The Tonga women's national under-20 football team is the highest women's youth team of Tonga and is controlled by the Tonga Football Association.
Tonga's greatest football triumph to date was their triumph in the first ever Polynesian Cup held in 1993 over Samoa and the Cook Islands. Although local players have not yet made their mark on big leagues abroad, the Chief Executive of the Tonga Football Association, Joe Topou, was appointed to the FIFA Executive Committee in 2002. The Tonga association is the only sports organization on the island that employs full-time administrative staff.
Tonga's second Goal project will develop and improve the national football academy and the associations headquarters in Atele, Tongatapu, which was built in the country's first Goal project. This development work will ensure that all of the Tonga Football Associations needs are fully satisfied. Local matches will be held at the football academy, while the administration's requirements, including the needs of players, officials and spectators, will also be covered. The football school will be transformed into a House of Football.
