A woman remains in an induced coma after a serious incident during the Rottnest Channel Swim at the weekend.

The 47-year-old woman suffered a “serious health incident” while swimming in the event on Saturday morning.

It’s understood the woman was still in the water, near the finish line, when she first received medical attention, before she was brought ashore by a rescue boat.

Medical complications while being treated on land meant she had to be airlifted to Fiona Stanley Hospital, where she was put in an induced coma.

She is in a critical but stable condition.

“We have been in regular contact with the family and continue to offer our support,” Rottnest Channel Swim Association president Iain McCarrey told PerthNow.

“The family has asked I also thank the rapid and exceptional response of the medical teams both at the event – many of whom are volunteers – and in hospital.”
