UPDATE: Police are appealing for witnesses with information about a small white vehicle driving erratically on the Bruce Hwy in the vicinity of a crash south of Bauple on Sunday morning.

The police said preliminary information suggested the vehicle, possibly a hatch, had been travelling northbound in the area where the crash happened shortly before 7am.

Investigators would like to talk to anyone who may have information in relation to this vehicle and are asking them to phone Crime Stoppers on 1800 333 000.

Police said it was believed a southbound four-wheel drive swerved suddenly resulting in a loss of control with the vehicle rolling several times before righting itself and crashing into a fence and nearby cane fields, then returning to the highway and coming to a stop.

Two women, both aged 30, were trapped for a period of time in their four-wheel drive.

The driver, from Mount Cotton, was flown to the Royal Brisbane and Women's Hospital with head injures.

Her passenger, a woman from Emerald, was transported to Gympie Hospital with leg injuries.

The highway was closed for several hours before reopening shortly before 11am

EARLIER: The female driver of a four-wheel drive that rolled on the highway south of Bauple has told emergency workers she swerved to avoid an oncoming car.

RACQ CareFlight Rescue was called to the crash, which closed the Bruce Hwy for about four hours, about 7.30am on Sunday.

A CareFlight Rescue spokeswoman said the 23-year-old driver, who suffered multi-trauma injuries, "told the crew she swerved to avoid an oncoming car".

"She was stabilised at the scene by the helicopter's doctor and intensive care fight paramedic," the CareFlight representative said.

The woman was flown to the Royal Brisbane and Women's Hospital in a serious but stable condition.

The CareFlight spokeswoman said the female passenger, 30, suffered minor injuries and was taken by road ambulance to Gympie Hospital.

"Investigations into the crash are continuing, but it's believed the driver may have hit her head and that the vehicle continued out of control for some distance, before rolling and coming to a stop," she said.

The highway reopened about 11am.
