AsA tend to actively recruit ATCOs from the RAAF every few years and a number have moved across into civilian ATC. If you serve overseas whilst in the RAAF (on deployment) you should be issued an ICAO license. A number of controllers from the RAAF have kept their ear to the ground whilst in the military, made contacts (the way of the world) and are now working civilian ATC in NZ and Canada. However in nearly all cases (even AsA) the controllers still had to sit exams for the agency they applied for. The RAAF is always looking for controllers and its a pretty good way of life with good pay and the opportunity for deployment in the current world political situation. As with most ATC agencies management is often griped about - but I'm sure plenty would agree with me that the "grass is not always greener on the other side", there's good and bad to every job!!! Good luck
