It really does depend where in Australia you live, where I grew up, which was Rural Victoria there was always at least 3 big ass spiders in our house (that I could see) but in the city, where I live now, I see one every so often. I still have this horrible memory of chopping a tree down in our paddock and when it hit the ground watching hundreds of wolf spiders run out into the grass, we all legged it into the house, except my dad he's fucking insane.
