Crocodylus porosus is most commonly found on the coasts of northern Australia, and the islands of New Guinea and Indonesia. It ranges west as far as the shores of Sri Lanka and eastern India, all along the shorelines and rivermouths of southeast Asia to central Vietnam, around Borneo and into the Philippines, and even out to Palau, Vanuatu, and the Solomon Islands. Saltwater Crocodiles are strong swimmers and can be found very far from land.
