The new airport being built in Rossmore will become Sydney's primary airport for major flight paths. It's inevitable that as such a huge amount of traffic starts passing through there, especially rich people coming and going from flights, that businesses will start opening up nearby. Hotels, rent-a-cars, public transport line etc.
Stands to reason that eventually all the major corporations will open offices nearby too, unless they want their executives and prestigious business partners to have to travel 50km to their current head office in the CBD when coming and going from major flights. Add that up over the next 30-40 years and it's looking very likely that we'll have two major CBD's in Sydney. Not sure what effect, if any, that would have on house prices and the job market.
Thoughts?
Without a harbour view, probably not.
