The Australia women's national basketball team, nicknamed the Opals after the brightly coloured gemstone common to the country, represents Australia in international basketball. From 1994 onwards, the Opals have been consistently competitive and successful having won nine medals at official FIBA international tournaments, highlighted by a gold medal winning performance at the 2006 World Championship in Brazil. At the now-defunct regional Oceania Championship for Women, the Opals won 15 titles. In 2017, FIBA combined its Oceanian and Asian zones for official senior competitions; following this change, the Opals compete in the FIBA Women's Asia Cup.

Women's basketball is the team sport of basketball played by women. It was first played in 1892, one year after men's basketball, at Smith College in Massachusetts. It spread across the United States, in large parts via women's college competitions, and has since spread globally. As of 2020, basketball is one of the most popular and fastest growing sports in the world.
