You are all arguing over semantics, the whole point is that AUSTRALIANS must come first. They are not, and have not been for a long time.
Can anyone name any other country in which a foreigner, non-citizen is kept over a national......? In a lot of countries foreigners have less rights than nationals. We are already doing them a service by A, giving them a job and B, giving them the same protection as Australian citizens.
An Australian should not lose their job and a foreigner keep theirs where it can be reasonably retrained. END OF STORY!
