Two children have died, a toddler in critical condition and the parents injured when a car crashed into the water at the Wyaralong Dam, near Beaudesert in south-east Queensland yesterday.

Queensland Police Inspector Douglas Mcdonald said the family was in a Land Rover Discovery that crossed unto the wrong side of the road, broke through a road barrier, rolled down an embankment to end up on its roof in the dam.

Passers-by that happened to be two off-duty doctors and a critical care paramedic played a significant role in helping to rescue the occupants and making sure the situation didn’t get worse, Inspector Mcdonald said.
