Lake Wollumboola is a stunning 648-hectare (approximately 1,600 acres) coastal lagoon nestled in the Shoalhaven region of New South Wales, on Australia's South Coast. Situated immediately south of the town of Culburra Beach and north of Jervis Bay, the lake forms part of Jervis Bay National Park and offers a unique and productive fishing environment unlike most conventional estuaries in the region. One of its most defining characteristics is that it is an intermittently open coastal lagoon — separated from the ocean by a sand berm roughly 100 metres wide that only breaches naturally when lake levels rise above 2.5 metres above mean sea level. This intermittent connection to the ocean profoundly shapes the fish assemblages, water chemistry, and overall ecology of the lake, making it a fascinating and rewarding destination for anglers who appreciate wild, dynamic coastal fisheries.
