A New South Wales Rural Fire Service water-bombing helicopter has crashed, reportedly killing its pilot.
Ambulance paramedics responded to reports of the crash at Woodstock in the Shoalhaven Area, after a call at 2.15pm.
According to The Daily Telegraph, emergency services have confirmed the pilot, the only person on board, died in the crash after the helicopter hit a tree.
The helicopter, a 1994 Kawasaki BK117, had been contracted by the Rural Fire Service to fight fires and was working on the Kingiman fire when it crashed.
The helicopter has been registered to Sydney Helicopters since May 2015.
"The NSW Rural Fire Service can confirm a serious incident involving one of its contracted waterbombing helicopters working on a bush fire in the Shoalhaven area," a RFS statement said.
"The incident occurred a short time ago on the Kingiman fire, burning west of Ulladulla."
A spokesman for the company told AAP they were still working to gather information and could not confirm details of the crash.
"Significant resources" from emergency services including a rescue helicopter have been dispatched to the area, a NSW Police spokesman said.
It's understood nearby naval base HMAS Albatross is also providing assistance.
The Daily Telegraph reported that residents in Hobbs Lane and nearby Evans Lane had been evacuated in recent days by fire crews working to control a 1600 hectare fire at Kingiman.
On Wednesday, those living west of Burrill Lake and along Woodstock Road were urged to have their bush fire survival plan ready as firefighters continued to battle the Kingiman fire.
Woodstock residents were told to seek shelter in solid structures as it was too late for them to safely evacuate.
