You'll find the full story of Commonwealth Marine planning right around Australia on the Department of the Environment, Water, Heritage and the Arts website http://www.environment.gov.au/coasts/mbp/index.html
In particular not ALL of those areas shown on that map of South and Western Australia will become Commonwealth Marine Parks. Those are just the areas which have been identified for further assessment. See the details in http://www.environment.gov.au/coasts...assessment.pdf
Lots and lots of details.
