I see on average about 6 snakes a week in my travels mostly carpet snakes and green tree snake which are harmless but I do see the odd eastern brown snake which kill you dead pretty quick. Its also considered the worlds 2nd most venomous land based snake. Not far from where I live we have also had quite a few fatal and non fatal shark attacks plus record sightings of large(5m+)great white sharks . Then yes you have spiders that you never see but you know are hiding somewhere ready to scare the crap out of you when you least expect it !!!
