POLICE have confirmed the three people involved in a serious high impact head-on crash on the Wide Bay Highway yesterday morning are from the Gympie region.

A 33-year-old Kilkivan man who was driving a white Commodore and a 59-year-old Veteran woman who was a passenger in an Isuzu are in the intensive care unit at Brisbane’s Royal Brisbane and Women’s Hospital.

They were choppered there from the crash scene at Lower Wonga on Wednesday afternoon. Their current status is unknown, according to police.

Both people were airlifted after paramedics worked for hours stabilising them for transport in separate helicopters.

The driver of the Isuzu – a 58-year-old man also from Veteran, was taken to the Sunshine Coast University Hospital- his status is also unknown.

Police said yesterday the cars smashed at high impact on a straight stretch of road, near the Lower Wonga power sub station.

The white Commodore caught fire after impact, but a witness was able to put the flames out with a fire extinguisher he had in his car.

An emergency service worker said this saved the life of the driver who was trapped in the front of the car.

Emergency service workers were required to cut the car door off and lift the dash away from the man before paramedics could treat him.

The man suffered critical injuries including head, chest and abdominal injuries, multiple fractures in his lower legs and a compound fracture of his wrist, Gympie ambulance officer in charge Wayne Sachs said at the scene yesterday.

The woman passenger in the Isuzu also suffered critical head and chest injuries, and upper limb fractures.

The driver of that car, who had freed himself before help arrived, suffered bruising, cuts and fractures though his status deteriorated at the scene and he was transported under lights and siren to the Sunshine Coast University Hospital.

Police are now appealing for any witnesses, especially anyone who may have dashcam footage- particularly dashcam footage of the white Commodore near or at the time of the crash.

Inspector Pat Swindells said police would be investigating speed and if substance abuse was involved in the crash.
