  1. Must hold a CDAA Cave certification or equivalent approved by the National Committee.
  2. Have logged a minimum of 25 unsupervised cave dives totalling a minimum of 25 hours in-water time using twin cylinders with a broad range of experience. No more than 3 dives to be logged per day.
  3. Have experience in at least 4 different dive sites preferably in two different areas eg Nullarbor, NSW, Mt Gambier, overseas.


Must hold a Rebreather certification for the unit intended to be used in the training. Must have logged a minimum of 50 post course dives, with a minimum of 25 dives (totalling at least 25 hours) on a rebreather in an overhead cave environment.
