Six people were treated by paramedics in total, according to Queensland Ambulance Service.

Two died at the scene and three were rushed to hospital with critical injuries.

Another person, a woman, was taken to hospital in a serious condition.

Paramedic Kevin Morgan said the crash is believed to have been caused by a head-on collision between two of the cars, before the other was unable to avoid the carnage.

He indicated there were hazardous driving conditions.

“The road was wet and there was a little bit of fog around at the time when we arrived at the scene,” Morgan said.

He said the scene was “quite confronting, certainly given the amount of people trapped in the vehicles”.
