In recent years, to meet the requirements of the Australian Skills Quality Authority (ASQA), ADAS has modified how it delivers the Diploma of Hyperbaric Operations (Diving supervision) to onshore supervisor applicants.  The new program allows for more time to learn the broader skills related to effective supervision within the workplace and covers assessment of skills best demonstrated and consolidated with on-the-job experience as well as reinforcing existing knowledge and introducing some new concepts.

Candidates who have completed the face-to-face Part 1 (SCUBA to 30m) or Part 2 (SSBA to 30m) supervisor course since the changes were implemented in 2016 have received the ADAS supervisor card to allow them to undertake work as a supervisor.  In addition, they have received certification to show partial completion of a Diploma of Hyperbaric Operations (Diving supervision).

NOTE: People who completed the ADAS Part 3 (SSBA to 50m) onshore supervisor course since June 2022 will have already received a the full Diploma of Hyperbaric Operations (Diving supervision) 11038NAT.

ADAS has developed a process which allows ADAS onshore supervisors who hold a partial Diploma of Hyperbaric Operations (Diving supervision) to gain a full Diploma by completing a structured learning program combined with logged work experience.  Applicants will be required to obtain workplace experience as a dive supervisor, complete a workbook and an online learning program, maintain a dive supervisor’s logbook and undertake a final theory assessment which is arranged directly with ADAS.


The process to gain on-the-job experience and eventually apply for a Diploma of Hyperbaric Operations (Diving supervision) involves a number of steps to be completed by onshore supervisors who have completed the ADAS onshore dive supervisor course with an ADAS Accredited Training Establishment (ATE) and have gained employment as an onshore supervisor.

The process includes:

  1. Submit an enrolment application form directly to ADAS
  2. Gain access to the ‘Onshore Supervisor Pathway’ short course on the ADAS online learning site
  3. Be employed as an onshore diving supervisor for at least three (3) months
  4. Build up at least 80 logged hours in a supervisory role
  5. Complete the course workbook, assignments and quizzes
  6. Submit an application to ADAS requesting final assessment (which will include logged evidence of supervisory experience; a review of your workbook, assignments and quizzes; a final examination; and interview with an ADAS assessor)

Once an enrolment application is submitted to ADAS it will be processed and access to the online training materials and assessment will be provided.

After the online course is completed and the assessment application is submitted to ADAS, candidates will be contacted to arrange the exam and interview which will be conducted by ADAS via internet and phone.
