As your from QLD I will let you in on the situation in JT WA.
We have the RFDS and St Johns Ambulance based at the AD.
Also the new rescue helicopter service is based here as well.
The only missing service is the Fire Service (except Police who are useless anyway).
I agree about the fuel reserve issue, but I repeat that if the delay was considerable I for one would have diverted to Perth where emergency services are in attendance.
I think you would agree that a GA pilot/pax life is worth just as much as an airline Pilot/Pax if YOU were the one concerned.
