IIRC, I read an article that says the biggest predator of young salties is older salties- hunting the bigger ones for skin gave a lot of young 'uns a chance to survive a little longer. Then all of a sudden the hunting ban came in- and a LOT of young adult salties had the chance to grow bigger with no threats. Result: there are a lot more big adult salties out there than there ever used to be, and they have been roaming further afield than ever before.
Being salt-water adapted, they are starting to head out to sea...
Of course, I have an entire planet between me and Oz, so if the above is incorrect, let me know and I'll delete it.
