Those signs on the riverbank saying not to swim with the crocs......ignore them.

There are lots of places that are 'out of the way' and don't have such signs; I recall a young tourist (a woman from the US) having a swim in the top end of WA and being taken by a saltie. A colleague (Su Solomon) was, at that time, researching taphonomy and specialising on identifying predators by identifying and classifying tooth marks on bones; she was the one who identified the East Kenyan "first family" hominins as a collection of crocodile victims, by comparing them with recovered victims (in the morgue) from our Top End. Su had a cartoon on her door, depicting a pair of crocs post-prandially sunning themselves on a river bank and saying "That was lovely. All soft and pink, with no claws or horns."
