Oi oi,
Im a British Graphic designer with 7 years experience looking to move to Perth in the next couple of months, im currently working and living in New Zealand (Tauranga).
If anyone has any advice for me i'd be very happy to hear from you.
I work in design and we're heading for WA but as I'm still in the UK there's not much I could tell you.
Although there is a site you're probably aware of Australianinfront where you might be able to get some better information.
