My own experience, hubby was offered a job so we were lucky in that aspect, if we had come here without work, even with his experience it would have been difficult, especially as he is applying for other jobs whilst in a job and been promoted twice, but I have been looking since last December!, I have applied for well over 500 jobs, not even being choosy, I am HR qualified, have extensive PA/admin experience, still only had 1 job which lasted 2 months and they found me on LinkedIn!!!I have gone through every emotion from frustration, deflated, worthless etc......I am now looking at retraining and getting the all important 'Australian' qualifications, aswell as doing some voluntary work.
i think if we had come out here on our own steam, as originally planned, we would have headed back by now, so I would agree if at all possible secure a job before arriving, it is a great help.
