Never heard of any O2 filling accidents in Oz. I'll ask
around though.

No. Jammer said, three times, that the nitrox-marked tanks
contained air. Not 21% mix. Here it is again:

          "The lodge's tanks were all clearly marked
          with nitrox stickers. They all contained
          air. The captain waved his hand at the rear
          of the boat and said "All my tanks have air
          in them." The diver went back to the back of
          the boat, looked around, saw 12 tanks with
          nitrox stickers, (all with air in them) and
          our four tanks with no stickers, filled with
          nitrox."

It's mis-use if the tanks are no longer nitrox-clean.

You're right. Shoot the boat captain. Seriously, it may have
helped if Jammer's tanks had nitrox stickers AND had the MOD
clearly marked. Then the victim may have gone for one of the
other tanks or queried the captain. At least then the
captain's stupidity wouldn't have compounded the stupidity of
leaving unmarked tanks with high ppO2 unattended on a dive
boat where untrained divers were changing tanks.
