Top 9 Scary Animals In Australia

Did You know that Australia has the deadliest snakes out of all countries in the world?

Snakes naturally start putting shivers down our spines. The way they move about is peculiar and is mostly associated with causing deadly bites (even though most snakes are in fact harmless).

But snakes aren’t the only scary animals in Australia or the waters surrounding it. There’s plenty of other monsters you wouldn’t want to come across in your lifetime.

Do you remember the late Steve Irwin, the famous wildlife expert? Perhaps you know him better by his nickname the “Crocodile Hunter.”

He was actually killed by a stingray.

In this list, we’ll present you with a bunch of scary animals in Australia, the country down under.

1. The Sydney funnel-web spider

Where do you think the Sydney funnel-web spider lives?

You guessed it: In Sydney, Eastern Australia.

In fact, most of the population of this venomous mygalomorph is found within a 100-kilometer radius of the Australian city.

If the bite is left untreated, it can be deadly to humans and initial symptoms of the deadly venom include serious pain, disorientation, muscle twitching and even becoming unconscious.

In other words, if you get bitten by this scary animal, make sure to call an ambulance that will bring you to the nearest hospital as soon as possible.

2. Coastal taipan snake

One of the most dangerous snakes in Australia is the coastal taipan snake, or simply known as the taipan.

It is found around the coastline of Northern and Eastern Australia, and can also be found on the island of New Guinea.

It’s not only one of the most venomous snakes in Australia, it’s also the longest venomous snake, making it even scarier.

If you are unlucky enough to come across the path of the taipan snake and actually get bitten, you might experience nausea, vomiting, and even internal bleeding as its venom directly affects the nervous system. A single bite might kill you within 30 minutes.

Luckily enough, it’s very rare for humans to ever encounter this snake and the unlucky ones are mice, rats, and birds.

3. Irukandji jellyfish

Think about taking a nice dive into the ocean in Northern Australia? You might think twice after reading about the Irukandji jellyfish.

The Irukandji jellyfish is a type of box jellyfish that floats around the coast of Northern Australia and is one of the most venomous types of jellyfish in the world.

To make it even worse, they are also one of the smallest types of jellyfish with a size of just one cubic centimeter, making them very hard to spot in the ocean.

If you’re unlucky enough to get stung by the Irukandji jellyfish, the venom is strong enough to cause deadly brain hemorrhages.

Nearly 100 people are admitted to the hospital every year after going through this ordeal.

4. Cassowary

The Cassowary is a type of running bird similar to ostriches that live mainly in the tropical forests of Papua New Guinea, Indonesia, and the Maluku Islands, but are also native to northeastern Australia.

The grim look on their faces isn’t fake as they have a reputation for being hostile towards humans. Over 100 attacks on humans have been recorded in history, several with lethal consequences.

The reason why they are so dangerous is that one of their toes is actually fitted with something resembling a nail, which can cause massive damage.

Our advice: If you ever come across a Cassowary, don’t try to feed it or attack it and get the heck out of its sight as soon as possible.

5. Tasmanian Devil

The Tasmanian Devil gives you a lot of reasons to be scared. Some characteristics of this carnivorous animal include having a stocky, muscular built, having a smelly and unpleasant odor, making a very loud screeching noise, and having the strongest bite based on the per-unit body mass of any land predator.

They used to live in the wild in mainland Australia, but can now only be found in the wild on the island of Tasmania.

Frequent fights amongst Tasmanian Devils break out as they are far from being monogamous, and the female Tasmanian Devils are often the reason for a head-to-head in the arena.

Funnily enough, the winner will guard his woman to prevent other interested parties from doing exactly what he did. The more fights he wins, the more women he needs to protect.

Apart from their scary looks, name, and aggressive behavior when it comes to relationships, Tasmanian Devils aren’t dangerous to humans. As with all animals though, they will defend themselves when attacked.

6. Saltwater Crocodile

Found in Northern Australia, saltwater crocodiles not only look frightening but are also extremely dangerous for humans.

It’s one of the biggest crocodiles on the planet and males reach up to 6 meters (25ft) and weigh over 1,000 kilos (2,200lb).

Because saltwater crocodiles don’t care what they have for lunch that particular day, coming across a hungry one is extremely dangerous for humans if you happen to wander off in the habitat.

Because of their speed and hunting ability, along with their immense size and weight, surviving an attack is virtually impossible as soon as the saltwater crocodile gets a hold on you with its enormous mouth.

This is one reptile you never want to come across in your lifetime, that’s for sure.

7. Australian paralysis tick

Tick’s are parasites and are naturally scary. What makes the Australian paralysis tick even scarier is the fact that they are so common and mainly live in populated areas of Eastern Australia.

When an Australian paralysis tick bites, it inserts neurotoxins in the host’s body causing, as you would have thought, paralysis.

While humans mostly only feel a severe itch and numbness in the area where the poison has been inserted, it can cause life-threatening effects if you happen to be allergic to the tick’s poison.

If you happen to live in or visit Eastern Australia, you now know what has happened if you suddenly feel an intense itchy sensation.

8. Redback spider

The redback spider is also known as the “Australian Black Widow.” It’s an extremely venomous spider found in the South and Eastern deserts of Australia.

The adult female redback spider is the most dangerous and can easily be recognized by the red stripe on its back.

If you see one of these, you don’t necessarily need to worry that they will suddenly attack as is the case with venomous snakes, are they are very slow movers.

If you suffer from arachnophobia however or even a mild form of this phobia, you will certainly get scared to death when coming across the redback spider.

In case a human is bitten by the Australian black widow, the bit may become life-threatening if the bite isn’t treated with antivenom, which is easy to get by these days.

Either way, it’s best not to come across the path of this venomous spider altogether.

9. Tiger Snake

Because Australia is home to the world’s largest population of venomous snakes in the world, and because a lot of people are scared to death of snakes, let’s finish off this list with the tiger snake.

The tiger snake is found in the Southern regions of Australia and is extremely venomous.

If bitten by the tiger snake, you would feel severe pain in your foot and neck, followed by nausea, dizziness, heavy sweating, and find it increasingly more difficult to breathe.

The chances of surviving a bit from the tiger snake if left untreated are about 40-60%, so it’s recommended you visit the hospital instantly after the event.

To make things even worse, tiger snakes look like one of the scariest animals in Australia as well.
