It’s not every day that one can find land not claimed by an existing country.

South Maudlandia, an Antarctic-based micronation, has laid claim to the territory since 18 March 2015 as the Autonomous Region of Pannonia. Another micronation project called Paraduin has also already staked out a claim at the same area, and the author also mentions Liberland in the project blog. -- Wikipedia
