BD, Agree whole heartedly, most FNs seem to be aware of the 'residency' issues and even those pre-approved seem to get looked over, too hard basket.
I believe the 'original RAAF' conversion course (where it wasn't via a full short term course or full conversion course such as joining a FIS to ATC course) was actually labelled the "ICAO Conversion course" and had a couple of FNs on it?
Now it's all too hard... But wait, breaking news, Civil ATC in OZ is 200 over staffed, big "official" announcement due soon, funny I had 12 calls to come to work on my last 2 days off... Sure, we're flush with staff, NOT!
Why are we over, you guessed it we staff for peak traffic (ie 5 or 6 ATC for 5 consoles open etc.), which only lasts for 5 hours a day, 3 in the morning on most positions and 2 hours in the arvo; so minimum staffing will actually be 2 or 3 people (average consoles open + 1) in most groups not the current 5 or 6; bingo 200 saved... Oh yeah plus a few part timers for the peaks; every day for 5 days of the week and a morning and arvo on the weekend...
