The ADAS Occupational SCUBA to 30m qualification (Part 1) is the first level of certification as a commercial diver. This course is a prerequisite for ADAS Part 2 (Occupational SSBA to 30m) and the theory component of this course explains to the student the role of a commercial diver allowing them to better understand the anatomy, physiology, physics and diving maladies related to occupational diving.

This qualification is most suited to divers conducting occupational dives for scientific, photography, media and inspection services.

The course competencies include:

  1. ADAHYP401A Work safely in hyperbaric operations
  2. ADAHYP402A Maintain effective working relationships within dive or hyperbaric operations team
  3. FSKNUM14 Calculate with whole numbers and familiar fractions, decimals and percentages for work
  4. BSBWHS201 Contribute to health and safety of self and others
