As an Aussie, I can say the trope of “everything wants you dead” is highly overhyped. I’ve seen three venomous snakes in the wild in my life (and I’ve mostly lived in rural areas) and there’s a couple of venomous spiders, but none that will kill you (unless you’re very young, very old, or very sick). Blue-ringed octopuses, crocodiles and sharks exist, but rarely cause human deaths. You know what we don’t have? Bears. Alligators. Cougars. Wolves. Very few carnivores trying to eat humans here, it’s mostly creatures with excellent self-defense mechanisms.
