Current VB policy is to avoid where possible a diversion to a non-network port such as Kal or Geraldton, so where wx in Perth is forecast to be below approach minima, diversion back to Adelaide or Melbourne is required. Having a set of stairs and an arrangement with the Kal refueller would save them considerable fuel on Perth flights and greatly improve operational integrity across the Bight, enabling aircraft to linger longer at Per, with greater chance of getting pax where they want to go.

Towering Q I meant to mentioned Forest as an emergency diversion field (ie rather than land off airport somewhere) I think Ansett used to use it pre-ETOPS for east coast to Perth (i may be mistaken) and I was curious if this is still held by any operators.

With VB crews normally doing a sector (or two) before heading to PH, the problem would be having an aircraft on the ground in the middle of the night, at a port with no ground handling services, and an out of hours crew. That would be a big mess!

Hedge, our definition of "regional" airports differ greatly. With the exception of LEVX and LFQQ the other "regional Eurotrash airports" you listed are all (my Company) approved suitable international alternate airports.

In the Perth (YPPH) area the only suitable international alternate airport is Learmonth (YPLM). That airport has no ILS and is just under 1.5 hours flying time from Perth. Geraldton (YGEL) and Kalgoorlie (YPKG) are what I define as regional airports. :ok:
