We are in the process of getting our skills assesed so your probably ahead of us at the moment, however just to put your mind at rest we had a conversation with a friend of ours today on skype who's allready in preth and he's mentioned that there are loads of jobs for Engineers out there (He moved out 3 years ago and had 5 interviews and 5 job offers within a week of arriving) He applied as a fitter but is now an engineering manager for a company that makes composite materials for offshore use. Like yourself i've applied for a few jobs but have had no luck, but having spoke to my mate he says most companies need some assurance that you will actually be emigrating indefinetly before they will even consider you for a position. I have spent 15 years in the steel industry along with currently inspecting power stations, chemical plants and refinerys so i'll be looking for work along these lines. You may have to diversify into something else but with your background you should have no probs. Where are you looking to emigrate to.
