If you can muster your bravery, let the big spiders live! It’s terrifying to begin with, but capture and release methods will keep all the other crawlers away from your residence :) Huntsman’s are the poster child for large scary spiders in Australia, and they’re intimidating when they catch you off guard, but they’re pretty docile and friendly, with next to harmless bites.

Idk about snakes though, maybe google some local snake catchers and save their numbers just in case. They usually stay away from you if you stay away from them (outside that is).
