Travellers in northern Queensland, Northern Territory, or northern Western Australia should be aware of the risk of fatal stings from the Box Jellyfish if swimming in the ocean between October and May. They are very hard to detect and can be found in very shallow water. Stings from these jellyfish are 'excruciating' and often fatal. Vinegar applied immediately to adhering tentacles will lessen the amount of venom injected, but immediate medical assistance will be required. The danger season varies by location. In general the jellyfish are found close to shore, as they breed in the estuaries. They are not generally found out on the Great Barrier Reef, and many people swim on the reef without taking any precautions. Seek out reliable local information. Some locals at the beach can be cavalier to the risks.
Irukandji are another species of tiny (fingernail sized) jellyfish that inhabit the waters off Northern Australia and the surrounding Indo-Pacific islands. They are also very hard to see, and can be dangerous, although bites are rare. Unlike the box jellyfish they are found out on the reef. The initial bite can go unnoticed. There is debate as to whether they can be fatal, but they certainly can place a victim in hospital, and cause extreme pain lasting days. If you have nausea or shooting pains not long after emerging from the water seek medical treatment.
A "stinger-suit" that is resistant to jellyfish stings costs around $100 or can be hired for around $20 a week.
