Two children have been stung by suspected irukandji jellyfish within hours of each other in Queensland.
A 10-year-old girl was stung at Cairn's Trinity Beach around 12.30pm on Wednesday, two-and-a-half hours before a 12-year-old boy was taken to Hamilton Island medical centre with a sting to his upper left thigh.
A Queensland Ambulance Service spokeswoman said the boy began developing symptoms around half an hour after leaving water off the island, which is a popular Whitsundays tourism destination.
The incidents come after two people suffered suspected stings in other parts of Cairns on Tuesday, prompting beach closures.
A 58-year-old man was stung by an unknown variety at Stratford but didn't require hospitalisation, while a 46-year-old woman thankfully recovered after what was initially feared to be an irukandji sting at Clifton Beach.
