....we have one of the most unhelpful poorly workable ATC systems world wide!
Having been an ATC here in Aus. for many years before taking up a long career flying internationally, I can vouch for that.
Not the fault of individuals, but the system is incapable of dealing with large numbers of aircraft particularly in terms of runway departure and landing spacing.
This anecdote has been around for years:
Pilot to Australian ATC: You have the second best ATC system in the world.
ATC to Pilot: Who has the best?
Pilot to ATC: The rest of the world
