haha ye like the huntsman and funnelweb are pretty huge, about the size of your palm, but the huntsman is like not poisonous, the funnelweb is deadly ahah
but its not a spider your gonna find in your house. more common ones are like redback ones, they are pretty deadly too. but again, when i say common, ive only seen a redback once in my life! ahah, they are common in australia, but your not gonna find them in your homes/schools etc etc
