Two buses in the long-term parking area of Sydney Airport have been destroyed by fire, which authorities believe was accidental.
On Sunday afternoon, the driver of one of the buses noticed his vehicle was having mechanical problems and left his bus parked off Ross Smith Avenue, Mascot, to get some help, NSW Fire and Rescue says.
While he was away, the vehicle was overheating and caught fire.
The fire spread to the bus next to it and then to a third one.
The airport fire service and NSW Fire and Rescue put out the flames but the two buses were "completely destroyed" and the third severely damaged.
