Disco Stu: Sydney, the 1st airport to slide ingloriously back into the 3rd world.
Pretty sure there is not a single piece of airspace that AsA "adminsters" that has not been TIBA (= 3rd world situation) in the last 18 months.
Remember, our EBA only expired just over 1 month ago. The delays are due to staff shortages, as outlined by Max1 above.
