Nauru Island is the main (and only) island of the Republic of Nauru, a small island nation in Micronesia. It's a raised phosphate rock island surrounded by a coral reef. Think of it as a single island nation. ποΈ Unlike island groups, Nauru is just one island. It is geographically small. It has a unique history of phosphate mining and resettlement attempts. It's like a solitary entity in the vast Pacific.
