Big Green Island, Nature reserve in Flinders Council, Australia
Big Green Island is a nature reserve located west of Flinders Island in Bass Strait, featuring granite formations, limestone outcrops, and native coastal vegetation across its protected area. The island spans 125 hectares and sits within the waters separating Tasmania from the Australian mainland.
The reserve was established on July 17, 1957 by Tasmania Parks and Wildlife Service to protect its ecological features and wildlife populations. This designation made it a significant refuge for native seabirds breeding in the Bass Strait region.
The island integrates conservation efforts with agricultural practices, maintaining a balance between environmental protection and sustainable land management in Tasmania.
Visitor access is restricted to protect the breeding seabirds, and permission is required before arriving at the island. It is best to contact the managing authorities in advance to understand access conditions and any required precautions.
The island hosts around 45,000 seabirds including shearwaters, penguins, Cape Barren geese, gulls, and terns that return to breed here regularly. This large congregation of breeding birds makes it one of the most important nesting colonies in Bass Strait.
