We're up to 10 Fraser Island area irukandji stings (all requiring hospitalisation, I think) this summer holiday.
As I said a few posts back, if this keeps spreading south, it's a real worry for summer tourism.
If I were the State government, I would be putting plenty of money into research on the matter. As the Guardian's report on the 9th sting indicated, it is difficult to be 100% certain that it is irukandji or a jellyfish in the same family. More needs to be known before any hit further south and the really busy beach areas.
