Cherrybrook is located in the northern suburbs of Sydney (Australia) on the edge of the Berowra Valley Regional Park in the Hornsby Shire. The Brigade is operated by dedicated volunteers who provide a 24/7 fire protection service to the community.  The Brigade forms part of the Hornsby Ku-ring-gai District of the Greater Sydney Region of the NSW Rural Fire Service (RFS).

The primary function of the brigade is to protect life and property from fires, as well as promoting fire safety and providing support to other emergency services and the local community. 

We are skilled, well equipped and motivated volunteer firefighters who specialise in providing assistance across a wide spectrum of emergencies including bushfires, building fires, structure fires, motor vehicle accidents, as well as providing a valuable support role to our local full time Fire and Rescue NSW stations at Castle Hill and Beecroft. We also provide assistance to other emergency organisations as required to assist them in their operations such as storm and flood recovery. 

Rural Fire Brigades within the State of New South Wales come under the umbrella of the NSW Rural Fire Service, who provide financial, operational and technical support. We are assisted by the Hornsby & Ku-ring-gai councils with the provision of building vehicle and equipment maintenance support.
