From this story in Adelaide Now:
A MONSTER 6.5m crocodile had to be killed by locals in a remote Northern Territory Aborigine community because it was killing their cattle. Jeida Francis, 23, said the croc was caught in Manangoora, an outstation 56km east of Borroloola. “It was massive. There were three huge ones out there. One of them is still out there at the moment.”


“It is pretty well fed,” he said of the dead saltie. “It took two LandCruisers to pull it out. They have one croc that is still out there. He should be getting to this size by now.” Mr Francis said he spent his childhood growing up with the predators. “We used to get dugong bones to feed them, to keep them from feeding on our goats … this one was getting too nasty and too close. It was attacking our cattle.”

OK, so what’s the minimum-sized boat you’d feel safe fishing out of around something this size? Sixteen foot? Eighteen foot? The battleship Missouri?
