The Geographe Bay Catchment includes spectacular and diverse landscapes which are recognised internationally.
The Catchment is 200,000 hectares and surrounds the iconic Geographe Bay, spanning from Dalyellup to Bunker Bay, and inland from Kirup to Wilyabrup.
It is bounded by the Darling Range, the Whicher Range and the Leeuwin-Naturaliste Ridge. The southernmost part of the Swan Coastal Plain, extending south and west to Dunsborough, lays below these ridges.
Nestled in a biodiversity hotspot, our Catchment has a high number of rare and endemic plants and animals, and our waterways have significant ecological values, despite a history of modification for agriculture and urban development. Sixteen subcatchments flow into our most valued and iconic asset: Geographe Bay.
