A first-aid guide that specifically details the Pressure Immobilisation Technique.
Always let someone know where you are going and when you expect to be back. The "poisonous snakes in Tasmania" are just another part of the wild, like the unpredictable weather or the rugged terrain. Treat them with the same caution and respect you’d give a sharp cliff edge or a cold river crossing.
✨ Don't miss: Why the Victoria and Albert Museum Still Matters More Than Your Local Gallery
Check your local council website for a list of registered snake catchers in your area before the summer heat hits. Having that number saved in your phone can turn a stressful garden encounter into a quick, professional relocation. For those heading into the national parks, stop by the visitor centers at Cradle Mountain or Mount Field; the rangers there have up-to-the-minute info on where snakes are currently active on the trails.
