Things About Australia You Need To Know Before Visiting

Australia is a popular tourist attraction, commonly known for their beautiful beaches, but don’t be fooled by the facade. Australia is home to some of the most dangerous animals and poisonous insects on the planet. While it may not be enough to deter you from visiting or living there, you definitely should be aware of what you’re up against, whether it be a tiny spider or a great white shark.

Box jellyfish

Commonly found floating along the Great Barrier Reef, the sting of a box jellyfish can cause excruciating pain and sometimes fatalities. Each corner of the jellyfish has about 15 tentacles, each containing about 500,000 cnidocytes, which are explosive cells that inject venom into the victim.

This is what a box jellyfish sting looks like. Ouch!

Common symptoms of a box jellyfish sting include burning, prickling, and stinging pain. You will see the ‘print’, or tracks, of the tentacles like in the photo below. Then comes the throbbing pain. Sounds awful, right? That’s because it is. If the sting is really bad it’ll progress to nausea and vomiting, headaches, muscle and joint pain.


1. Pythons are this big. 2. Flying foxes (which pretty much look like the modern day pterodactyl) exist. And 3. Pythons eat flying foxes. No thank you, Australia.

Pythons are strong!

Pythons are strong enough to pull wallabies up out of the water. Wow.

Blue ring octopus

Merely growing up to 5 to 8 inches, the blue ring octopus is one of the most venomous creatures in the ocean. There is no antidote to its venom, which is powerful enough to kill humans.

Always gotta watch your back

Sometimes it’s not the little octopus you have to worry about…but the big one. You know, the ones that attach to your back!


A stonefish can look like a rock or coral reef but it is one of the most venomous fish in the world. The spines on the dorsal fin inject toxic venom that cause immense pain and possible death.

Ummm, no thanks!

This is what happens when you come in contact with a stonefish.

Just get use to seeing sharks

Australia is home to three of the most dangerous sharks in the world: the bull shark, the tiger shark and the great white. All are likely to attack humans. I sure hope that surfer made it out okay and didn’t get attacked by the great white swimming by him.

You know this guy

The great white shark can grow up to 21 feet and is responsible for the most reported unprovoked attacks on humans, even though humans are not their choice of prey.

Tiger shark

The tiger shark falls second to the great white on attacks towards humans. Though most attacks are not fatal, tiger sharks often dwell along shallow reefs, harbors, and canals, giving them many opportunities to encounter humans.

Bull sharks

Bull sharks are extremely aggressive by nature and lurk in warm, shallow waters, giving them more interaction with humans than any other shark.

Tasmanian devils

Tasmanian devils, found only on Australia’s island state of Tasmania, is considered the largest carnivorous marsupial in the world.

Coconut crabs

Being pinched by these alien-like creatures called coconut crabs cause excruciating pain, not because they’re poisonous,f but because they hold their grip for a long time.
