Inner Sister Island - 2010
Inner (or West) Sister Island is only 1.9 km to the north of Flinders Island, yet it is not as accessible as one might expect upon just looking at a map. The passage between the island and Flinders is subject to very strong tidal rips and surges. The rough seas in the Passage known as the 'stone choppers' or 'stern choppers' make a crossing in a small boat perilous.
Inner Sister Island Survey
Inner Sister Island, at 748 hectares, is one of the largest of the approximately one hundred outer islands in the Furneaux Group in eastern Bass Strait. The island is about 5 km from west to east and 2.7 km north to south at its widest. The size, and geographic location of the island, together with government's joint management responsibility with a private lessee, was amongst the factors that made this island an ideal target of the Hamish Saunders Memorial Island Survey Program.
- In a survey of terrestrial mammals on the island, four of the five native mammals known to occur on the island were observed during this survey
- The first record was made of Tasmanian pademelons climbing and foraging in african boxthorns and other shrubs.
- A total of 28 fish species were identified from the underwater surveys and 68 mollusc species were identified from the beach wrack surveys.
- We observed and made observations on Whitelipped snake, Tiger snake, White's skink, Blotched bluetongue, Metallic skink, and Three-lined skink.
- A juvenile male stick insect was found at the eastern end of the island. This is believed to be the first record of a stick insect from the eastern Bass Strait islands.
