Aus, over the last 20 odd years since I did my licence I have seen about 4 or 5 boom and bust times for recruitment in to the various airlines. On another thread a while ago I was howled down by " experienced" fellows from Bankstown who didn't believe there would ever be a shortage again.I would only say to you to go for it because as sure as the old sun rises in the east ( I think ) there WILL be a shortage and an over supply and another shortage all probably before you get the minimum hours up!!
Good Luck to you
