International Lesbian Day is an annual day to celebrate and bring visibility to lesbians in the LGBT+ community. The purpose of the date is to celebrate and shine a light on the diversity of lesbians internationally. Whilst the exact foundation of International Lesbian Day is uncertain, it is widely believed that it began in Australia and New Zealand in 1980 when a Lesbian Day March was held in New Zealand. The first Australian event was held at the Collingwood Town Hall in Melbourne on October 13, 1990.
