Found this exchange re Aussies at US regional, Piedmont. I wonder how many Aussies (E3s) came, made it to the line but have voluntarily left for one reason or another:
“Speaking of interviews, seems you guys are hunting for Australian new hires?
How many do you have?”
"Half Dozen, or a Dozen or so? Some Kiwis too."
“One of the first ones hired recently just returned though. He got tired of the terrible schedules that go along with the low pay.”
