The Gellibrand River, located on the western side of Victoria's Otway Ranges, is a significant and valuable recreational fishery flowing through diverse landscapes before reaching the Southern Ocean near Princetown. This river system supports a rich native fish community and offers anglers a variety of experiences, from walking and fly fishing in its upper reaches to targeting estuary species near its mouth. The river is particularly renowned for its healthy populations of native blackfish, attracting substantial angling effort, and its estuary is noted for supporting some of the best blackfish populations in the state alongside several other unique native species.
