4. Nauru
Nauru is likewise situated in the South Pacific Ocean. This country is much littler and has just 21 sq km (8 sq mi) of land. Nauru accomplished its freedom in 1969 and was in the past known as Pleasant Island. Amidst a century ago the island was one of the wealthiest places on Earth. It contained critical stores of phosphate. Be that as it may, the average assets are gone, and Nauru is frantically destitute today. The nation fundamentally relies upon Australian help. Australia is utilising the island as a detainment place for displaced people.
