The Broulee Island Nature Reserve is a protected nature reserve located on the south coast of New South Wales, Australia. The 43 ha reserve was created in 1972 and is managed by the NSW National Parks & Wildlife Service. The reserve is situated 23 kilometres (14 mi) south of Batemans Bay and is adjacent to the village of Broulee. In the 1920s, there was a small port here from which a large amount of shellgrit was taken to Sydney, where they were made of lime and used in construction.
