Serious envenomation of an adult pregnant woman by a box-jellyfish (Chironex flecteri) in North Queensland is reported. Quick thinking and resuscitation by bystanders which was followed by early hospital treatment resulted in a successful outcome both for mother and for fetus. ⋯ Avoidance of fetal stings in the future is possible by simple preventive measures. The role of the Surf Life Saving Association of Australia in the prevention and treatment of such problems is highlighted, and, as a result of recent research, possible changes in the management of box-jellyfish envenomations are predicted.

Laboratory tests indicate that methylated spirits, widely espoused as a first-aid treatment for jellyfish stings, causes massive discharge of nematocysts in living tentacles of the box-jellyfish, Chironex fleckeri. This action, together with demonstrated hazards of flammability and intoxication, casts doubt on this substance as a treatment for Chironex stings. ⋯ Weak solutions of acetic acid, as well as commerical vinegar, were found to inactivate the penetrating nematocysts of Chironex rapidly and completely. Most other substances tested proved less effective, and some actually stimulated the firing of nematocysts.
