Wind ... I was born in Australia Adelaide to be precise and never in the time I was a toddler did my parents put shoes on me while I ran around our garden so clearly they were never worried about snakes and spiders ... my aunt still lives out there and she has never mentioned snakes or spiders ... the reason why is it’s like us having rats they are all around us but how often are we bit by one ? The storms out there are amazing quite like a show at times and the rain wow ! And the roads are very wide and yes they drive on the same side as here .
