I was reading thru the list of the proposed allowable things and note that if you want to photograph things you would need a permit.

Why?

That draft you are referring to is from 2005 and will not be the final result( it certainly needs editing and much clarification). In our national parks on land when a commercial film crew moves in they are required to seek permission (get a permit) and fix up any damage and they may also need a ranger or someone to help them out. The intent would be the same for a marine park. If a commercial film crew wanted to do a production they would have to seek permission, take advice on impacts and minimise disturbance etc while using a public resource for profit.

Ok that bit about "for profit" makes sense, thanks for the reply
