I have to say: Australia is a beautiful country and I wouldn't mind visiting it, but I don't see how the residents live in such close proximity to so many very, very venomous snakes in their everyday lives. I'd be a complete mess. I hate snakes anyway, and seeing something like a brown snake in my garage would totally freak me out.
I've been told that the best business in Australia is that of snake removal and general critter catcher. I am not surprised. I imagine their services would be gratefully received and generously compensated! I know if I lived there and found any kind of snake in my house, I'd be willing to pay whatever the snake catcher wanted to get it *out!*
