Concerns have been raised about the southbound Irukandji jellyfish as rising global temperatures push the species further south than ever before.
James Cook University Toxicology Professor Jamie Seymor said there is little doubt of the likelihood that the Irukandji will move further south towards the Gold Coast and Sunshine Coast.
Concerns were raised after an Irukandji jellyfish was caught on the western side of Fraser Island on Sunday, prompting warnings for swimmers to stay out of the water.
