I contacted Challenger TAFE a couple of months ago to see if they still run their ROV course and got the following reply:
"Thank you for your enquiry. We haven’t run an ROV course since June 2009 due to the low demand for trainees at the moment. We schedule our courses to meet industry demand to ensure our trainees have the maximum chance of gaining employment in the industry. At the moment, it is not a good time to be entering the industry, in Australia at least. There is a glut of experienced personnel, partly due to the global financial crisis, and partly due to recent tax law changes encouraging operators working overseas to return to Australia for the higher rates, now that they have to pay more tax."
One of my friends was on that last course, a Navy Electronics Technician, and he was unable to secure a job on completion of the course.
It would be worthwhile contacting the TAFE again though as things may have changed.
Cheers.
