Hi'ya Salma,
I'm in the same boat as you - sorry cannot offer any advice at the moment, but if I find out any more information I'll post a new thread.
OH is a Graphic Designer, I must admit reading the majority of job related and migrating threads most folks going to Oz seem to be tradesmen so we're a little apprehensive about finding work particularly as we'll probably be going on a skilled regional sponsored visa to South Australia
Good luck
