A "dunny door" refers to the door of a dunny, which is an Australian term for an outdoor toilet or restroom. Typically found in rural areas, these toilets are often simple structures that provide basic sanitation facilities. The dunny door serves as the entrance, offering privacy for users. Dunny doors can vary in design, but they are usually made of wood or metal and may feature a latch or lock for security. In some cases, they are adorned with humorous signs or decorations, reflecting the quirky charm of Australian culture and its approach to outdoor facilities.
