The whole Oz ATC setup is decidedly third world masquerading as first world. In a country as vast as it is, with even vaster oceanic airspace....who in their infantile brain thought that trying to sequence traffic once it was within 35 min flying time of destination..was a sensible idea?
I know who....a person or organisation with no clue as to how aircraft are flown or operated...that’s who....or better yet an organisation or person who wants to reimagine aviation their way...
