NSW Ambulance Acting Inspector Nathan O'Brien said "no words could describe the scene that we were faced this evening".
"Going to a road accident when we know there are children involved is always difficult for first responders," he said.
"Multiple patients with serious injuries can create a very challenging environment for paramedic crews.
"It is our responsibility to do everything we can to provide life-saving treatment.
"Despite the best effort from paramedics sadly one patient died at the scene."
Fire and Rescue NSW and other emergency services were also at the scene.
Motorists were advised to avoid the area and use an alternate route as both directions of the motorway were closed.
