Dangerous, and in the tropical north only (see the map). The stinger season typically runs November to May, but stingers can be in the water all year in tropical Queensland. A severe box jellyfish sting can stop a person breathing and cause cardiac arrest. Irukandji are small and usually not seen. Their sting is minor at first, then severe pain, vomiting and sweating can start 5 to 40 minutes later.

  • In stinger season, swim only at a patrolled beach under the guidance of lifesavers.
  • Stinger nets help against box jellyfish but are not reliably effective against Irukandji.
  • If stung: get the person out of the water, call 000, pour vinegar over the sting for at least 30 seconds, and start CPR if they are not breathing.
  • For any tropical jellyfish sting, keep the person out of the water and watched for 45 minutes.
