The only people who may be interested in this in WA are CHC and Bristow.
98% of the flights out of places like KTA are done in clear blue sky so spending dough on more IFR type flight planning software etc won't be on the radar at all.
Also all the graphs and charts that people ever need are already in existance anyway.
Still you could always give the Chief Pilot a ring at CHC Australia 'cos it's his guys who are going to the Goodwin and the Rankin these days. I'm sure he'll be interested?
Good luck.
