A 40-YEAR-OLD woman has been transported to Bundaberg Hospital with a suspected Irukandji jellyfish sting after swimming at Agnes Water.
The Mackay tourist remains in hospital in a stable condition after arriving by ambulance at about 2pm today.
Bundaberg Queensland Ambulance Service senior operations supervisor Martin Kelly said an advanced care paramedic was tasked to meet the Agnes Water ambulance on its way to Bundaberg.
Mr Kelly said the way the woman presented was consistent with an Irukandji sting.
"It starts off with not too much pain then becomes progressively worse," he said.
He said paramedics administered a significant amount of pain relief as they transported the woman.
Mr Kelly said the incident highlighted the importance of swimming at a patrolled beach.
"The life savers were the first to give first aid until the ambulance arrived."
