A man is in a critical condition and 11 others were also injured after a competition car did a burnout at a drag racing event in Alice Springs, sending burning fuel spraying over crowds of onlookers.
Twelve people were burned when the car at the Red CentreNATS event on Sunday sent the lit fuel flying during the burnout with vision showing flames being thrown out over fans.
The Royal Flying Doctor Service airlifted a man, 48, and his 19-year-old son, both from NSW, to Adelaide, where one of the men is in a critical condition at the Royal Adelaide Hospital.
Both men have suffered burns to 20 per cent of their bodies, including the face and arms.
Two other people have been admitted to the hospital and remain in a stable condition.
Organisers immediately shut the event after the fire and police are investigating.
"This is a distressing situation, however all patients are receiving the care they need," a spokesperson said in a statement.
