Crocodiles

  • Danger Level: 9/10

Australia is heavily known for its crocodiles. While saltwater crocs can be found in other places, freshwater versions can too. It is only in Australia, however, where you’ll see both. Australia’s freshwater version is not known as a man-eater, mostly due to the size of freshwater crocs. They will bite out of self-defense, however. Australia’s saltwater crocodile is the real killer to look out for. They do not mind attacking any species near them. Crocs have attacked lions, cheetahs, hippos, deer, and more.

While the crocs of Africa are bad, Australia’s crocodiles are heavily notable. This is mostly due to Australian conservationist and television host, Steve Irwin. Nicknamed the “Crocodile Hunter,” he helped us learn more about them and was very effective in several studies on the species. In total, roughly 1,000 people are killed by crocs annually. Many of these happen here, making them one of the deadliest animals in Australia today. However, the best thing to do if you see a croc is to simply run in the opposite direction. Try to not randomly go into marshes or places they are common, to begin with, too.

Eastern Brown Snakes

  • Danger Level: 10/10

Australia certainly has a lot of snakes, and the Eastern Brown Snake is one of the most feared. This is ultimately due to their venom level, which ranks as the second-most of any snake on the planet. Australians see them quite a lot, which is why they are responsible for up to 60% of all snakebites in the nation every year. They tend to be pretty solitary, however. That’s probably why their yearly human bite count is not exactly massive.

People in the bush tend to be the most common to be bitten, as the eastern brown snake usually does not live around human beings. Yet encroachment on environments that these snakes hold has led to more interactions with them. The species is certainly deadly, and that’s due to what their venom is packed with. It has a potency of 5.0mg and filled with neurotoxin, hemotoxin, and mycotoxin. This is why it is capable of killing within 15 to 30 minutes, with a maximum of just 1 hour!

Box Jellyfish

  • Danger Level: 10/10

While Box Jellyfish can be seen in various places, they have been known for their heavy connection to the Australian region for many years. The species is responsible for more serious injuries to humans than sharks, sea snakes, and stingrays combined annually. Plus, they are known for killing up to 50 people per year. How do they accomplish so many injuries and even deaths each year? First, it’s due to traveling in packs where you won’t just see one jellyfish but often several.

Second, they rarely sting just once. When you are attacked with just one swipe of their venomous tentacles, they will send more in rapid succession. They contain what is known as “jellyfish venom,” which is mostly a combination of powerful neurotoxins. It can paralyze people, make it hard to breathe, cause heart problems, cause necrosis, shock, etc. That can make getting to safety after an attack quite hard. Depending on the severity, people can die from a sting or series of them anywhere from a few minutes to a few hours. It’s all dependent on the person ultimately.

Inland Taipan Snakes

  • Danger Level: 10/10

The Inland Taipan Snake is the single most venomous snake on the planet today. Just one bite from this snake is enough to kill 100 full-grown men. The crazy part is that you’d think with so much packed in one bite, they’d be unable to offer lethal doses in other bites. However, the snake has an excellent recovery rate and can offer a severe strike several more times in a row without falling off of lethality.

The venom that the inland taipan possess is filled with neurotoxin, paradoxin, hemotoxin, oxytoxin, myotoxin, and som hyaluronidase enzymes. These add up to make the venom very deadly. Certainly enough to make this snake one of the deadliest animals in Australia. The venom is absorbed by the body quickly and results in human death anywhere between 5 minutes and just under 1 hour. There is an antivenom for it, but that’s if you’re lucky enough to get it in time.
