A teenager is in a stable condition after collapsing in shallow water at Noosa Main Beach at 3.32pm on Sunday 1 September.
Noosa lifeguard supervisor Rowan Simpson said the girl was playing in the shallow water before collapsing, which is when lifeguards quickly spotted her and began performing CPR.
A Queensland Ambulance Service spokesperson confirmed the girl was airlifted by LifeFlight to the Sunshine Coast University Hospital in a life-threatening condition on Sunday, following a medical event which occurred on the beach off Hastings Street.
QAS media said the incident appears to not be a drowning, as previously reported in the media.
