Be Crocodile Safe In The Kimberley

First of all: always, always observe crocodile warning signs!
Don't assume it's safe to swim if there is no sign! Crocodiles attack out of deep, still or muddy waters, where they can't be seen. Always stay well away from those.
Small creeks, waterfalls, rock pools etc. are usually fine, but if you're not sure stay out of the water. Ask first! Either the locals or the next Kimberley tourist information centre.
