Slate and elsewhere): turn your body sideways, to give a smaller profile and defend your precious internal organs from its claws. Keep your face away to protect it as well. Put a barrier in between you, even a large tree branch if you can find one. Walk away slowly – don’t run, as it will out-hop you, and kick as it goes. Yikes! I think I’ll stick with my usual method of avoiding a kangaroo attack: don’t go near a kangaroo.
