I'm glad you feel the Oz system is as you prefer it, for me getting thumped with a 10 minute delay 200nm from dest is nothing short of a scandal
And yet haughtney this is precisely what happens in Dubai and London! On occasion in Dubai the delay can be much more significant as well. It was also a regular thing into Singapore and Bangkok back in 2007. Sure they let you slow down, as will Ausse ATCO not that it does much good at 200 miles.
I'll admit that my international destination list is not extensive but four of my regular destinations are amongst the busiest in the world- and I operate into them at their busiest times of day. The Aussie system ain't perfect but it's no worse than anywhere else.
