Why do Melbourne and Sydney have seperate frequencies to call when departing to a COBT controlled port yet other airports don't? Is this due to a higher rate of traffic movements that would impede the function of the SMC?
Many of colleagues think that ATC should have nothing to do with COBT and that the airlines should manage it themselves. But we have what we have.
At Sydney there are discussions that ALL domestic aircraft should call Coordinator 24/7 (not just those with a COBT).
