Alliance of Girls' Schools Australasia

The Alliance of Girls' Schools Australasia (abbreviated as AGSA) is a non-profit organisation that promotes the education of girls in single-sex girls' schools, and promotes the image of, and support the development of, girls' schools in Australasia.

The Alliance's first annual general meeting was held in May 1996, where membership of the Alliance was extended to all girls' schools in Australia and New Zealand whether independent, government or Catholic. The Alliance was incorporated 18 August 1997.

The alliance currently accepts membership from any school in Australia, Hong Kong, Japan, New Zealand, the Philippines, Singapore, South Africa and Zimbabwe which educates girls only.

It is affiliated with the Girls' Schools Association (GSA, UK) and the International Coalition of Girls' Schools (ICGS, US).

In 2022, AGSA agreed to merge with the International Coalition of Girls' Schools. The combined organization will include over 500 schools in 18 countries that enroll over 300,000 students. AGSA plans to fully adopt the International Coalition of Girls' Schools name in November 2023.
