I cannot see for the life of me why when the RAAF moves out of Richmond, the airlines can't move in. The basics are already there, there is already a rail service that goes straight thru to SYD, that can be diverted to Mascot, and a fast light rail system could be put in place. For all my years of spinning around the world, I have come to accept the travel between airports, which is pretty norm for the rest of the world, but the Australian public have been spoilt by airports close to Cities. The RAAF are heading north in the next few years so this surely has to be a consideration.
