I am planning a holiday to north Queensland but will only be snorkling and diving offshore – do I have to worry about jellyfish stings ?
Yes ! Although the most dangerous jellyfish is the Chironex-type box jellyfish (it can kill in minutes) that is only usually found very close to shore, you can still get stung by nasty jellyfish whilst snorkling and diving. The biggest concern is the Irukandji jellyfish. Many serious cases of this type of jellyfish sting occur whilst swimming off the offshore islands and on reefs well offshore. However >90% of these cases could have been prevented by the use of stinger suits (usually available for hire). So to avoid jellyfish stings swim in the winter months and wear a stinger suit.
