Reported rise in deadly stingers - Mackay Daily Mercury

Carukia barnesi (the Irukandji) is a small jellyfish (~2cm diameter bell) whose sting causes an unusual and dramatic syndrome. Unlike Chironex fleckeri, Irukandji are found mostly in the deeper waters of the reefs in northern Australia, especially north Queensland. Although they may be swept inshore by prevailing currents. Divers and snorkellers are particularly at risk. Stings have been recorded from Childers to Broome, and a similar syndrome has been described elsewhere in the Pacific. Many people have been affected, including several hundred in north Queensland in the summer of 1991/92 and 2001/02.
