Forgive my history knowledge as this may sound stupid but I honestly don't know the answer.
You New Zealanders came from Australia didn't you?
Is it possible for a New Zealander to just turn up on the door of Australia and start working for a living there and buy a house as he/she would in New Zealand?
Or would you need to apply for a Green Card INSERT INTO post VALUES (work permit) and have a suitable job title etc etc before being allowed in to stay?
Here in the UK, since we are part of Europe we can work in Germany and Spain etc without too.. much difficulty.
Just wondering what the situation is for you guys and Australia.
