If you get a big box jellyfish sting the pain is immediate and there is no pain relief. The most important things is to keep the heart pumping. An irukanji sting is slightly different — there will usually be about a 20 minute delay before the symptoms of vomiting, headaches, sweating, rapid heart rate and high blood pressure kick in.
The Australian box jellyfish season now runs from November through to July in Cairns, whereas it previously only lasted until May.
