The Media at it's best (!).
Personally, I thought it was a load of toot, but what I will say is this - Corporate Australia has a bad habit of not recognising people's overseas experience and rewarding accordingly, from either migrants or Aussies. There are some Aussies who have been overseas (e.g. chefs), come back and the attitude has been "yes, that's really nice, but what exactly did you do when you were over there ?" because it's not "visible".
They said "I might as well have stayed at home, done the same work here and the same years, instead of trying to bust my gut to get ahead - because it counted for nothing, and if I had stayed here, I would have been promoted faster".
Got to agree, that was very much the attitude I got both times from UK and Aus when I was trying to get a job - when I came 1) back from continental Europe to UK and then 2) migrated to Australia from UK.
