The ADAS & ADCI Part 3 course for air diving to 50 metres, is an internationally recognised qualification which is also recognised by the International Marine Contractor’s Association (IMCA). This course is for aspirational divers who do not want to spend their career onshore on fish farms or living contract to contract as an onshore civil diver.
The offshore diving course is for the diver looking to become an underwater welder, salvage diver or just someone who wants to have the option to make big dollars when the chance arises. The ticket will allow you to work in any country in the world and on any dive site if the depth is under 50 metres. Divers will also learn to be hyperbaric chamber operators during the course. Finally, the course is for those crazy enough to dare to become saturation divers as you must hold your ADAS Part 3 ticket for at least one year before enrolling on this course.
ADAS Part Two ticket
- To enrol in our ADAS Part 3 (Surface Supplied Air to 50m) course you must first have completed our ADAS Part 2 course. Your ADAS tickets need to also be current.
Current Commercial Dive Medical
- Before we can allow anyone to dive, they must hold an occupational dive medical compliant to the Australian Standard (AS) 2299.1.
- The doctor who assesses you for medical fitness is required to be trained in hyperbaric medicine and certified as an occupational diving doctor.
- You can find dive doctors using the SPUMS website: https://www.spums.org.au/
Current First Aid, CPR and Advanced Oxygen Resuscitation certificates
- To meet the AS/NZS 2299.1 and ADAS requirements anyone who joins a course at CDA, or any other ADAS school is required to have a current first aid, 02 provider and CPR certification.
- In general, if the card has First Aid on it, and the course was about a day long, it is likely this will be accepted. Though if you are not sure if your First Aid ticket is accepted, you can contact us any time to find out.
