negate the need for aircraft coming from the indian ocean and accoss the nullabor to tanker fuel due to legalities. That will save the airlines big money and make Perth more viable.
Perhaps the internationals, but interstate flights can use all the other ports: Gerro, Kal, Meeka, Learmonth. A330 could carry Auckland?
The question is, with Cat III shortly to be available at Perth, how many
actual diversions will occur, and will the tankering of an occasional extra 2 hours-odd of fuel for Learmonth/3 hours for ADL offset the huge cost of what would be effectively an international airport that will never be used?
