Two guys in the last week have told me they have seen Tiger snakes SWIMMING in the Australind estuary while they have been scooping for crabs (the guys, not the snakes) Both in shallow water, one was near the shore, the other about 500 mtrs out on a shallow sandbar. I occasionally come across a dugite at work when I'm wearing jeans and workboots, but meeting a Tiger snake when you're only wearing boardies and a rashie and you are crotch deep in water
