Macquarie Harbour is a vast, shallow fjord on Tasmania's wild west coast, covering approximately 260 to 315 square kilometers. It is Australia's second-largest harbour and is characterized by an average depth of 15 meters, with deeper areas reaching up to 50 meters. The harbour is a unique marine environment where saltwater and freshwater layers create distinct angling opportunities. Its entrance, known as Hell's Gates, is a narrow channel where the harbour meets the Southern Ocean, leading to the open coastline of Ocean Beach. The town of Strahan serves as the primary base for accessing the harbour, which offers a dramatic and remote setting for anglers seeking a variety of saltwater species amidst spectacular scenery.
