It depends a lot in what part of Australia you go to. I live in the north east of NSW, and we have our share of snakes. We actually had a common Brown snake in our kitchen once. I had to kill it with a shovel because a shotgun would mess up the floor. We get regular visits from couple of Pythons, or carpet snakes that chew on the occasional bush rat. The fact is that we do have some of the most venomous snakes in the world here, but there are really very few fatalities from them. If they are not in or around the house I leave them alone. Most people who get bitten by a snake have either tried to kill them, or have stepped on them. You just watch where you put your feet in the bush and you'll be fine.
