Deadly Irukandji Jellyfish are drifting further south along Queensland's coastline, however tourism chiefs aren't worried about the risk to the state's famous beaches.
Toxicologist professor Jamie Seymour has "little doubt" Irukandji will keep moving down to the Gold and Sunshine Coasts after a stinger was found at Fraser Island on Sunday.
A boy was already stung on Mooloolaba Beach on the Sunshine Coast 12 months ago.
"It would shut beaches. It would collapse tourism," the director of the Tropical Australian Venom Research Unit at James Cook University told AAP on Wednesday.
Mr Seymour cited warmer sea temperatures as the reason Irukandji could become a regular occurrence at Mooloolaba, and even as far south as Coolangatta on the Gold Coast.
However, Queensland Tourism Industry's chief executive officer Daniel Gschwind dismissed Mr Seymour's concerns saying there is no need for panic.
"We want people to have a great time here and go away healthy. We are concerned about any potential risk but there is no need to be alarmed at this point," Mr Gschwind told AAP.
Mr Gschwind said collaborations with Surf Life Saving Queensland allows information on risks to be communicated quickly to swimmers.
"To speak about some sort of migration is misleading or premature," he said.
Prof Seymor believes more forward-planning could be done on the issue and is "sick of" warning of the risk of the highly venomous species.
"How many more people need to get stung before it's realised it is not just a one-off?" he asked.
"Be proactive, don't wait until it becomes a larger problem. Throw money at it now."
The Irukandji jellyfish caught on the western side of Queensland's Fraser Island on Sunday prompted a warning for swimmers to stay out of the water.
There were 10 suspected Irukandji stings on the western side of Fraser Island between December 22, 2016, and January 5 last year.
