One of the most common things to come up when talking about Australia is the number of animals that can kill you, most of which can only be found here. Many people believe this is because of the country’s separate land mass; migrating animals were never able to reach the island, while the animals in Australia were forced to develop ways of protecting themselves against the others isolated on the island with them.
Whatever the reason, Australia is indeed home to some of the deadliest animals in the world, but it’s also home to some of the most adorable creatures, including over two-thirds of the world’s pouch-baby species (marsupials), koalas and the cute but dangerous Tasmanian devils. Let’s have a look at some of the creatures you might come across when visiting this stunning country and a few facts about Australian animals.
Dangerous Australian animals
It’d be difficult to start a list of animals in Australia without putting the most sought-after information on the top: Australian wildlife one should be wary of, from the highly venomous to poisonous Australian animals. Well, here are a couple of creatures to look out for while hopping around Down Under.
Box jellyfish
It might be surprising to many that the most lethal thing to humankind in Australia is a small, pale blue, transparent creature that floats in the water, but it’s true. The box jellyfish, otherwise known as a sea wasp or boxfish, has a 10/10 rating and is considered to be the most toxic animal on the planet.
They’re typically found in Northern Australia and are most prevalent from October to May. The jellyfish sting is said to be searingly painful and affects the breathing, movement and nervous system of the victim, which can ultimately lead to death via cardiac arrest in mere minutes.
First responders in Queensland are trained to deal with these situations and offer various remedies and assistance on the beaches, including a handy bottle of vinegar, which is said to work better than urine (which can make the sting worse).
Blue-ringed octopus
Native to the Pacific Ocean, the blue-ringed octopus is one of the most venomous Australian animals, despite its psychedelic coloring and miniature stature making it seem adorable rather than deadly. The venom of a blue-ringed octopus is said to be more than 1,000 times stronger than cyanide, and one octopus can kill more than 25 humans in mere minutes. They tend to hide in coral reefs, sandy tide pools or crevices, marine debris, or shells.
If you find yourself face to face with this striking creature, keep calm and back away as quickly as you can. The bite is typically painless, so you may not know you’ve been bitten. Luckily, the blue-ringed octopus is only known to bite when handled or cornered and there haven’t been any recorded deaths by this octopus since the 60s.
Saltwater crocodile
It’s estimated that there are over 100,000 saltwater crocodiles in Australia, mostly found in estuaries, but they have been found in the ocean and freshwater spots occasionally. The typical habitat of these crocs, otherwise known as croc country, starts just south of Gladstone, by the Boyne River, and extends all the way up the remaining east coast of Queensland, though they are sometimes found outside of this habitat.
These crocodiles are massive, opportunistic, and aggressive and have been known to devour big animals, small animals, and even humans from time to time. Attacks on humans are relatively rare, but caution is required if you’re in croc country and the surrounding areas.
The deadliest attack from these crocodiles is known as a death roll, designed to disorientate their prey. They do this by snatching the animal and dragging it into the water, if the animal (or human) puts up a fight, the crocodiles roll their bodies under the water, confusing and scaring them more. This typically causes the animal to lose its breath, become incredibly confused, and stop fighting — making it easier to eat them.
Taipan snake
The taipan snake, specifically the inland taipan, is the most poisonous snake on the planet and happens to be one of the many animals that are native to Australia, residing in the desert sands. A single snake’s venom is powerful enough to kill up to 100 men and they hunt warm-blooded mammals, though usually much smaller prey like rats.
Despite these snakes being the most venomous, they’re not the deadliest, because they rarely come into contact with humans and no human has died of a bite since 1955, thanks to the anti-venom. The scariest thing about these snakes is the speed at which they strike, known to be one of the fastest attacks; the snake can bite you as many as eight times in a single attack.
There is another, more deadly taipan snake in Australia, known as the coastal taipan. The coastal taipan is known as the third most venomous snake worldwide and is particularly deadly in the country because it frequently encounters humans. These snakes are commonly found along the east coast of Australia, stretching from New South Wales to Queensland. They are most active in the early hours of the day, except during hot weather when they prefer to hunt in the evening.
Australian black widow
Otherwise known as the redback spider, the Australian black widow is one of the most venomous spiders in the country and can be found throughout Australia. Although death is unlikely thanks to antivenom, which has been available since the late 1950s, it is extremely painful and very risky if you’re far away from any medical attention.
Only the female spider is venomous and is much larger than the male, almost three times the size. The spiders like to live in warm, sheltered places. It’s rare to encounter a redback spider, because they avoid leaving their webs, and a bite usually only occurs if you end up putting your hand or another part of your body in the web. Still, it’s important to practice caution.
Unique Australian animals
Thanks to the separation of land mass and Australian animals having to adapt to survive, there are some incredibly rare Australian animals. You just have to know where to look to find them.
Wallabies
Wallabies, often mistaken for Australia’s national animal, are essentially smaller versions of kangaroos. They have compact hind legs that aid them in navigating forested areas with ease. Additionally, compared to their counterparts, wallabies are known for their vibrant colors.
You’re likely to see these creatures bounding along the roads outside of the major cities, as well as in Hunter Valley, New South Wales, between the vineyards.
Fun facts about wallabies
- Wallabies were once on the verge of extinction, but they’re no longer on the endangered list thanks to the efforts of local sanctuaries and the government.
- There are close to 30 different species of wallabies throughout Australia, each grouped by their habitat. These include shrub wallabies, rock wallabies, and brush wallabies.
- Larger wallabies are usually more social and travel in ‘mobs’ or groups.
- Wallabies are herbivorous. a typical feast for them could include flowers, moss, and ferns.
Wombats
Wombats are one of the cutest animals you’ll ever see, second only to the quokka in my opinion, and look like tiny little bears with the chubbiest cheeks you’ve ever seen. Cradle Mountain in Tasmania and the Blue Mountains outside of Sydney are where you’re most likely to see these creatures, but it’s unlikely you’ll spot them outside of zoos or wildlife parks; they’re nocturnal.
Fun facts about wombats
- Wombats weigh between 44 and 77 pounds and grow to about 3 feet long.
- They are one of the many marsupials to roam around Australia, so it has a pouch where their young are nurtured. The wombat pouch faces to the rear though, which helps prevent dirt from getting into the pouch as the wombat burrows.
- Their feces are cube-shaped, thanks to the horizontal ridges in their large intestines.
Quokkas
If you want to see the cutest and happiest little animal you’ll ever lay eyes on, head to Rottnest Island in Western Australia and look out for the tiny little macropod called a quokka. Their tiny little doe eyes and teddy bear ears make them adorable, but it’s their happy nature and smiling faces that make them utterly irresistible.
Fun facts about quokkas
- The quokka roams around fearless like it’s just another tourist on a magnificent island. The reason they roam around so carefree is that Rottnest Island isn’t home to any animals that are a predator of the quokka, which means they’ve never learned to fear anything.
- They spend their days eating shrubs, leaves, and various types of grass and strutting their stuff around the island.
It’s important to note that, despite being so cute and approachable, it’s not advised to feed quokkas human food, and occasional bites have happened.
Platypus
I’ll tell you a little secret; for the longest time, I believed that the platypus was a mythical creature. If I’d never seen one myself, I’d be hard-pressed to believe anything else.
They look like something out of a storybook, with brown fur that glistens with the water, a long tail, webbed toes for swimming, and a bill. It’s also venomous and widely considered to be one of the most unusual creatures in the world.
Fun facts about the platypus
- The platypus is a mammal that lays eggs and resembles a combination of an otter and a duck.
- You’re most likely to find the platypus along Australia’s east coast riverbanks as well as in Tasmania if you’re looking for their natural habitat.
- Otherwise, you’ll find them in various sanctuaries like the Taronga Zoo in Sydney, the Koala Sanctuary in Brisbane, and the Healesville Sanctuary near Melbourne.
Endangered animals in Australia
Whether looking at Australian desert animals or Australian rainforest animals, there is a selection of endangered creatures in the country that local governments and organizations are working hard to protect, including these guys:
Long-footed potoroo
This adorable marsupial is mostly found in southeast Victoria and across the New South Wales border and was badly impacted by the bushfires back in 2019 and 2020, which destroyed a variety of its habitats.
The few surviving long-footed potoroos have played a massive role in the recovery of the damaged areas through the fungi spores dispersed in their droppings, which help to re-establish plant life in the damaged areas.
Timbering and different predators also play a role in the dwindling numbers of the long-footed potoroo, of which there are estimated to be only around 2,500 left in the wild.
Greater glider
The greater glider is a nocturnal mammal with soft bushy ears and a toy-like tail; it traverses the forest canopy across New South Wales, Queensland, and Victoria during the evening and makes its home in hollowed trees during the daytime.
Again, the bushfires, some more recent than 2020, have all but demolished the creatures’ habitats, and in the last 20 years, there has been an 80% drop in population as a direct result of logging. The greater glider was added to Australia’s list of endangered animals in 2022.
Numbat
The numbat, also referred to as a banded anteater or walpurti, feeds exclusively on termites and can eat close to 20,000 of them every single day. There are only two naturally occurring populations left in Australia, found in the southwestern part of Western Australia.
In contrast, various populations have been introduced into South Australia and New South Wales. It’s estimated that there are only less than 1,000 numbats left in the country, and the drop in their population is largely due to habitat loss, land-clearing efforts, and predation. There has been a 99% drop in the population of the numbat since the 1970s.
Famous Australian animals
Australia is home to some of the most unique animals in the world, but there are a select few that the country is best known for, here is a couple of them.
Kangaroo
The kangaroo is the national animal of Australia and possibly the most famous animal in the country. There are a variety of types of kangaroos in Australia, including red kangaroos, western grey kangaroos, eastern grey kangaroos, black wallaroos, and antilopine kangaroos. They are the world’s largest marsupials, with the biggest ones weighing close to 200 pounds and standing almost seven feet tall.
You’ll find kangaroos all over the country, but a few of the best places to check them out include Murramarang National Park along the south coast of New South Wales, Bonorong Wildlife Sanctuary in Tasmania, and Currumbin Wildlife Sanctuary on Queensland’s Gold Coast.
Koala
The koala is one of the most iconic animals in Australia, and unbeknownst to many, are marsupials rather than bears as the common international name might suggest. You’ll find koalas in the eucalyptus forests of Eastern Australia, and fully grown koalas can consume as much as two pounds of eucalyptus leaves in a single day.
They won’t eat anything else and are some of the fussiest eaters around Unfortunately, koalas are on the endangered list because of their loss of habitat, which is largely due to land clearing, bushfires, and droughts.
Rather than visiting them in their natural habitat, there are various sanctuaries around the country you can visit to have a koala experience, such as Lone Pine Koala Sanctuary in Brisbane, Currumbin Wildlife Sanctuary along the Gold Coast, and Kangaroo Island Wildlife Park in South Australia.
Tasmanian devil
The Tasmanian devil is one of the few and largest surviving carnivorous marsupials in the world. Although they used to be found all over Australia, the subsequent destruction of their natural habitats throughout the country has confined them to the state of Tasmania, where they originate from.
A few fun facts about the Tasmanian devil include having a jaw so powerful it can crush human bones, and they have one of the loudest screams, which once convinced European settlers that they were surrounded by demons in the wilderness. They also store fat in their tails, a fat tail is a sign of a well-fed, healthy devil.
Tasmanian Devil Conservation Park in Taranna, Tasman Peninsula, is one of the best places to visit if you want to have an encounter with a Tasmanian devil.
