Pearson Island is an island located in the Australian state of South Australia within the Pearson Isles an island group located in the larger group known as the Investigator Group about 63 kilometres (39 mi) southwest by west of Cape Finniss on the west coast of Eyre Peninsula. The group was discovered and named by Matthew Flinders on 13 February 1802. The island group has enjoyed protected area status since the 1960s and since 2011, it has been part of the Investigator Group Wilderness Protection Area. Pearson Island is notable both for its colony of Pearson Island rock-wallaby and for being a destination for scientific research.
Pearson Island is located about 63 kilometres (39 mi) south west by west of Cape Finniss and about 25 kilometres (16 mi) south west of Flinders Island. It is the largest of four islands that form the island group known as the Pearson Isles or the Pearson Islands.
It consists of one land mass with two relatively smaller peaks rising out of the sea in an arc extending to the south east via a spit of rock connected to its most southerly point. The arc encloses a bay known as “Anchorage Cove” which is sheltered from the weather both from the west and the south and which can be respectively used as an anchorage and as a landing point. The three parts of the island are informally referred to in one source respectively as the “north section”, the “middle section” and the “south section”. A unnamed rock which is permanently dry is located immediately west of the "south section" of Pearson Island.
The island has an area of 213 hectares (530 acres). Its highest point is a feature called “Hill 781” with a height of 238 metres (781 ft) above sea level and which is located in the south west end of the North section and which is named after its height in the imperial unit of measurement. “Hill 781” and two other hills, “North Hill” and “East Hill” on the “north section” are of a height greater than 200 metres (660 ft) while the highest point on the remainder of the island is “South Hill” on the “south section” with a height of 115 metres (377 ft).
