Exactly. I remember once chopping a branch off a tree in the water. I felt like I was ringing the dinner gong. A fishing lure was caught in the branch out about ten feet out and seven feet high, in a branch which first went down, dipped in the water, and then rose up. The lure I have had since 1983 and when it got stuck, I walked back to camp, later that evening walked back with a axe to cut the branch off. Took about 50 cuts. The dinner gong was really sounded! Lucky we were probably too far up river for salties.

PHs and other staff do stuff around and in the water all the time. Some clients are so scared of it they won't go 50 metres near it ... at least in my experience with one scared turkey.

One thing people do a lot is get water for drinking, cooking or washing. Crocs have been known to lurk at such spots. And I know from personal experience, you think you OK, I can see the crocs, I am wary, then you see a croc very very close, previously not seen.

No idea what was the cause, foul play or a croc. Either is possible. Not enough facts to determine either. But the poor guy did end up in a crocs belly.
