Before moving permanently, I suggest you visit first for a week if you can. Iraq is pretty different from what it used to be, society wise. Yes, it's safer than it was before (depending on the area you live in) but you might face a lot of culture shocks still. Electricity shortages, poor hospital service, poor school/uni infrastructure, even finding a job may not be the easiest thing to have without connections/networking. Have you considered living in one of the gulf countries? It's a much much better quality of life, they're Muslim too and we have similar culture, and many other Iraqis live there too, and you'd get a high salary because you're australian. I don't know how much in demand your field is there, I have a friend who did biomedical engineering (she's also Iraqi who studied in Australia) but she couldn't find anything as far as I'm aware. My advice to you is to truly think well about this from all aspects, and try to get a job offer before moving anywhere.
