Woman Killed After Being Hit By A School Bus

A pedestrian has died after being hit by a school bus full of "extremely distressed" students in the NSW Hunter Region.

Emergency services were called to an intersection in Adamstown at about 3.30pm on Tuesday after reports a woman had been hit by a bus.

Paramedics treated the woman, believed to be in her 30s, at the scene but she died a short time later, NSW Police said in a statement.

Several other cars were also involved in the multi-vehicle crash at the intersection of Brunker and Mandalong Roads, but there are no reports of other injuries, police said.

About 17 school students were on the bus at the time of the crash.

NSW Ambulance Inspector Joel De Zuna said it was a traumatic scene.

"Paramedics did absolutely everything they could to try and save the woman, but there was nothing further they could do," he said.

"We did assess quite a few children at the scene and understandably, they are extremely distressed."

The male bus driver was taken to John Hunter Hospital for mandatory testing.
