The Borneo Orangutan Survival Foundation (BOS) is a not-for-profit foundation supported by thirteen sister organizations around the world. (Until the recent name change, BOS was also known as the Balikpapan Orangutan Survival Foundation). BOS works under an official agreement with the Indonesian Ministry of Forestry for the conservation of orangutans and their ecosystem by involving and educating the local people. BOS is presently running the world's largest primate conservation project and employs more than 200 permanent staff. BOS' interests cover biodiversity issues (flora and fauna), forest rehabilitation, forest inventory and monitoring (through its company PT SarVision Indonesia), agroforestry (to improve local peoples' welfare and education), as well as working with orangutans and other protected wildlife.

BOS was formed in 1991 when Dr Willie Smits, a tropical forest ecologist and senior advisor to the Minister of Forestry of Indonesia, found a sick orangutan in the local market. He managed to keep her alive and was then given a second problematic baby, and had to care for the two of them.

The foundation has a board of directors, supervised by Ir. Djamaludin Suryohadikusumo, former Minister of Forestry of the Republic of Indonesia, who is also the patron of the foundation. The board of directors is assisted by a scientific advisory board, which comprises orangutan experts and other specialists from Indonesia and around the world.

Since its incorporation BOS has achieved an enviable track record of success. It has purchased thousands of acres of land to become eternal nature reserves owned by BOS, assisted in the confiscation of more than one thousand orangutans with their subsequent reintroduction into the wild, and by educated and provided livelihoods for thousands of local people.

In Australia, BOS Australia has been raising funds since 2001. Since this time thousands of dollars have been sent back to the various projects due to the generosity of the BOS donars and the dilligent work of the BOS volunteers. BOS Australia aims to support the BOS's activities in Borneo through:

• Fundraising
• Raising public awareness
• Education programmes

BOS Australia has DGR status with donations over $2 tax deductible for Australian tax-payers.
