Pacific Oceania

Pacific Oceania is the name given to the group of small nations of the Southern, Southwestern, Central and Western Pacific Ocean that compete collectively as one country in both the Davis Cup and Billie Jean King Cup tennis tournaments. Pacific Oceania is governed by the Oceania Tennis Federation.
As some Pacific Ocean countries and territories were too small or underdeveloped to have their own national teams, Pacific Oceania was established in the 1995, with both the men's and women's teams first participating in the 1995 editions of the Davis Cup and Fed Cup, respectively.
