It will be more of an inconvenience to the majority of travellers, who I think would prefer to travel from Tullamarine. Obviously travellers in Geelong will be pleased.
If the 3rd airport in Melbourne’s south east ever goes ahead one day, that will only cause further confusion and inconvenience to many (as I believe the proposed site is out near Koo Wee Rup).
They really need to get the rail link to Tullamarine established. I think that would be the Number 1 air travel related concern of Melbournians (even though I don’t live there ).
