A woman and seven-year-old boy are dead after a car rolled off a rural road and hit a tree in south-west Queensland.
Emergency services were called to Chinchilla Wondai Road, 5km from the rural town of Chinchilla, at 4:10pm on Wednesday.
Queensland Fire Department said two crews found a grey Mitsubishi Pajero that had crashed and three occupants needed to be cut free from the wreck.
The driver of the vehicle, a 30-year-old Elimbah woman, sustained serious injuries and was treated by paramedics but died at the scene.
Two other passengers, a seven-year-old boy and nine-year-old girl, were airlifted to Chinchilla Hospital, and the boy was declared dead a short time later.
The nine-year-old girl remained in a serious but stable condition, Queensland Police said.
Officers from the forensic crash unit have launched an investigation into the circumstances of the incident.
