Ebony Rich had just dropped her brother to a Christmas lunch on Wednesday at Elimbah when her white Suzuki hatchback was hit from behind by another car on Beerburrum Road, forcing it to leave the road and roll several times.

The 18-year-old suffered serious internal injuries and a head wound and was receiving treatment at the Sunshine Coast University Hospital.

Ebony posted photos of the crash to social media, asking for help to find the driver of the other vehicle.

"My life flashed before my eyes today," she wrote.

"An ignorant human going excessively over the limit in an 80km zone, purposely ran into the back of me causing me to flip multiple times onto the other side of the road."

"He continued to drive very fast and leave me pinned up in a car wreck upside down."

Her father, Max Rich, had been cleaning up after a Christmas breakfast when he received a frantic call from his son informing him of the crash.

"I came into the hospital and I was shaking, I don't even remember where I parked my car," he said.

Mr Rich said Ebony was still traumatised by the incident and needed more scans on her injuries.

"She's got to go in for more X-rays … she's still covered in blood, her head has been stapled together," Mr Rich said.

The driver that hit Ebony overtook several vehicles before rear-ending her Suzuki hatch, according to police. The driver did not stop after the collision.

The car involved was a maroon or red Subaru Impreza hatchback with registration number 373ENZ, though police believe these plates belong to a different vehicle. One plate was left at the scene after the force of the impact knocked it off.

Mr Rich praised the actions of a man travelling in a car behind his daughter, who saw the crash and came to her aid.

"I spoke to a good Samaritan who stopped, he was following her car, the car went into a ditch … missed a big tree, became airborne, rolled twice and landed on its roof," Mr Rich said.

"There was fuel and oil leaking into the car. He had to cut her out of the seatbelt."

Charlie Eaton was one of the first people on the scene and stayed with Ebony until emergency services arrived.

"My only role was to talk to her and keep her calm and to call her parents, keep them calm, and have them on speaker with Ebony until the ambulance arrived," Ms Eaton said.

"The guy who pulled up right before us got Ebony out of her car and just sat down with her … Ebony stayed calm and strong the whole time.

"I hope they catch the man who did it."

Ms Eaton said what she saw was horrific.

"She had much more blood on her [than the photos show]," she said.

"I took the photos to show her parents she is OK."

Mr Rich says he fears what would have happened if his son had still been sitting in the front passenger seat.

"She'd just dropped one of my sons off, and if he was in the passenger seat of the car he would not have survived. The passenger side of the car does not exist," he said.

The Sunshine Coast father has made a public appeal to help track down the driver of the stolen car.

"This parasite who left my daughter in this situation continued on … so the message is out there for everyone to try to find him," Mr Rich said.

"I think he should hand himself into police. I think it would be a less painful way to go about things because there's not a lot of happy people about this.

"I ask every member of the general public to open your eyes and find this person, for Ebony's sake."

Police have confirmed they are investigating the incident.
