As a matter of fact, honey isn't just low in moisture, it's what's known as hygroscopic, meaning it actively sucks water out of anything it comes in contact with. That's why bacteria can't survive in honey: it desiccates them.

That's also why honey will eventually go bad if you leave it unsealed: it sucks water out of the air until it loses its hygroscopicity, at which point bacteria can survive in it.
