Well said IHD. Face it, the Sydney basin will only ever have one major airport. The horse has bolted. It doesn't have the infrastructure, space, and money for capital expenditure and never will now. The best thing to do for Sydney is move the international ops out of there and make it a purely domestic airport. Any satellite airport for Sydney; whether it be Newcastle, Orange, Bathurst, or wherever, may as well be out of state. It's all much the same for travel times in connecting flights. For example, Brisbane has a lot of room for expansion into Moreton Bay. If it wasn't for the fact that it's privately owned, it could serve Sydney as well as, if not better than any secondary Sydney airport. Same applies to Melbourne.
