Tin Man
Write to all the companies and employment agencies - they are desperate for workers over here.
I came over 3 weeks ago to work in the Queensland coal mines for a company called Macmahon - check out
Macmahon Holdings Ltd for available jobs or just to contact the HR dept. We have mines throughout Queensland and WA so something may be suitable.
If this fails I think your best bet is an employment agency - Barclay Recruitment in Brisbane helped me get my job.
Good luck
