NSW man dead after truck rollover

A 61-year-old man has died in a truck rollover in central western NSW.

The truckie was driving a load of heavy mining equipment when he crossed onto the wrong side of the road and rolled about 7.45pm on Sunday, south of Cobar.

He died at the scene and police are investigating whether fatigue or a medical episode was the cause.

The crash followed another fatality on Sunday when a NSW man's car hit a fence after it left the road at Redhead, a Lake Macquarie suburb.

Police believe the 57-year-old driver may have suffered a medical episode.

He was found unconscious and died a short time later.
