We used to go to Guilderton as kids (it's about 110km north of Perth). The family had a holiday home up there. It had lots of bush around it and there were huntsman spiders in there. We would wake up at night and these 5-6 inch spiders would be crawling across the ceiling above us.With the spiders you have there, you're a brave man, I'm telling you. You ever see huntsman spiders in your house? I'd be outta there like a shot and never be able to return, even though I know they're harmless to me!
We got them in Perth too and they come in mainly during summer to escape the heat outside. You would chase them around and catch them in a bucket and take them outside. Sometimes they got stroppy (angry) and would rear up. You could see the venom dripping off their fangs.
