hiya, dont know if you are still looing for any advice, but me and OH are in the same position and i called Go Matilda, they have links on here,they were really helpfull and we came up with the best option which would be sponsorship from a company who are prepared to offer him a job.
You could try the Oz recruitment agencies, links on different threads on here or what I am considering doing which is setting up a week visit for hubby to go to Perth where we want to move to and he can look for a job and suss out the likelhood of a sponsorship, apparently there is a better chance of this if you go out there, it shows you are keen.......
What ever you decide to do, good lck with it
