Vanuatu Post, Vanuatu
Vanuatu Post has created an official Post Office with a difference: It is the worldâs first Underwater Post Office. Situated within the Hideaway Island marine sanctuary, the Post Office sits in around three metres of water and both divers and snorkellers are able to post special âwaterproof postcardsâ. Visitors know that the post office is open for business when a flag is flown at the surface.
