Forever in too hard basket ?
This debate continues ad nauseum.
Firstly, from my reading, Sydney is not at full capacity yet even with the curfew.
It is a great asset so close to the city centre.
I agree with Blackbird 71 and DirtyPierre, Richmond RAAF Base has much of the infrastructure, is not surrounded by suburbia and is within reasonable distance of city area.
Why not make it a joint civil military facility, there are heaps of them in America working together OK.
And surely more of the GA traffic could use BK.
Suggesting places like Goulburn and outer Woop Woop is just nonsense.
Same old situation though, everyone wants easy access to a good airport, they just don't want it in their backyard.
