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).

The eastern brown snake is widespread throughout eastern Australia, from northern Queensland to South Australia, with isolated populations occurring in central and western parts of the Northern Territory. This medium-sized snake, with a slender to moderate build and a smallish head barely distinct from the neck might not look as intimidating as other snakes but its bite is one of the deadliest in the world since it’s considered the second-most poisonous animal in the world.

According to the Australian Shark Attack File, kept by researchers at Sydney’s Taronga Conservation Society, there have been 1,003 shark attacks in Australia since records started being kept in 1791, and 232 of them have been fatal. All told, about one-quarter of shark attacks are fatal, with the majority of them coming from the meanest shark of all: the bull shark.

Irukandji jellyfish are tiny but extremely venomous jellyfish that inhabit the waters off Australia. They are able to fire their stingers into their victim, causing symptoms collectively known as Irukandji syndrome. An interesting thing about the Irukandji jellyfish is that it also has stingers on its belly whereas most jellyfish have stingers only on their tentacles. Biologists have yet to discover the purpose behind this unique characteristic.

Even though honeybees are not considered some of the most deadly species in general, it looks like in Australia they are responsible for one to two deaths annually. It’s estimated that up 3% of the people in Australia are allergic to apitoxin which is the venom produced by honey bees.


Box jellyfish

The Indo-Pacific or Australian box jellyfish is claimed to be the most venomous marine animal known to man and its sting is often fatal. This extremely poisonous marine stinger frequents Australia’s northern oceans all year round. However, it is particularly dangerous during the wet season, from about November to April.
