My comments are based on actual events and stories from colleagues. There’s a reason you need cash or CC, or PPR to use your carnet in Halls Creek, it will be due to unpaid fuel bills. Ask ex PELAIR pilots who worked there pre Norfolk ditching,when they were told where they could and couldn’t refuel in the Pacific due to unpaid fuel bills. Ask ex Broome based pilots about being sent out VFR in the midst of a cyclone , doing 16 hour days in a 210, landing after last light in a single with pax on board because the operator told them to come home -even with TEMPO conditions at Broome - because they didn’t want to pay overnight costs. Stingy operators not wanting to pay for expensive fuel do exist in Australia , it’s a fact.
