Well, I can tell you the culture is very very different overseas compared to Oz. The regulation in Oz makes it hard for the controller to act efficiently. You are not even allowed to direct track an aircraft. Yes, that's right.
not allowed.
I don't think you are going to have a problem with old controllers any more anyway. I believe the Germans are about to increase their number of trainees significantly. And I also believe the Aussies in the college are doing a sterling job, and therefore job opportunities will be available for those who are blocking your desired and necessary progress to move overseas. The rest will retire.
Also Dick you may find that the 'new young controllers' are waiting for their 5 year $70k training bond with ASA is up so they can head off O/S to pick up the big money.
They are not even waiting for the 5 years. My information is that the Germans will take anyone who is qualified and licensed. This is for the guys under 40.
