Death By Jellyfish

Death By Jellyfish

Sharks, Jellyfish, and Dangerous Sea Creatures In Australia.

Cheap vacations and vacation packages to Australia can be the holiday of a lifetime, or can end in misery and even death. Unsuspecting tourists are stung and attacked every day by potentially life threatening insects, spiders, snakes, sharks and jellyfish in Australia.

Shark attacks along the Australian coast are regularly reported in the worlds press, whilst death by jellyfish stings are not, even though they regularly cause death.

Vacations in Australia can be potentially dangerous and result in death. Australia has the most venomous and poisonous spiders, snakes, insects and sea creatures in the world. Dangerous sea creatures such as jellyfish are abundant in the land of plenty. Although attacks are in the low percentage compared to the amount of visitors Australia receives, visitors still die or need life saving surgery to save their lives after being attacked.

Visiting Australia is an absolutely fantastic experience, just make sure you come home in one piece and with as few bites and stings as possible.

Box Jellyfish ( Sea Wasp )

A sting from a Box Jellyfish can stop your heart within three minutes. The toxins in the Box Jellyfish are so potent, that it causes more deaths in Australia than snakes, sharks and alligators. It has a square-ish body with tentacles growing to 80 cm in length, and inhabits the North Eastern waters of Australia.

The Box Jelly fish makes its' usual home on the Great Barrier Reef, although they have been sighted as various times around the whole of Australia.

Many Australian beaches have anti Jellyfish nets to protect bathers. The top speed of the Box Jellyfish has been recorded at six meters per minute. Unlike other jelly fish, the Box Jelly fish has proper eyes, with retinas, lenses and corneas, so it can watch you as it stings you.

In late 2010, a young girl out swimming one fine day, was stung by a Box Jellyfish, and lived, it was called a medical miracle. These creatures of the deep kill 60 people just in the Philippines alone every year.

The worst months for Box Jelly fish in Australia are May and October. Four days after a full moon, the jellyfish come close to shore to spawn, so be warned if on vacation Australia, and there has been a full moon, stay on land, go miniature golfing or something.

If you get stung by one of these, do not get someone to pee on you, it has never been proved to reduce the toxins which are released into the bloodstream. The tentacles will still be stinging you if the animal is dead, even if the tentacle has been removed from the body of the jelly fish.

Vinegar is meant to help, but not many people have vinegar on a beach. If you are stung, get out of the water screaming and shouting, get attention by the lifeguards as quickly as possible, they will be able to help by administering a drug called Chironex. This is your Australian vacation, always be careful.

Irukandji Jellyfish

Found in Northern Australia, the deadly Irukandji jelly fish is usually only 1cm wide. Over recent years and due to climate change, this deadly jelly fish has been found near the British Isles and Florida. The Irukandji jellyfish attaches itself to a victim using the stingers cause a slightly delayed reaction to the initial pain.

Once the victim tears away the jellyfish from their skin, the stingers become detached from the jellyfishes tentacles and stay inside the victim, releasing deadly venom. They can also fire stingers through the water at prey.

Irukandji Syndrome is caused by the sting from the jellyfish. Victims will begin to feel nauseous, pains and muscle cramps will rack the body, and pain will begin in the back and kidneys. Headaches are common as well as sweating and vomiting.

The heart rate will increase rapidly as will blood pressure. The skin will seem to be burning and the victim may suffer restlessness and psychological phenomena similar to thoughts of impending doom and depression.

Vacations in Australia can easily be ruined by this creature. If a person thinks they may have been stung by anything around the coast of Australia, seek medical attention immediately, your life may depend on it.

The Blue Ringed Octopus

The tiny Blue Ringed octopus has destroyed many families whilst on vacation or holiday in Australia.This eight tentacled creature is only 20 cm in diameter, with its tentacles spread. It is found in most warm waters around the world and also lives on the Great Barrier Reef. Its diet is usually smaller fish or any bigger fish that has been wounded, and like any Octopus, if it loses a tentacle, it will grow one back.

Some groups of people, will eat these raw, they are extremely venomous, and can kill, so they just pop one into their mouths and swallow them alive and whole. They have to ensure that the stinging tentacles are fully wrapped up, or they would sting whoever's mouth they are in or the throat on the way down, causing asphyxiation and virtually instant death.

The Blue Ringed Ocotpus has recently been making headlines across the globe. Don't be fooled by it's beauty, it is known as the worlds most venomous marine creature. When agitated, the 50-60 blue rings over its' body will appear to pulsate.


Once stung, the venom will paralyze the respiratory muscles within minutes, and can totally paralyze the whole body within 5-10 minutes. This is only temporary and may last for up to two hours. It is essential for the stung person to receive artificial respiration as soon as possible to avoid death. If the stung person appears non-responsive, do not stop with the artificial respiration.

The victims can be fully aware of their surroundings but totally unable to move. Whilst on vacation to Australia, always try to swim with someone else, or have them nearby just in case of accidents.





This spikey little critter gets its name from the way it can camouflage itself against the rocks on the sea bottom or on the Great Barrier Reef. It is usually found in shallow waters and is between a red and a brown color. Its toxic venom is delivered via thirteen spines on its back, and if you stand on one, you could be dead within two hours.

The Stonefish does not attack anybody, its main diet is shrimp, the spikes are only for defense against other predators. Many people on holiday in Australia have been injected with the toxin of the Stonefish because they have inadvertently stood on one whilst swimming in the shallow waters, but many boat crews for day trippers carry anti-venom serum, just in case. Don't panic, just be careful.

Salt Water Crocodiles

Now we are getting to the animals with teeth. Salt water crocodiles can grow up to seven meters in length, and are also found in Florida among other places. These are again found in Northern Australia, but not only in the sea, they are found over eighty kilometres inland as well, and with a mouth larger than the average mother-in-law, can take an arm or leg off with one bite.

These Crocodiles are a protected species in Australia, and can be found in the shallows of the sea and on the beaches, and being the worlds largest reptile, if you do see one, run. You can inform the local authorities and they will come and remove it, do not try and remove it yourself, it is not an animal that you can just put a leash on and take it for a walk.

Just an additional note, these crocodiles can lay up to 60 eggs each year, and can be very protective of them. Many people on vacation in Australia have been attacked whilst trying to get close and take photographs. Vacations or holidays are excellent and relaxing, do not tempt fate by putting yourself in needless danger.

Don't let this take a bite out of your vacation

The Great White Shark

The Great White shark can be found on all coast lines of Australia, and has been known to attack surfers in the early hours of the morning. This big fish can grow up to five meters in length and can weigh nearly 1,400 kilograms, and this killing machine has nearly 3000 teeth at any one time, no wonder people fear it.

The Great White, which is actually grey on top and white underneath, can smell a little bit of blood in the water a few miles away, and this is one way it will track its intended victims, so maybe if you have a small cut you should stay out of the water. Being a shark, and the Great White is a member of the Mackerel Shark family, it needs to constantly swim, or it will sink, literally just fall to the ocean bed.

Their main diet is, well, anything really, they eat dead fish, live fish, men, women, whales or anything that swims. They have been known to attack killer whales and swim away, waiting for their prey to die before coming back to dine on them.

The female Great White shark is usually larger than the male, and are mainly solitary predators, but have been known to swim and hunt in groups. This is the ultimate marine life killing machine, there are several attacks or sightings of the Great White every year in Australia, if you are swimming and you see a fin in the water, swim as fast as you can towards the beach, do not stop swimming, even if you have gone over the beach and across a road, don't stop and never look back.

Tours in Australia are easily available to view all the sea life and land mammals, some of which can scare the pants off of you whist on vacation to Australia.

I should mention that there are no alligators in Australia, only crocodiles.

Hi, I live in Far North Queensland, so I'm pretty used to all these nasties. I have to say, they hardly affect us, we don't swim in the sea from October to May ( stinger season), we have pools for that time of year. In your article you say May AND October, this is incorrect. Many tourists do swim, the stinger nets are always full despite not being 100% effective. Most locals don't swim in stinger season, unless wearing a full body stinger suit . Thanks for helping to raise awareness, it frustrates me terribly that tourists continue to take these risks, particularly with their children. I should add that the tropical sun is, in my opinion, far more dangerous than all of the above creatures.

I've lived in Australia my entire life, swum many times in our oceans and walked many times in the bush and NEVER been affected or known anyone affected by any of these creatures, australian or tourist. Yes, there are many dangerous creatures in Australia but this article makes it sound like there is something lurking behind every corner which is not true whatsoever. It is important to be informed but also important to know how incredibly RARE all these things are.
