This is because none of the hardrock underground mines in Australia (Gold, Copper, Nickel, Lead, Zinc, Silver and everything except coal) can use these formal qualifications. All the hardrock underground mines have to issue their own equipment tickets and procedures on site. These are non-transferable tickets. This means that the 3 day truck driving RII tickets are useless, for the hardrock underground production mining jobs. The last TAFE to run a course I know of, was in Bendigo Victoria, that stopped years ago. So why are there so many units but no courses?
