Investigator Group
The Investigator Group is an archipelago in South Australia that consists of Flinders Island and five island groups located off the western coast of the Eyre Peninsula. It is named after HMS Investigator by her commander, Matthew Flinders when he explored the area in 1802. The Group lies within the Great Australian Bight. All the islands except Flinders Island, and a part of Pearson Island, are within the Investigator Group Wilderness Protection Area and the Waldegrave Islands Conservation Park.
The Investigator Group is a group of islands and associated landforms that are located within an area extending for a distance of about 70 kilometres (38 nmi) south west from Cape Finniss on the west coast of Eyre Peninsula in South Australia. The group consists of the following islands and island groups placed in order of increasing distance from Cape Finniss: the Waldegrave Islands, The Watchers, Flinders Island, Topgallant Islands, the Ward Islands and the Pearson Isles.
The northernmost group lies 3 km offshore near the small town of Elliston. It consists of Waldegrave (292 ha) and Little Waldegrave (32 ha) Islands. They have calcarenite soils and were grazed by sheep until 1967. The vegetation is mainly regenerating pasture, with patches of native shrubland dominated by Native Juniper and Coast Daisy-bush.
The Watchers are a pair of rocks that are spaced about 1.9 kilometres (1 nmi) apart and which are located about 3.1 kilometres (1.7 nmi) west of Little Waldegrave Island. The western rock has a charted height of 7 metres (23 feet) and is reported in another source as being 7.3 metres (24 feet). The eastern rock is charted as an intertidal reef.
Flinders Island, which is 28 km offshore and at 36 km2 is the largest island in the Investigator Group. Flinders Island is leasehold land used for grazing. It has sandy, calcarenite soils, is mainly vegetated with pasture grasses, and has some remnant patches of heathland and Melaleuca woodland.
Topgallant Islands are located 6 km to the east of Flinders Islands and is a small island with steep cliffs and some stunted shrubland.
Ward Islands are located 16 km to the west of Flinders Island and is covered with shrubland and heathland.
The southernmost group consists of Pearson Island (213 ha), the Veteran Isles (14 ha) and Dorothee Island (56 ha). Pearson Island, the second largest of the whole Investigator Group, and containing its highest point at 231 m above sea level, is vegetated with shrub and heathland with patches of Casuarina and Melaleuca woodland. The Veteran Isles support low shrubland dominated by Twiggy Daisy-bush and Marsh Saltbush. Lying 3 km south-south-west of the Veteran Isles is Dorothee Island, the most southerly of the Investigator Group.
