It is true that pilots are not on the Migration Occupations in demand List these days. Go
here for the curent list.
However, pilots are still on the Skilled Occupation List which can be found
here
In a nutshell this means an overseas pilot with the relevant skills and able to meet the points test will be able to apply for skilled migration (unsponsored) into Australia.
Whether they will get a flying job when they get here is another matter.
