The City of Wanneroo encompasses an area of 685 square kilometres. The Two Rocks Volunteer Bush Fire Brigade provides a fire prevention and suppression service for the municipality with the exception of areas under the care and control of the Department of Biodiversity, Conservation & Attractions – Parks & Wildlife Service and the gazetted fire districts controlled by the WA Fire and Rescue Service.

The bush fire fighting area consists of coastal dunes and gently undulating sand country with numerous outcrops of limestone and caprock. The vegetation of the district includes large areas of pine plantations, swamps, heavy bush areas, heathland scrub & rural properties and buildings.

The Two RocksVolunteer Bush Fire Brigade consists of about 20 volunteer members who work rostered times 12 months of the year. Assistance is given to the WA Fire and Rescue Service and Parks & Wildlife Service when required. Over the years the brigade has, like many other volunteer fire brigades, met the needs of a changing community and fire service to develop into what is now an efficient and professional volunteer fire brigade which can go from mounting an attack on a bush or wildfire to attacking a structure fire.

The fire fighting fleet consists of 1 x 1.4 Rural Tanker and during the bush fire season a Light Tanker.
