Course Overview

The emphasis of the Restricted Occupational SCUBA to 30m course is to prepare recreationally trained divers to work safely and effectively as members of an integrated occupational dive team in reasonably controlled environments that involve negligible risk from environmental hazards, underwater entrapment or risk of unplanned decompression. Whilst the main emphasis of the course is to dive using half face masks and mouth held regulators, during training, students must use a variety of modern diving equipment including full face masks with effective communications. They must be assessed as competent to complete a variety of relevant light work, sampling and survey tasks.

Course Standards

The course meets the requirements of:

  • AS2815.6 – Restricted Occupational Scuba Diving.
  • Partial completion of Certificate IV in Hyperbaric Operations (Occupational SCUBA diving to 30m). National Qualifications Code: 11006NAT.

Note: If you study at an ADAS training establishment outside of Australia you may not be eligible for the Australian Qualifications Framework certificate. The ADAS licence, however, is issued at all ADAS training establishments.
