Its kinda relevant...........
One option Albanese has, is to allow Sydney to dictate the size of aircraft it will accept. If they say that from July 1 2014 they will only accept 50 seat aircraft, those ports that have positioned themselves as hubs, with security and aprons and such, will win out. Rex and Brindapelican will have an economic decision to make.... service the hubs or go to 50 seaters. The government and SACL can say that the rural and regional slots are still available......to complying aircraft from a screened port.
Sydney won't care if some rural people can't fly direct, thats just a 19 seater they can replace with an A380 when the slot expires.
Nasty but possible.
