Willis Island is indeed a remote and tiny island primarily used for meteorological purposes. It serves as an essential site for weather monitoring and observations in the Coral Sea region, but it is not a tourist destination due to its small size and restricted access. Visitors typically do not have the opportunity to set foot on the island itself, as it is primarily occupied by personnel from the Australian Bureau of Meteorology who are responsible for maintaining the weather station and collecting meteorological data. While it may not be a tourist attraction, Willis Island plays a crucial role in providing valuable weather information for the region.
