Part 66 was designed by the bean counters to eliminate man power costs. I full B1 guy can effectively operate on their own. How many Line maintenance task require specialised test equipment? Bye bye Avionic guy. They have been doing it in Europe for years. I know personally, B2 guys who now have a full B1 and don't know jack about mech stuff, same the other way. Fact is that now there is a shortage of licensed guys in Europe, and soon it will be in Aus. Until then we will be screwed over.
As for foreigners coming to Aus, whilst I totally disagree with the 457 Visa for aviation, a lot of Singapore LAE's paid out of their own pocket, took leave etc. Far more did it them selves than people I know from QF who were expecting the company to do it. Go do it yourselves if you are worried about your job, its happened, its crap and no amount of whinging will change it.
So when I come up to a job against you with my full CASA and EASA B1/B2 licenses you can only blame yourself.
