I had the volume off on the first one and did not realize there was sound...Going by the accent of the woman making the video, sounds more American to me. (I like the "oooh!" at the end) I don't believe there are any snakes here in Oz that are as sociable as those. Our most common one here in Queensland is the Eastern brown, that can stand right up on it's tail and launch itself at you. The other I saw once on a roadway was the Red belly, black snake.

I keep telling my kids I want to go to Australia (have wanted to since I was a kid). They keep telling me they won't go as everything there can kill you.
