Macquarie Island environment
Macquarie Island is a subantarctic island located in the Southern Ocean at a latitude of 54° 30' south, 158° 57' east, approximately halfway between Antarctica and Australia.
It lies 1466 kilometres SSE of Tasmania and 1294 kilometres north of the Antarctic continent.
The island, or "Macca" as it is often called, is 34 kilometres long and five kilometres wide at its widest point. It is a Tasmanian Nature Reserve managed by the Tasmanian Parks and Wildlife Service.
The island lies just to the north of an oceanic boundary, the Antarctic Polar Frontal Zone or Antarctic Convergence, where cold polar water to the south meets the warmer subantarctic water to the north.
In good weather, it takes about three days to reach Macquarie Island from Hobart. Ships anchor in Buckles Bay to the east of the station. Ship-to-shore transport is via helicopter, amphibious vehicles called LARCs or inflatable rubber boats (IRBs).
