About CDA

 CDA is proud to offer the widest range of qualifications of any ADAS & certified school; from beginner divers (Part 1) through to saturation divers (Part 4).

World Class Systems

The Commercial Dive Academy – CDA – facility was initially set up by the Commonwealth Government in 1993 to meet the increasing demand for offshore Oil, Gas and Marine Divers. It was set up at the highest (world class) level as only Governments can afford to do.

In 2019, CDA has just completed a full upgrade and refurbishment of our Saturation barge which entailed installing a hyberbaric rescue chamber, TUP Piece and Clamping.

100 Percent Employment

Not only does CDA offer  the widest range of qualifications and train the largest amount of divers in Australasia, but we proudly boast a 100 percent Employment rate for graduates of all levels of training in 2018 and 2019.

As far as we are aware, we are the only Commercial Diving school in the world with these results.

The majority of our graduates will enter into civil and construction work with the rest dispersed across industries such as aquaculture, science, and media

Industry endorsement

In 2019, over 100 students attending our courses were sponsed by companies.

This a testament to our world class systems and being the world leaders in diving training.

We believe that we are the only dive school in the world recieving this level of industry endorsement and support.

We have had sponsored students on all levels of training, including scientific training for Australian Universities to construction training for companies in Oil and Gas, Salvage, Aquaculture and onshore construction.
