BIWA was established in 1974 by what is known as the Seven Fearless Sisters, an eclectic mix of Indonesian and foreign women who came together regularly to support each other as they faced the challenges of a developing society. Over the years the organization grew as its support network resonated with more women. The members did activities together and sought simple solutions to problems they shared. To raise funds they would sell the goods they made from their activities. Logically, they focused their charitable efforts on women who lacked the same access to society as men.

The concept of a money society came to Bali quite late. For years the Balinese conducted commerce through a barter system, which meant most jobs were related to the daily needs of life. There was less debt, more food and very little stress. The transition to a money culture has been difficult for an agrarian based society like Bali where the Subak system is the security of the banjar; a clear priority to please the Gods, the ancestors and the harmony of life.

Continuing these traditions in a modern capitalist economy has many challenges. BIWA has developed into a resource for women in Bali who have been left indigent as the result of the rapid changes of a modern society. BIWA helps women access what they need. Its social welfare efforts encompass health and education for women and children, assistance for HIV/AIDS prevention and rehabilitation programs as well as environmental projects and education.

BIWA is a secular, non-profit and non-political charity association for women from different nations and cultures residing in Bali. Its record of social welfare assistance is impressive, spanning more than four decades.
