(TTH will put me right if that's not correct).
Almost exactly correct
mon brave.
The Chinooks (CH 47-Cs) were then still part of the RAAF rather than t'Army, Chas was on exchange with No 12 Sqn RAAF, then based at RAAF Amberley in Queensland.
Chas hit wires at the Perseverance Dam, near Toowoomba QLD, on 4th February 1985. His life-support machine was unplugged a couple of days later.
Following the wishes of his family, a number of his organs were used for transplants, so just maybe the Chubb kidneys are still processing the amber nectar somewhere dunnunda!
Don't know if it still bears the name, but the Amberley OM patio bar was renamed "The Chas Chubb Memorial Bar"
The wires and pylons had apparently been painted green - to pacify the tree-huggers........
