An emergency operation is underway after a car carrying six people crashed into a Queensland dam.
At least two children are in a critical condition following the Beaudesert Boonah Rouad crash in Wyaralong, southeast Queensland, at about 2pm.
Three rescue helicopters have also been deployed, a Queensland Ambulance Service spokeswoman confirmed.
A police car which was on the way to the scene crashed and rolled shortly afterwards.
The officers involved sustained minor injuries.
Motorists have been warned to find a different route with the road closed in both directions at Wyaralong.
More to come.
