Australia is one of only five countries to have sent athletes to every Summer Olympics of the modern era, alongside Great Britain, France, Greece, and Switzerland.
These are the rosters of all participating teams at the women's water polo tournament at the 2020 Summer Olympics in Tokyo. The ten national teams were required to submit squads of 12 players. Additionally, teams could name one alternate player.
