Checkboard,
The Netjets model here in the US was built on a 50% utilization factor - ie 50/50 revenue/ferry, so a revenue out and ferry back might be feasible.
As far as the guarantee response is concerned in the US its 4 hours, but Netjets owners also understand that if we can't get a QS tail to them in that time we can send them a vendor aircraft. So a fractional operation has the option of using the existing charter fleet as necessary.
I think the big issue is demand.The Australian population last time I looked is 15 million plus. The population of California alone is over 36 million. Here in the US Netjets flys 70+ Citation X's (the plane I fly) while in Australia I believe there is 1 (VH-TEN).
Netjets was talking about starting an Asian devision (before the current economic woes) but my guess is that it will be centered around China. If they ever do start an operation in Australia I'll be the first to sign up
