Two children died after their car crashed into a dam, trapping them inside.
A family of six was driving down a stretch of road near the Australian city of Brisbane when their vehicle swerved off the road and descended a stone embankment.
A 13-year-old boy and a 4-year-old girl died tragically.
The male driver, 23 years old, and a 33-year-old woman, along with two other children, five weeks and one year old, managed to escape and remained in a stable condition.
According to Queensland Police Inspector Douglas McDonald, the car, a Land Rover Discovery, came to rest on the roof in a semi-submerged position.
He said, “Unfortunately those two children (who died) were trapped in the vehicle longer than the other occupants.
“It took some effort to open a number of doors for the vehicle.”
The policeman went on to say that passers-by performed CPR on the trapped children after they were eventually pulled from the car.
Inspector McDonald described the situation as “truly traumatic” for the emergency responders and others who stopped to help.
He added that it is unclear what caused the crash, but believed there was no alcohol involved, while all occupants were wearing seat belts.
Child seats were in the car.
The family, away from the town of Warwick near Brisbane, was traveling from the Pimpama on the Gold Coast.
Insp McDonald said investigators are investigating whether fatigue led to the crash and although the two adults have been spoken to, no formal talks have yet taken place.
The husband and wife are undergoing surgery for non-life-threatening injuries.
Anyone who may have dashcam footage is asked to contact the police.
