Dempster Inlet is a pristine and remote tidal estuary system located within the Shire of Ravensthorpe in Western Australia. It forms part of the larger Fitzgerald River National Park, one of the most biologically significant areas in the region. The inlet is characterized by its wilderness setting, with an entirely uncleared catchment, and features expansive sandy dunal areas, beaches, and marshes. As a designated wilderness zone, it offers a unique, low-impact fishing experience for anglers seeking solitude and a connection with a largely untouched coastal environment.
