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 common lionfish is a tropical species found widely throughout the Indo-Pacific region. In Australia it’s found in southwestern Western Australia, around the north of the country and in the south to the southern coast of New South Wales. It’s considered to be an extremely venomous fish. The venom found in the needle-sharp dorsal, pelvic and anal fins, though not necessarily deadly to an otherwise healthy human being, will cause an immense amount of localized pain, swelling and, in some rare cases, death if not treated properly.

Though rarely deadly, a Bluebottle sting can be dangerous to children, elderly people, people who suffer from asthma and people with allergies as it can cause fever, shock, and respiratory distress. Medical attention is sometimes necessary, especially if there is: intense and persisting pain, an extreme reaction, a rash that worsens, a feeling of overall illness, a red streak developing between swollen lymph nodes and the sting, or if either area becomes red, warm and tender.

The highly venomous yellow-bellied sea snake is the most widely distributed snake in the world, as well as the most aquatic, never having to settle on land or the seafloor its entire pelagic life. It is a species of sea snake found in tropical ocean waters, and is particularly famous in Australia where it spreads terror every summer to swimmers and surfers alike, since its bite has been usually deadly in most of the cases.

The great white shark is one of the most famous and feared species of shark not just in Australia but anywhere in the world near the sea. Though responsible for fewer attacks than other members of its family such as the bull shark and tiger shark, the great white has the reputation of having one of the meanest bites in the shark world thanks to it’s incredible set of razor sharp teeth which can easily tear flesh apart.

Tiger snake

Most Australians know of tiger snakes and are aware of their fearsome reputation, though few will ever encounter one. Unfortunately, this species is much maligned because of its aggressive nature and toxic venom; however, the tiger snake should be recognized as a great survivor, superbly adapted to some of the most inhospitable environments in Australia.
