 because of its importance as a breeding site for seabirds.

Climate

Because the island is so far south and is influenced by circumpolar weather systems, average temperatures are significantly colder than most of Australia. Maatsuyker Island temperatures are around 10 degrees all year with days being cooler and milder. Wind is usually constant. Due to the high vegetation in patches on the top of the island, it is possible to shelter on the "jeep trail" that runs from the lighthouse to the landing. Several vehicles have been used here over the years, including Suzuki Sierras in the 1980s.

Flora and fauna

The vegetation is dominated by the woody shrub Leptospermum scoparium

 was the last Australian lighthouse still being officially operated by lightkeepers. A second, smaller and automated lighthouse was installed in 1996 but it is unclear whether volunteers are going to continue to work the lights on Maatsuyker Island.

The lighthouse is located near the south west tip of Maatsuyker Island, probably because its main function originally would have been to warn ships approaching from the west and being blown in an easterly direction by the prevailing westerly winds of the Roaring Forties

The Roaring Forties is the name given to strong westerly winds found in the Southern Hemisphere, generally between the latitudes of 40 and 49 degrees. Air displaced from the Equator towards the South Pole, which travels close to the surface between the latitudes of 30 and 60 degrees south, combines...
