From the director of Wolf Creek, we have a 2007 horror film Rogue, also known as Territory. In Australian outback, bunch of tourists take a river boat ride to see the views and some crocodiles too. On their way back, they see a distress signal and follow it. After finding the remains of its sender's boat, they are attacked by very big crocodile and are stranded on a small islet in the middle of the river. With the tide rising, they are forced to confront the croc on its own territory.
