The family were travelling along Beaudesert Boonah Road about 2pm when the car broke through a road barrier, rolled down an embankment and flipped on its roof into Wyralong Dam. Inspector McDonald said the two adults extracted themselves and some of the children from the car. “Unfortunately, those two children (who died) were trapped in the vehicle longer than the other occupants,” he said. “My grandson, partner and children were in a tragic car accident today … two children didn’t survive and a third child (is) in a critical condition. Inspector McDonald said the family, from Pratten near Warwick, were travelling home from Pimpama on the Gold Coast.
