Stingers , or Box jellyfish, do not affect the Great Barrier Reef Stingers are a very dangerous jellyfish. They have long tentacles and have killed people before. They aren't overly energetic animals and have not caused any problems around the reef and islands but occur mainly around the rivers, creeks and beaches north of around Bundaberg. The stinger season is from around November to May. During this time you need to swim inside the stinger enclosures at the beaches or wear a stinger suit.
