you can't be VH registered and be administered by CAAS. CAAS only regulate 9V aircraft. The Jetstar A330s in Sing are still administered by CASA.
Exactly! Anyone who actually works for Jetstar would remember the debacle, one reason big bad Bruce is now selling face cream door to door in Asia, where he tried to put the 330's on the Singapore register. One of the first things they wanted was a proper crew rest so they all stayed on the VH register. I think Bruce thought it was going to be as simple as changing the rego of a car.
