Australia, that paradisiac island… The beaches, the rangelands, the mountains, the deserts… Australia’s geography is as diverse as it is beautiful. And as its variety of geography, so is its biological kingdom.

Oh, you might be thinking about the koalas, the kangaroos, and how to forget the cute wombats? But, in fact, I was making reference to some other animals that coexist with the friendly wombats. It is not a coincidence Crocodile Dundee staged in Australia.

So, if you were planning a real Australian adventure, you may want to check these 10 creatures that you might not only run into over your trip but actually, they could kill you. Be aware, for we’re not exaggerating at all.


10. Giant Centipedes

Giant centipedes can grow up to 6 inches, making it a real nightmare. But its aspect is not all. The insect claws are poisonous. Its sting might cause a burning pain that could last for 12 hours straight. Definitely, do not mess with these fellows.


9. Cone Snails

Who would say snails would be a horrifying creature? Well, this is because you haven’t seen a cone snail before. This mollusk has the peculiar ability to launch out of its mouth a non-rad radular tooth and use it as a harpoon against its prey or whatever the snail feels to protect from, like let’s say your foot. Oh, and I forgot to tell you, the tooth is venomous.


8. Eastern Brown Snakes

Okay, get this: easter brown snakes are the second most venomous snakes in the world. They live all around the country, from east to north coasts inside barns and country homes. They are pretty peaceful, their bite can cause such a terrible pain that could actually kill you.


7. Cassowaries

The cassowary is a typical bird from Australia. It can get as tall as 6 ft (182 cm), it can jump as high as 5 ft (152 cm), and it can run at speeds up to 31 mph. If that wasn’t enough, it can swim. So, believe me, you have no chance of running or hiding from a cassowary. Cassowaries are responsible for attacking hundreds of humans every year, and for some fatalities too.


6. Box Jellyfish

Also known as sea wasp or fire medusa, box jellyfish are very dangerous since it is considered as the most lethal and toxic animal on the planet. Its venom attacks your heart, your nervous system, and your skin. All at the same time. Its transparent color and pale blue make it hard to spot it, so stay away from water in Northern Australia, especially between October and May.

5. Blue-Ringed Octopus

Its looks are indeed amazing but do not dare to touch it. These blue-ringed octopuses are venomous. Its sting is fatal since it paralyzes your body and shuts it down. Breathing becomes more difficult until it is just impossible. And besides, there’s no antidote for its poison.


4. Stonefish

Well, as you can see, Australian waters are pretty dangerous. Another animal you might find swimming around is the stonefish. The stonefish usually camouflages, so it is very difficult to spot it and thus prevent getting too close. Its venom is lethal so don’t touch them.


3. Spiders

Okay, let’s come back to earth. We probably are safer on land, but no. Australia is home to 520 species of spiders. Most of them are extremely venomous. Take for instance the Sydney funnel-web spider, the most venomous spider in the world.


2. Saltwater Crocodiles

Back to the sea, you might trip over a croc. Just a saltwater crocodile that can be over 20 ft (6 meters) long and weigh 4,400 lbs (almost 2,000 kg). Their daily diet includes sharks, tigers, and bears. They have no predators. Come on, who would eat these creatures?


1. Great White Shark

Imagine you go to Australia to experience the surfing life. But suddenly you hear “Shaaaark”… Uh, oh. Right? Well, Australian beaches are packed with sharks, and not any sharks, great white sharks. So between the sharks and the saltwater crocodiles, I wouldn’t recommend getting a swim too deep in the Australian ocean.
