the rim - I think you have mis-read the situation here. There are plenty of very capable LAME's overseas no doubt, but they should not be used as a substitute for training in this country, especially when we are to be confronted with a large number to be unemployed shortly. Believe me, Singapore, for example have no qualms in giving expats the bullet when times are tough.
Unfortunately, the 457 Visa system has been abused by a few shonky companies as a means to drive down wages, training and employ "compliant" staff.
