causing radio interference if you receive a call near an active speaker
Oh damn, this just bought a flood of memories back from nowhere. That distinct sound that would comee out of the speakers right before you got a call. I don't think I even noticed that it doesnt happen anymore.
These are perfectly harmless and live in colonies. Used to have these around growing up and let them crawl all over my hands. Most spiders in Australia are harmless, there's really only 2 or 3 types you need to worry about. Redback, funnel web and maybe white tip. The rest might hurt if they bite you, and of course an infection is possible if not cleaned but thats for any type of bite really.
