SS, if you knew anything you would see that VS's loads are low on the HKG-SYD-HKG, and they are pushing for VA to do the run with the link up in HKG, there is also a push for PVG.
As you said the other obvious one is to SIN but it won't be through CNS, seriously? JB is pushing for business orientated routes, like PER-SIN to link up with ETD And SIA. IMO the first stage of any expansion will be out if SYD.
