Hi Jo,
I have just responded to the survey. I kind of got the impression that wrecks should be protected, and wrecks can be dived, were assume to be mutually exclusive. I strongly believe wrecks can still be protected and be dived, so long as appropriate care is taken when diving (is there any point protecting something that noone will every see?) But i'm not sure my belief would be concluded from the questions asked. As an example, the Yongala is prob one of the best wreck sites in the world, it was not deliberately sunk, but it is illegal to penetrate it.
Also when responding to questions about qualifications you really need to consider diving a wreck vs penetrating a wreck - i.e. should additional qualifications be required (which there are for penetration). So i found these difficult to answer it depends on how you dive them as to whether quals should be required. Protection aside, its very dangerous to penetrate a wreck without appropriate training, therefore i had this in mind when responding to the questions, more so than protection of wrecks (which training is also very important for!!) . But i have a feeling its maybe not what you expecting the consideration to be?
There also laws in place in many areas about what can be removed or moved around a wreck with penalties etc. But i'm sure you know this!!
Great to see some surveys on it! But comments sections may help as i feel that too many assumptions could be made based on the answers, which aren't actually right. i.e. some of the questions were a bit leading.
But good luck - I wish you well!! Wreck diving is huge down in Melbourne. Maybe try get your survey out to some of the dive clubs down here.
