Historical connections
From the time Captain Cook sailed over the Antarctic Circle and then called
into Adventure Bay on Bruny Island, Hobart has been the gateway for many of
the explorers engaged in Antarctic exploration.
France's Dumont d'Urville, England's James Clark Ross, Norway's Carsten
Borchgrevink and Roald Amundsen and Australia's Douglas Mawson all
left their mark on Hobart as they passed through on their way to Antarctica.
The announcement to the world of Amundsen's success as the first man to
reach the geographic South Pole was made from the steps of the Hobart
GPO while his vessel Fram was moored in the Derwent River. Tasmania's
own physicist, Louis Bernacchi, was the first Australian to over-winter in Antarctica.

of the Antarctic can be found under Antarctic gateway.

Gondwana connections
The geophysical Tasmanian-Antarctic connection
Tasmania's connection with Antarctica pre-dates historical records.
About 50 million years ago, Australia and Antarctica were joined together
and formed part of the supercontinent called Gondwana. At the time,
Antarctica was not glaciated and the continent was fully vegetated.
As Australia separated from Antarctica, the Antarctic Circumpolar Current
evolved and Antarctica became glaciated, resulting in the extinction of
plants and animals. Only mosses, lichens, liverworts and some small invertebrates remained.
As one of the last land masses to break away from the Gondwana super continent,
Tasmania's geology bears a strong similarity to geological formations found in Antarctica.

The clear link between Tasmania and Antarctica can also be seen in the dolerite
rock, which does not occur on mainland Australia but is identical to that found
in the Transantarctic Mountains and the Prince Charles Mountains in eastern Antarctica.
Dolerite rock makes up several well-known Tasmanian features such as the Organ
Pipes of Mt Wellington, the Walls of Jerusalem, the Western Tiers and the top of Cradle Mountain.
More detailed information on Tasmania's unique geophysical connection with
Antarctica can be found on the Antarctic Gateway portal.

Tasmanian Flora
The remains of many plant species, now unique and endemic to Tasmania,
can be found in the fossil record throughout Antarctica.
Many of these 'Tasmanian' species have long since vanished from the
Antarctic continent, but related species still exist, in particular
Nothofagus gunnii, the endemic Tasmanian deciduous Beech, which is
still found in the temperate rain forests of Tasmania.
Other modern day plant species relatives now only found in
Tasmania include Man Ferns (Dicksonia antarctica), Myrtle
(Nothofagus cunninghamii), Creeping pine (Microcachrys tetragona),
Huon pine (Lagarostrobus franklinii), and Celery top pine (Phyllocadus aspleniifolius).

Tasmanian Fauna
Many of the birds and mammals encountered by Antarctic expeditioners can
also be found along Tasmania's coasts or in its offshore waters.
Some of these species, such as the southern right whale and Macquarie
Island's fur and elephant seals, had an enormous influence on the economic
development and history of Tasmania, and were instrumental in the discovery
and exploration of Antarctica and the Southern Ocean.
Seals and sea lions are also common in Tasmanian waters, and Antarctic
species make an occasional appearance. In recent years, elephant seals have
hauled out just 80 kilometres (50 miles) south of Hobart.

Magnificent seabirds such as the royal and wandering albatrosses
can be sighted off the Tasmanian coast from winter to early spring, while
dolphins, porpoises and orcas are common sights for expeditioners travelling south from Hobart.
Residents of Tasmania's east coast are also able to regularly see humpback
and southern right whales migrating north to warmer breeding areas during
the winter months, from May to late July, and travelling back to their feeding
grounds in the Antarctic and sub-Antarctic in August, September and October.

Tasmania's sub-Antarctic Island - Macquarie Island
A sub-Antarctic speck halfway between Tasmania's main island and
the Antarctic continent, Macquarie Island is located some 1467
kilometres (909.5 miles) south-southeast of Hobart and 1296 kilometres
(803.5 miles) north of the continent.
Macquarie Island has ecological significance that is
in inverse proportion to its tiny size. It is a haven for a variety
of furred, finned or feathered creatures and hosts some species such
as the royal penguin (Eudyptes schlegeli), which breed nowhere else in the world.
Although exploited during the 19th century, Macquarie Island has
been a wildlife sanctuary since 1933. Now, with its abundant wildlife
and unique geology, Macquarie Island is a place of unprecedented natural
significance and is proudly listed as Tasmania's second World Heritage Area.

Although Macquarie Island, at 54° 62' S, is close to the Antarctic
Convergence, it is legally part of Tasmania. As such, it is a protected
State Reserve managed by the Tasmanian Parks and Wildlife Service with
logistic and other support provided by the Australian Antarctic Division.

can be found under Antarctic gateway.
