Hi - Hope anyone can help. I am looking to work in Perth for a year starting in October 2013. I have booked my ticket. I am a NVQ level 3 carpenter. Can anyone tell me what I need, to start work, apart from the working visa which I have already got. I am reading about a blue / white card but have been told I do not need this in Perth. Is there any other paper work that is required to go on site? Also when looking to introduce myself will employers recognise the NVQ qualification or will I need to know the Aussie equivalent? Thanks for the interest
