Asking for a friend: they (and I) have done some searching and the only humidity requirements we can find in the sheets refers specifically to egg incubators rather than the animals actual living space. The only clues i could find indicate that it would be wetter than a woma, as it occupies a "semi-tropical" region of northern Australia which, as you can imagine, encompasses a whole range of climates. I'm inclined to assume 60's to 70's.(but its not my snake so i'm a bit nonchalant) Anyone have a specific best practice??
