notthesame , while your argument might hold some water were it not for the absolute shortage of crew in the market. From what I can tell aussies are making little to no difference in the current environment. I'm seeing people with the bare minimum 1500 hours in class, sometimes only single engine turbo prop time getting onto the widebody fleets, including people with no jet time making it onto the 74.
Also, Australia is not a cheap country to live, so the Aussies are not akin to cheap labour group happy with sub par wages and conditions because whatever they earn here is a kings ransom in their home country.
Time will tell what happens with other operators and the E-3, or any other visa for that matter because if things keep on going as they are the conversation will be very different further down the track. That is of course of there isn't a complete swing in the market again!
What I will be interested in seeing is when some pilots cotton on to the fact that if their spouse was on an E-3 instead of them, there would be absolutely nothing stopping them from applying to any of the majors as the E-3S (or is it E-3D?) visa isn't tied to an employer and provides full working rights
