As for Challenger TAFE, you will be firstly vetted by the college so that your technical and professional background meets the IMCA guidelines to cross-train as an ROV Pilot Tech.
Secondly, all those that meet those requirements are then ranked by an industry panel, with the top 8 selected. There are only a few ‘induction’ courses a year, unlike IDESS.
Do you meet the IMCA guidelines as descibed on the website below, if so, it doesn’t hurt to send an enquiry yourself does it?
