I’ve had a certain amount of fun telling people my snake story, and you’ll be relieved to hear that no-one has ever found a snake in their house. In the garage, yes; in the loft, yes; in the paddock, definitely yes; but in the house? No! Which suggests to me that it isn’t very common and that you’re unlikely to see one if you come and visit!
As I look out of the window now I can see a flock of wood ducks by the fence, and a couple of wallabies nibbling the grass about 20 metres away. Bucolic bliss; not a snake in sight.
