30 Creepy Crawly Reasons Why Australia Might Just Be The Deadliest Place On Earth


For many, Australia is a bucket-list vacation destination, full of amazing culture, warm oceans, and awesome accents. However, Australia is also home to some of the deadliest wildlife on the planet. What’s more, you’ll find plenty of species capable of harming you no matter where you look, be it sea or land. That’s not to say it isn’t still a great place to visit, but forewarned is forearmed. Your dream vacation in the land down under can quickly take a scary turn if you aren’t prepared for what awaits you. Here are 30 of the most dangerous animals you’ll find “down under.”

Box Jellyfish

Australia has some of the best shores you’ll find in the entire Pacific Ocean. Many consider it one of the top surfing destinations on the planet. However, the waters around Australia are also home to some of the deadliest species in the sea.

Take the Box Jellyfish, for instance. Its sting is one of the most painful on the planet, and it can even kill you. What’s worse, the animal is nearly invisible in the water, so it’s hard to spot them before it’s too late.

Funnel-Web Spider

If you’re not a fan of spiders, you might want to seriously have a self-intervention before vacationing in the land down under. Australia is home to many different species of arachnids, including the funnel-web spider. This little guy is one of the most venomous spiders in the world.

They get their name because the webs they create are funnel-shaped so that their prey can’t escape once they enter. The symptoms of a bite from a funnel-web spider are not pleasant, and the bites can be fatal to humans.

Saltwater Crocodiles

The saltwater crocs that call Australia home are probably the closest thing to a living dinosaur that you’re ever likely to encounter. And believe us, you do not want to encounter one in the wild!  The can grow up to 20 feet long and way more than 2 tons.

They’re also very fast and can lunge out of the water to snap up prey in the blink the of an eye. If you’re unlucky enough to get bitten by a saltwater croc, you’ll get an up-close view of more than 60 teeth and the strongest bite pressure of any living animal on the planet.

Kangaroos are cute and cuddly, right?  While the answer is “yes,” they’re also very dangerous to humans. They’re incredibly fast, and they can move at speeds of up to 44 miles per hour. If one of these cute little guys connects with you at that kind of speed the damage could be pretty severe.

Plus, kangaroos are incredibly aggressive fighters. The males will compete for females by punching, kicking, and biting each other. If you happen to be near when one of these brawls goes down, you could easily be dragged into the fight!

Cone Snails

A deadly snail?  If we’re talking about Australia then you bet!  The cone snail has a circular shaped tooth that it fires out of its mouth to latch onto its prey and that sometimes includes the feet of humans. Getting bit is like a nightmare.

Oftentimes, people don’t even realize that they’ve been stung until its too late and their bodies are pumped full of neurotoxins that can shut down speech and vision.  These snails are usually found around reefs in both the Indian and Pacific Oceans.

Giant Centipedes

If this one doesn’t give you nightmares, we don’t know what will!  These alien-looking animals can grow to more than 6 inches. That’s a lot of ground to cover for a bug. They also come with a nasty pair of claws that can deliver venom into its prey.

While not usually fatal to humans, the stings can be incredibly painful. Some victims have compared it to a wasp sting, while others have reported that a sting from a giant centipede is one of the most intense pains they’ve ever felt. We’d suggest not finding out one way or the other.

Coconut Crabs

Have you ever tried to crack open a coconut with your bare hands?  You probably can’t do it as most people can’t. But these giant crabs can and with absolute ease!  They’re found throughout the islands in the Pacific Ocean east of Australia.

The coconut crab is the largest crab on land anywhere in the world. Their claws are so powerful they could easily break the bones of a human. With that said, if there’s only one coconut left and one of these things wants it, we suggest you give in.

Redback Spider

Ah, another spider. The redback spider of Australia is a particularly nasty species. Once its prey gets tangled in a web, the spider will wrap it in silk and then suck out the insides. That’s after it bites the head a bunch of times for good measure.

Humans who get bitten by Redbacks often have to undergo a course of antivenom.  Like America’s Brown Recluse, these spiders live in places where human contact is quite possible. They’re found in clothing, shoes, and the walls of homes.

Giant Snakes

It’s probably no surprise to learn that Australia is home to some of the most venomous snakes in the world. What’s worse, though, is that it’s also home to snakes so big they could likely swallow you whole.

A few years ago, this image surfaced on the internet and shows the final scene in a fight between a crocodile and huge snake. It would appear as if the snake won the battle.  If this one doesn’t give you nightmares, then nothing will!

Giant Birds

As if being home to giant snakes wasn’t enough, Australia also has giant birds. Take the fuzzy Cassowary. They’re a cross between a turkey and an ostrich and they can grow up to 6 feet tall. They can also jump over 5 feet into the air and run at speeds of up to 31 miles per hour.

They can’t fly, but they can swim, so if you were thinking of jumping into the crocodile-infested waters to escape one you might as well come up with another plan. The Guinness Book of World Records has named this goofy bird the world’s most dangerous.

Red-Bellied Black Snake

The good news is that this snake is pretty easy to identify. As the name implies, it’s black on top and red on the bottom. It’s pretty common in urban areas throughout Australia, so encounters with humans happen frequently.

A bite from one of these snakes usually won’t kill you, but you do need to get medical treatment as soon as possible. A bite from a red-bellied black snake is very painful, and it will cause vomiting and diarrhea in humans.

Great White Sharks

The Great White is one of the top predators in the ocean and Australia is home to a lot of these sharks. A bite from a Great White does a lot of damage, thanks to the more than 200 razor-sharp teeth the animals have in their mouths.

Divers and surfers should take extra care when in areas known for Great Whites. In fact, many new products are on the market that can be worn which will transmit an electromagnetic pulse, thought to repel the big predators.

More Snakes Eating More Nightmarish Animals

Here’s yet another example of how Australia is home to some of the most nightmarish natural occurrences on the planet. In this image, we see a cuddly python crushing and devouring a flying fox. This is a pretty intense looking snake.

While the bat-creature may seem cuddly to some, it’s important to note that the flying foxes carry some pretty nasty diseases that can be fatal to humans. In that sense, many Australians actually like the fact that there are giant, horrible snakes prowling around to keep the bat population down.

Many of the deadly creatures on this list are cute and cuddly on the surface. The Stonefish is not one of those creatures. It’s ugly and it’s dangerous as hell!  The fish is covered in spines that can deliver venom into its victims capable of not only causing some of the most intense pain imaginable but even death.

They look like rocks, so it’s easy to get way too close to them without warning. You can step right n this fish without realizing it. The good news is that when prepared correctly, they’re edible and very delicious!

Strychnine Tree

Even the fruit in Australia can kill you. While the small, orange fruit pictured here might look refreshing, you should, under no circumstances, ever eat it!  The fruit contains seeds that are incredibly toxic to humans.

Consuming the seeds will affect the central nervous system, causing everything from convulsions to death. The rest of the tree is just as dangerous, too. Even the bark and leaves are poisonous if humans come in contact with them. In short, if you’re craving fruit while down under, stick with the supermarket.

Giant Hail

This one is a bit of a cheat but it’s still worth mentioning. This list is primarily made up of animals with the occasional plant thrown in. However, this entry is one of Mother Nature’s more surprising killers. The storms in Australia can get pretty wicked, too. Need proof?

Just check out this image that was posted in 2013. It shows hailstones the size of billiard balls that had just fallen from the sky. Make no doubt about it, if one of these things connects with your skull, you’ll end up with a hell of a headache, at best.

The dingo is an interesting creature. It’s a wild dog that roams the outback in packs. There aren’t many reports of attacks on humans, but there have been a few. In most cases, people mistook the animals for domesticated dogs and tried to feed them. All the more reason to take caution if you’re a tourist.

The dingoes pose the biggest problem to farmers and their livestock. They can easily kill cattle and other animals. That’s why a giant fence—nearly 3,500 miles long—was constructed across Southeast Asia, just to protect the livestock from the wild dogs.

The Landscape

Make no mistake, the Australia Outback is a desolate piece of land. If you plan to travel across it, you’ll need to plan carefully. There can be hundreds of miles between fuel and watering spots, so you’ll need pack extra in your vehicle before setting out.

The cell service across the Outback is spotty at best, so you won’t always be able to get ahold of someone if you run into problems. That means you need to be completely comfortable with surviving on your own for several days sometimes with no contact with other people.

Irukandji Jellyfish

The ancient Jedi Master Yoda once said, “size matters not.”  When it comes to the jellyfish that call Australia’s waters home, truer words were never spoken. Take the Irukandji jellyfish picture here. It barely grows to a cubic centimeter in size, but that doesn’t mean it can’t pack a wallop of a sting.

If it injects a human with its venom, that person is almost guaranteed a visit to the hospital, where they’ll most likely be suffering from nausea and horrible muscle cramps. This little animal is primarily found in Australia’s northern waters.

Like the landscape in Australia, the climate in the Outback can be just as deadly as many of the country’s deadliest animals. Just how hot does it get?  It’s pretty common in the summertime to see temperatures exceed 120 degrees Fahrenheit on a regular basis.

That’s hot enough to fry an egg on the pavement. It can be deadly for those not prepared, too. Back in 2009, a weeklong stretch of such temperatures left 374 people dead throughout Australia, according to health officials in Victoria.

Eastern Brown Snakes

Now we’re getting into the seriously dangerous territory, folks. We’ve already established that Australia has some snakes capable of swallowing crocodiles whole and delivering some painful bites, but a bite from an Eastern Brown Snake has the serious potential to be fatal.

The Eastern Brown is the second most venomous snake in the world and has killed more than 20 people in Australia since 2000. A bite can cause uncontrolled bleeding and cardiac arrest and can prove fatal in as little as 15 minutes if not treated.

By land or by sea, you’ve seen that Australia has plenty of dangerous animals to keep you on your toes. Here’s another example of the aquatic variety. The lionfish is a beautiful species to look at, but don’t get too close. That’s because a sting from one of these fish can inject venom into your system that can cause some serious problems.

The stings are not only extremely painful, but the venom can cause everything from vomiting to paralysis. It’s a bad fish, so keep your distance when you spot one while diving or surfing. This will definitely make your day an unpleasant experience.

The Ocean Itself

We’ve established that waters around Australia have plenty of animals around that are more than capable of ruining your day, or worse. Great whites can devour you, while tiny jellyfish and camouflaged stonefish can deliver painful stings that can do everything from hurt like hell to actually paralyze you.

However, the sheer power of the ocean around Australia can be just as deadly. Waves can reach 40 feet in height at times, and that kind of power can easily crush a human if they’re in the wrong place at the wrong time.
