Professional Divers' Association of Australia was an Australian trade union which existed between 1969 and 1991.
[1][2] The union had coverage of all workers employed underwater in Australia, principally as professional divers.
[1] The PDAA was established on 1 May 1969 at a meeting of several divers, dissatisfied over the lack of job security in the diving industry, Occupational Health and Safety issues, and the significantly lower wages received by Australian divers compared to their overseas counterparts.
[1] The PDAA was strongly active in maintaining and improving its members working conditions, and undertook several strikes during its history.
The MUA continues to provide representation for professional divers in Australia.
