The Hideaway Island Post Office is world-unique and known as the earth's only underwater post office. Opened in May 2003, it is situated approximately three meters beneath the water's surface in the marine sanctuary off Hideaway Island in Mele Bay. The post office consists of a specialized fiberglass structure and is staffed during operating hours by professionally trained divers acting as postal clerks. Visitors can purchase waterproof postcards, have them validated underwater with a special embossing tool, and drop them directly into the mailbox. This mailbox is emptied daily, and cards are dispatched worldwide, making the post office one of the most visited attractions near the capital, Port Vila. Beyond its function as a curiosity, the underwater post office contributes to raising awareness for coral reef protection, as it is located in the midst of a bustling marine ecosystem valued by snorkelers and divers alike.
