Keg you're probably right. I do go over the top sometimes....I apologize.
However a couple of points are valid whether I make them or not. Over the decades, and not just since '89, Australian pilots have been heading OS for jobs. I did it, for years, you probably know pilots who've done it. Many young Australian pilots now start their jet careers OS. I just feel uncomfortable knowing that and then seeing the "Australian jobs for Australian pilots" stuff.
I don't think that there's going to be a flood of 457 DECs. There may be some but unless JQ are very foolish, there wouldn't be one qualified F/O missing out on a command because it was taken by a 457 driver. That way would lie instant lawsuits and ministerial ntervention for sure.
