One thing all prospective ASA employees need to look at really closely is the roster that guys in Australia work. The guys still working there can give you an up to date idea of what they work now, but from all reports it's still not great with lots of quick turnarounds (ie 10 or 11 hours between shifts). Never realised just how bad the E,A,M,N roster was for your health till I left and started working a 6 on, sleep, 3 off roster, where you have 2 mornings, followed by 2 afternoons, followed by 2 nights. You can actually have a life with your family during your work cycle. This is a very serious consideration to anyone looking to go to Oz.
Also posted on NZ ATC jobs thread was the comment that in Oz you can work 10 on, one off, 10 on etc. (not rostered that way but with O/T), whereas here in the Middle East, we are required to have a minimum of 2 60 hr (2 and 1/2 days) breaks every 30 day period, and any time we work 7 shifts in a row, we have to have a 60 hr break after it. Sometimes it means you have to go without the odd overtime shift in the name of fatigue management but in the long run it is a good thing. I think sometimes you need regulations to protect people from themselves, and being allowed to work 10 on, one off, 10 on, is not protecting people. Again another very important thing to consider.
