I mean, you realise bugs exist everywhere though right? If you just don't like the big ones then stay out of the top end of the country and you'll be fine. You're more likely to have a bird try to steal your lunch than encounter something scary.

I think a lot of Australians are just unbothered about it as well, we kinda just exist together. When I was a kid my dad would often play with huntsmans, let them crawl over his face. They're pretty chill.
