Marine Stingers

At certain times of the year, jellyfish, commonly called marine stingers, can affect the coastal waters of North Queensland.

Most jellyfish are harmless to man, however certain varieties may cause a serious reaction. Incidents involving serious marine stings in this area are extremely rare. 

The box jellyfish is found along the coastline during the summer months (November to June). 

The box jellyfish is a coastal species and is not found out on the reef, but they can sometimes be found around islands close to the mainland.

Visitors wishing to swim during this period should only do so in protective swimming enclosures or wear protective clothing.

Other stingers that are sometimes encountered on the reef include the irukandji and blue bottle. 

Both can cause a nasty sting, Vinegar can used on both box jellyfish and irukandji stings but not on blue bottle stings.  For blue bottles use cold water and ice.

Lycra suits and wet suits are available on all reef trips to protect guests from the sun and to reduce the possibility of stings & irritations.

Jellyfish at the reef are dependant on the weather conditions and all reef operators will take appropriate steps to ensure your protection if they believe conditions are such that there is a possibility of encountering these creatures.
