Interesting. I am an american living in Mindanao, in the southern philippines, about an hour south of davao city. I'm a relatively new diver, with about 80 dives since last spring under my belt. 95% of the dives in the Gulf of Davao and a couple in Sarangani Bay, in the southern part of Mindanao. I learned do dive here last spring and all of my diving has been here in the philippines.
As I read the story, it seemed that the dive operations there are like those here: definitely adecquate on safety, but having been born and raised (and worked for 30 years) in the USA, I'd say that US safety standards are probably a tad on the "anal" side.
As the story is relayed, the divers were in a situation that required some experience and it also seems that the dive OP wasn't babysitting them either, having just razor thin DM coverage and, it appears, the DM's probably were a tad on the loose side...in terms of keeping people appropriately corralled....a necessity if you only have a couple of DM's on a dive with a strong current.
I think was actually made the difference between life and death for the diver...and led to a tragic outcome....is that (somewhat like in the philippines) if you have a "situation", you cannot assume that when you get the victim back on land that life support and medical care will go from "advanced first aide" to first class, state of the art life support medical care. In fact, if i read the story correctly, the victim was probably quite saveable...until she was taken off the boat and put in the hands of local medical care. Things should ramp upward at that point; it seemed that the word "incompetent" would be a wild understatement for how bad the victim's care was once she was taken off the dive boat.
In closing, I understand how, from an american or austrailian perspective, you would expect the dive op to cease operations, at least temporarily, when a fatality occurred. And, the dive op did have razor thin resources to medically assist a diver and they definitely should have taken the accident as a red flag to up the ante on DM supervision and medical support of divers but..it's Fiji...not Austrailia or the US. Adecquate or meeting requirements may be how a US or Austrailian dive op conducts business. Here in the Philippines or in Fiji the standard is closer to "good 'nuff" and it actually may not be "good 'nuff" it the situation is severe. And assuming that 'if we just make it to shore things will improve...' might be a fatal error.
