Operator was Heli Charters - formerly Downunder Helicopters.
For those that know the crew there, the pilot was Steve P. Not the owner, Steve S.
I have no idea what went wrong but I suspect (pure guesswork) turbulence may have played a part as suggested by the pax. The crash site is at the foot of a small range of hills/mountains. Does any one know what the weather was like there today. Glad to hear there are no fatalities be it by good luck or good flying.
Hope you're up and about again soon Steve.
