By far the largest island in the group, at about 10 km2 in area, is
Wedge Island. The others are North Island, South West Rock and Peaked Rocks. Except for Wedge Island, the group constitutes the
Gambier Islands Conservation Park. Wedge Island is partly
crown land and partly privately owned; it was used for farming for 130 years following European settlement of the region, and holds several buildings, mainly used as tourist accommodation, an
airstrip,
pier and a
lighthouse. The waters around the islands are extensively used for
commercial and
recreational fishing and for
recreational diving. ==Wildlife==
