The kids were playing by the garage a few days ago with a couple of their friends when one of them spotted a snake. None of them could be sure whether it had legs just that it had disappeared inside the garage.
Australia is home to a lot of deadly snakes (they spotted a Brown Snake at the kid's school last year) so you can never be sure. The next day though I spotted this blue tongue lizard sunning itself by a hole in the fence so the mystery was solved. Blue tongue lizards are quite large (this one was about 10 inches long) but they're harmless and eat insects and berries.
