A Channel Ten cameraman has described being flung from the cabin of a helicopter as it crashed at Baskerville, in Perth's Swan Valley.
The helicopter was filming a truck rollover on Weir Road on Saturday when the accident happened.
The chopper came to a rest on its side, having lost its tail rotor in the accident.
Radio communication from the Department of Fire and Emergency Services reveals the pilot acted quickly to prevent a fire.
"The helicopter pilot has asked us to put foam on the aircraft ... while turbines are still running. Helicopter on its side - we are taking shelter behind the embankment."
Cameraman Adam Delmage was taken to Royal Perth Hospital with back pain but escaped serious injury.
The pilot did not require hospital treatment.
Mr Delmage says he only knew to brace for the impact because he had recently completed a helicopter safety course.
"If I didn't do my HUET course and it wasn't so fresh in my memory I wouldn't have thought to do that," he said.
"But I knew I had to brace myself and prepare myself for the worst.
"The way the chopper hit, then it rolled, I kind of got flung out of the cabin and was hanging over the door.
If it had of rolled one more time I wouldn't be here."
The company that owns the helicopter, Heliwest, has issued a statement praising the pilot for making an emergency landing in difficult terrain.
The Australian Transport Safety Bureau will investigate the cause of the crash.
