UPDATE: 10.45AM: The female Warwick State High School student injured yesterday in a crash at Braeside is in a stable condition this morning in Brisbane's Princess Alexandra Hospital.
Chloe McVeigh, 17, is reported to be "doing well", after sustaining serious head and pelvic injuries when her vehicle was struck from the rear by a Crisps coach carrying 47 Assumption College students.
Her 13 year old brother Fraser, who was in the rear seat of the car, is likewise in a stable condition in Warwick Hospital today.
Speaking from Brisbane Chloe's father George McVeigh said his daughter, who was flown to Brisbane last night in the State Government Rescue 500 helicopter, had regained consciousness this morning and things were "looking positive".
He said Chloe had been in intensive care overnight and the family would await the results of further tests later this morning.
He also said Fraser was doing well in Warwick Hospital, where he stayed overnight for observation, and had a broken thumb and bruising.
A 17 year old male student in the passenger seat of Chloe's vehicle was treated at the scene for an ear injury.
The students were all returning from the Border District athletics carnival in Stanthorpe when the crash happened at about 2.45pm, with Braeside roughly halfway between Warwick and Stanthorpe.
Chloe and Fraser both had to be freed from the vehicle by firefighters using the jaws of life.
None of the Assumption College students on the bus was injured, but were badly shaken and were met by parents and a counsellor on their return to Warwick late yesterday on another bus.
The Crisps driver was likewise uninjured but shaken, and was the first to go to the aid of the teens in the car.
Investigations into the cause of the accident by police forensic crash officers will continue today.
The father of a Warwick High student who was following one of two other buses carrying those students, travelling behind the Assumption bus, was among those first on the distressing scene.
He was last night full of praise for teachers from both schools who helped stabilise Chloe McVeigh.
"They were tremendous, they held her head and kept her calm while they waited for the ambulance," he said.
"She was vocal and was able to move her legs, but she was in a lot of pain.
"All of the kids from both schools were just in shock - the Warwick High kids who were travelling behind recognised the car.
"They was lucky it was a newer-model car and took the impact pretty well; it could have been a lot worse."
The mother of one of the 47 Assumption College students on the bus last night said the mood of the students on their return home was "sombre".
"As a parent your heart just goes out to the parents of the students who were in that car," she said.
"This is such a small community and the Assumption kids knew those who were in the car and were really shaken up.
"You would never expect your children to go off to a sporting carnival and come back in an ambulance.
The New England Highway was reduced to one lane around the accident scene for several hours while the wreckage was cleared.
