Poseidon Undersea Resorts was a proposed chain of underwater five-star resorts that was first slated to open by September 2008. The first was to be located on a private island in Fiji. The project was to be the world's first permanent one-atmosphere seafloor structure.
It is currently under construction on Katafinga Island in Fiji. With a design concept in mind, Jones needed to find an appropriate location. To help find it, Jones offered a $10,000 reward for anybody that came up with the perfect location for the venture. After taking the suggestion of a business associate, who recommended a reef off of Eleuthera, an island in the Bahamas, negotiations began with the island's American owners. The negotiations did not go well, and after a year of failed back-and-forth offers the location was scrapped and sights were set on Fiji. A deal was made with the owner of a privately owned 225-acre (0.91 km2) South Pacific Island located in northeastern Fiji.
