Have to agree with Walter. I went over there in 88 and saw the same two waves of Antipodeans. A lot of the '89ers ended up banging around on turboprops as the downturn started shortly thereafter.
I was involved in check and training, and the hardest job was normally training (or should I say de-training) mouthy Aussies and Kiwis, who had 3000+ hours GA time and thought they knew everything. Suffice it to say that they all got somewhat of a wakeup call when the first Euro winter hit...
By contrast the 300 hour approved course folk "got it" straight away and were generally a pleasure to fly with. Our company used to take on several of these folk every year, straight into the right seat of the 146, and we never had a problem with any of them.
It seems that many Antipodeans just can't help themselves when it comes to being aggressive and arrogant. Not all of them were like that, but the ones that were, were really bad news.
