Our Vision
Our vision is a world where orangutans are free from the threat of extinction and can live in the wild, unharmed by humans.
back to their home.
our two sanctuaries.
The Problem
There are numerous threats to the viability of the remaining wild orangutan population in Indonesia and Malaysia. The primary threat is the loss of habitat with up to 80% of suitable forest in Indonesia and Malaysia having been lost in the past 20 years. Other threats, which often go hand-in-hand with the destruction of the rainforest, are the illegal pet trade and poaching.

Happy World #RedheadDay!
Today, we invite all redheads—and everyone connected to a redhead—to join "Ranga and the Redhead Revolution".
This beautifully illustrated children's book by author Rachel Paget tells the story of Rachie, a girl who has always been teased for her fiery red hair, earning her the nickname 'Ranga'. However, when she discovers that #orangutans—the original 'Rangas'—are on the verge of extinction, she decides to reclaim the name and fight for a cause greater than herself.
The book is a heartfelt reminder that when we inspire others with our unwavering passion, we can become a powerful force for change in saving the critically #endangered orangutans and their #rainforest homes.
#Join the revolution! Kicking off today, the book will be sold internationally via Amazon for just AUD $13.20 per paperback. For a limited time, 100% of profits will go directly to BOS Australia to support our vital orangutan #conservation work.

New life for Jumbo ❤️🦧
So glad for Jumbo and all his friends.

🥰🥰🥰
In line with this year's motto for International Day For Biological Diversity—"Harmony with Nature and Sustainable Development"—let's reaffirm our commitment to protecting and conserving the rich diversity of life on Earth.
As a keystone species, #orangutans are integral to the health of the tropical forest #ecosystems they inhabit. They play a crucial role in seed dispersal by consuming a wide variety of fruits, managing to ingest seeds larger than those taken by most other frugivores, and travelling long distances while depositing these seeds.
By protecting orangutans in their natural #habitats, we safeguard countless other species of plants and animals, ensuring a #sustainable future for generations to come.
