25 Most Dangerous Animals In Australia You Don’t Want To Mess With

Human habitation of the Australian continent is estimated to have begun between 42,000 and 48,000 years ago, possibly with the migration of people by land bridges and short sea-crossings from what is now Southeast Asia. It would be discovered by the Europeans which would then become a penal colony for British criminals around 1788. Since then Australia has gone through major socioeconomic changes and is now one of the wealthiest countries in the world. What hasn’t changed much is the fact that Australia hosts some of the world’s most dangerous creatures. It’s true that when it comes to creepy, deadly, and poisonous living organisms Australia is up there with the likes of Africa. However, and despite the fact that Australia has so many of the world’s most venomous and toxic “beasts”, according to the country’s death statistics, the most dangerous animals to humans are — believe it or not — horses (due to accidents while riding them). Nevertheless, sharks, spiders, and snakes still get the majority of bad press and today we are going to share with you 25 of the most dangerous animals in Australia (which might be wise to avoid).

Reef stonefish

The reef stonefish’s incredible ability for camouflage is ridiculous! Often looking like an encrusted rock or lump of coral, the species is widely distributed throughout tropical, marine waters of the Indo-Pacific region. It has stout dorsal fin spines that can inject an extremely poisonous venom capable of killing a human if it goes untreated.



Redback spider

Redback spiders are found throughout Australia and are common in disturbed and urban areas. It belongs to the Theridiidae family, which is found worldwide. The notorious black widow spider of the United States is a close relative of the redback, and only differs in appearance by the absence of a red dorsal stripe.


Inland taipan

Often cited as the world’s most venomous snake, the inland taipan is far from the most dangerous. Unlike its congener, the common and fiery-tempered coastal taipan, this shy serpent is relatively placid and rarely encountered in its remote, semi-arid homeland. Make no mistake, though, if you get bitten by one your life is definitely in danger!


Highland copperhead

Copperheads have managed to eke out an existence in some of the coldest high-rainfall regions of Australia, where most other snakes would perish. Their venom is hemolytic, meaning it destroys the red corpuscles of the blood and releases the hemoglobin into surrounding fluids. Though normally not fatal, their bite is extremely painful and causes significant damage to muscle and bone tissue.


Collett’s snake

One of the most spectacularly colored snakes in Australia, Collett’s snake is a shy and rarely seen inhabitant of Queensland’s black soil plains. However, if you are unlucky enough to be bitten by one you have to rush to the nearest hospital because its poison can kill you pretty quickly.
