After flying home from Narita last night. Getting from tokyo to narita airport was absolutely stuffed. After a 1 hour train ride, swapping trains 3 times and $40 out of pocket i got to Narita airport and supposedly Japan's public transport system is meant to be good.
I can only imagine how long it will take for someone like myself who lives on the east coast of Sydney (Sutherland Shire) to get to an airport somewhere in western Sydney by public transport. And also how expensive the taxi fare will be (to get to Sydney airport from my house the cab fare was $80.
My suggestion would be to just to expand the airport we already have by somehow extending the 16L/34R runway so that A330's, 767's and 787's can take off and land and building a runway parallel to the 07/25 runway.
