Another swimmer has suffered a suspected irukandji jellyfish sting in waters off Queensland's Fraser Island.

The teenage girl was airlifted to hospital for treatment late Wednesday night after being stung on the leg.

She was initially treated by Queensland Ambulance Service paramedics at Orchid Beach before being flown to Bundaberg Hospital in a stable condition.

The incident is the 10th suspected irukandji sting on the western side of Fraser Island since December 22.

Ten people have been treated for irukandji stings on Fraser Island.
