Sydenham Inlet, often referred to locally as "the lake," is a premier saltwater estuary system located near the town of Bemm River in East Gippsland, Victoria. This coastal inlet is a significant light tackle fishing destination, renowned for its accessibility and productive waters. The system is fed by the Bemm River from the west and the Little River from the east, and it stretches to meet Bass Strait. A defining characteristic of the inlet is its dynamic mouth, which can be open or closed depending on rainfall and seasonal conditions, significantly influencing water levels, salinity, and fish behavior within the estuary. While smaller than some neighboring systems, it offers a concentrated and diverse fishery that is approachable for visiting anglers.
