Answering the need for a full-service koala hospital

Our beloved koalas are facing an unprecedented crisis due to habitat loss, climate change, disease, urbanisation, and recent devastating bushfires. These iconic animals are in desperate need of care, recovery, and long-term protection. Back to the Bush Koalas, Ltd has been helping sick, injured, and orphaned koalas for over 6 years. Now we are a recognised not-for-profit entity in Upper Flagstone, Queensland. We plan to offer a full-service koala hospital able to take in sick and injured koalas 24 hours a day, 7 days a week. Services offered will be radiology, ultrasound, laboratory diagnostics, and surgical services for koalas in the Toowoomba, Lockyer Valley, Granite Belt, and Somerset regions. Since 2019, this property has been used for rehabilitating orphaned, sick, and injured koalas. Since we began, we have helped over 60 orphaned or injured koalas successfully be released into the wild.
