Agreed, although I don't think 'want to be divers' would have access to the wrecks. In my experience you need a good skipper, and lots of kit, and most importantly hot dogs.
Also agreed, I have not dived those wrecks for a long time, but there was a skipper [I will call him a skipper only because he owned the boat, no names as he is still alive, how I don't know ], who took divers to the Anne Miller who should have NOT dived this wreck, no training for this depth, and gear required for this dive. Single cylinders, no backup gas or deco gas, just a few things missing FFS.
I have saved 4 divers from this wreck, two out of gas on the wreck, one out of gas on the way up to the deco [a civilian OW Instructor], and one narced out of his head lost going the wrong way [pro underwater cameraman filming the wreck], I dragged him to the ascent line and up until he 'snapped out of it', the only one to say 'thank you'.
I was diving this wreck with pro divers only the 3 dives this happened [Navy and 2 civilian commercial divers twice, and Navy divers the last time] we had ALL the required gear and backup [and a chamber on our boat the last time], their boat would be lucky to have O2 and a first aid kit.
This was a long time ago, and WHS have come down on the 'cowboys' since.
Oh, and I remember sitting in the Navy chamber at HMAS Penguin for 4hs 45min with a civilian bent on this wreck, the doctor of underwater medician 'volunteered' me to watch him.
Such fun, and forget the hot dogs, rubbish.
Please take care.
