I am in roughly the same boat although I will be moving over in Feb 15 & am more Renewables / Mechanical based.
I worked in 2008 as part of a WHV and found you could take CVs (resumes!) to companies but I didnt get anywhere through that route. Registered with a couple of agencies (Hays etc) and eventually found a job after a few months that way.
Can you send me a copy of the list too LouiseEP? Every little helps!
