Agreed
As an Int'l widebody Capt with a fair amount of experience SYD is down at the bottom with PER, & Calcutta!(these 2 ATC in particular) Seriously. SYD though vies for bottom place due the 6am chaos from Holding-ILS-Immigration-quarantine. Appaling. Methinks all the management staffs there should be givena a freebie to a modern efficient airport (eg FRA / LHR) to see just how ATC / genuine large no of I/B pax should work.
But unlikely as undoubtably 'they know best'
