I still fail to see what that has to do with airmanship. IMO it is still a courtesy issue. I have never seen anyone push anothers aircraft out onto a taxiway, no matter how upset they may be. That's not in anyone's best interests. Are you sure he was a local??? Would be interested what time it was you got there... with QN being a daylight hours only airport, it's very very unusual for there to be no-one on the airfield at all at the time of your arrival.
No comment on the phone issue -I don't know the circumstances, his or yours. Seems from your post that he did track you down to tell you he had shifted your aircraft though... strange he wasn't about for you to ask earlier.
