A school bus collision has left the Singleton community grieving the loss of nine-year-old Harry Dunn.

He died at the scene after being thrown 10 meters through a side window of the bus.

Among the other seven children injured, was younger brother, Luke Dunn, 7, who was air-lifted to John Hunter Hospital with serious head injuries.

The 54-year-old male bus driver suffered serious head injuries in the crash and was transported by ambulance to Singleton Base Hospital.

The children involved in the crash, including the Dunn brothers, were students at St Catherine’s Catholic College.

Principal Brian Lacey, has assured the public six psychologists have been at the school since 8am this morning, working with both students and staff.

“We want the children to be very open and to know that they’re able to grieve and that we will be here to support them through that process.”

He says they are very fortunate to have the support of a counseling team on hand.

Investigations are underway to determine the cause of the collision.
