DH originally got a job with Westrac and they advertised in our local newspaper. We are in the Riverina, and the mine is at Lake Cowal. A few years ago he switched from Westrac to Barrick (the company that owns the mine) as Westrac were only contractors and he would have a more stable job wtih Barrick. I think truck driving jobs start at $50k a year, but that is working a 4 on 4 off roster (so you technically only work 6 months of the year) plus you get fully paid premium level PHI as a fringe benefit of the job. You can also get rental properties as well. But the pay does increase with experience. In the maintenance dept where DH is, the pay range for a serviceman and TA is anything between $60 and $85k again depending on experience. Lucky for us DH is at the top end of that bracket It isn't hard work by any means, but the hours can be long. Apparently the mine where DH works is one of the lower paying mines as well. If you went to a coal or an underground mine the pay is often a lot higher.

ETA - Joeve, it would be the right site, but it just depends on what jobs there are available at the time I suppose. Another way would be contact the mining companies directly or even a recruitment agency as a lot of the jobs are done via labour hire companies as well.
