Two rescue helicopters were called to Teewah Beach on Saturday night following a single-vehicle rollover.
Paramedics assisted two Brisbane teenagers, after their Toyota LandCruiser crashed.
One of them suffered a suspected head injury and was flown to the Royal Brisbane and Women’s Hospital in a serious but stable condition.
The other sustained facial injuries and was flown to Sunshine Coast University Hospital (SCUH).
The incident is under review.
The accident was among several call-outs for emergency responders overnight.
Paramedics helped a patient who had sustained burns from a fire, transporting them from Valdora to SCUH.
Paramedics also attended a shed fire at Ilkley in the early hours of the morning.
There were no injuries and the Queensland Fire and Emergency Service is reviewing the incident.
