The Perfect Location

Located in the picturesque town of Beauty Point Tasmania. The Commercial Dive Academy has two main diving locations. Flinders wharf is where the shallow diving takes place. The deep water dives are operated from our lake Cethana site.

Lake Cethana is the only location in all of Australia that is authorised to train offshore surface supply divers and closed bell (saturation divers) best of all it is stunning!

Luke Moxham ADAS Part Three Surface Supply air diving course

“I have just recently finished my ADAS Part 3 at CDA, one of the biggest things I noticed was that students even from Part 1 and 2 were being trained exactly as we would if we were working on an offshore and onshore worksite. I think this is a huge help for anyone who would be starting new into the industry or continuing, something I feel I missed out from previous training elsewhere. On top of the high quality of training and experienced staff I appreciated the help I was given to find work afterwards.”
