Bob, we've had some ! Fishing the Top End in a tinny, we were free lining blueys into likely barra spots and slowly retrieviing them as we drifted uo a tidal creek. One spot seemed pretty good, several barras around the 10 lb mark. So we put the hook down. After a bit I got snagged - pulled for a break, and the "snag" went away across the bottom. then climbed up the creek bank and revealed itself as a 4 ft saltie. Then Norma hooked another "snag" - a 6-footer this time . We had a few more. "Al" I said to the guide, "is it my imagination, or is each croc we see bigger than the one before ?"
"Too right" said Al " and as the last one was 10 ft the next might be trouble" He drew my attention to the gashes on the side of the boat from past attempts by salties to get aboard. He reckoned that the bigger the croc, the more likely it was to work out where all these blueys were coming from. "Time to move" he said, and I wasn't gonna argue....
Iv'e fished a few mangrove swamps on foot,and the possibility of crocs really sharpens up your awareness and fieldcraft. Fished a few jungle streams in big cat country too, and that keeps one on alert also.
