Doubt that they are in the final stages of hiring OS controllers, a couple of the blokes here in the sandpit have been told that they must obtain their own permanent residency visa approval before submitting applications.
As an Aussie expat controller in the sandpit I am talking to more controllers from Oz about coming to the ME than foreign controllers going the other way. Heck half the guys I trained with on Tops are either here or in Germany.
Even the Yarps aren't overly keen on going to AsA as they were 4 years ago. Anecdotally feedback from the South Africans is more positive from those that joined the RAAF as controllers than those who went to Airservices.
So boys and girls about to embark on your career with AsA, do your 5 years get your Radar Area/Approach rating go OS do some really challenging ATC (without the AsA bull!!!!) and earn pretty good T&C's.
