australia has deadly stingrays.
Yeah, but we have Paris Hilton, Lindsay Lohan, Britney Spears, Courtney Love, David Hasselhoff, ................
There are deadly and poisonous things, but they aren't everywhere...a stingray piercing your heart and killing you is a unbelievable fluke. I've never seen a stingray whilst swimming in the ocean, or a shark for that matter...and I've lived on surf beaches for 10 years of my life in my early twenties. I did see dolphins often and was metres away from them several times however.
I've only seen deadly spiders, but they are slow moving, and I've never been bothered by spiders.
I've seen a snake twice....and I fucking hate, HATE snakes. But that is it and neither were deadly.
I'd say the gun totin' crazies you have in the US are much more scarier than any shit we got going on down here...and let's face it, we were primarily colonised by Europeans...if the shit we have here was that deadly, they would have run their sorry pink asses away!
