Why is it these days we can on most occasions get in and out of SYD (as big as it is) without feeder fix or holding carry on but MEL is every single arrival. Flying all over the country it stands out to me that MEL has something different. Even when there's hardly anyone flying you get a fix time which is then changed to cancel speed etc.
SYD and BNE copped it for years and the act got cleaned up well and truly.
