Willamtown already operates A320 & B737 domestic flights to service the 1.4 million people in the area, which is more then the south coast can get at Illawara (Wollongong).
Are we suggesting that a population base of 1.4 million people needs an International airport?
Fast Rail to Sydney. We are talking about NSW here aren't we? If they can't figure out how to build fast rail down to the Federal Capital, I doubt they would manage a fast rail network to service an international airport 2 hours north of, wait, another international airport.
And once again, where is the money coming from? There is NO MONEY now to maintain & operate the existing infrastructure.
All this talk of additional airports is just a smokescreen is distract us from the present contraction of the economy, by starting a conversation on the return of good old unending economic growth.
