The woman has suspected neck injuries, and was unconscious for an unknown time after the crash.
She was airlifted back to Toowoomba Base Hospital in a stable condition.
The CareFlight crew skirted around a series of storm cells, to return to Toowoomba.
“It was fairly mild when we took off, but another cell developed to our left and we went around to Dalby to come in behind it,” he said.
“The temperature outside the helicopter at 5,000 feet was 30 degrees.”
