I got a full set of fuel cards from these guys
Home - Skyfuel in around 10 working days.
The only carnet I don't have is the Shell card. But at all the Shell bowsers that I've used over the last few years, you have the option of flashing the credit card. Pretty much covers me for anywhere we go.
Too bad if you dropped in after hours or when the refueller knocks off early
....or turn up at the BP bowser at Newman to find that BHP had decided to shut off the power to the airport side of town. The half hour fuel stop turned into a 5 hour layover!
