I just confirmed that he also hangs out next to the south most murloc huts along the Eastern beach just north of the Exodar.  The coords are 34,27.

I stake my rep on this site that this is accurate.  Please add this to your list.  I noticed on both wow head and here at thottbot that he seems to also spawn around that beach, so when I could find him no where else, I checked there and found him on the land side of the huts (not closer to the water), but still on the sand.  I hope that helps!
