Southport Lagoon Conservation Area

Peaceful remote area with historical and botanical importance.

Southport Lagoon Conservation Area is a large portion of land and shallow expanse of water located on the south-east coast of Tasmania,

Found in the Huon Valley’s Far South between Southport and Recherche Bay this peaceful and remote area has been set aside for its significant history and botanical importance.

Southport Lagoon is 1060 hectares in size enclosed by a spit, with one narrow channel opening to the ocean with an extensive intertidal zone that is exposed at low tide.  Just a little further to the South is Blackswan lagoon also enclosed by a spit and covering a further 50 hectares.

Southport Lagoon was part of the large territory of the South Eastern Tribe of Aboriginals attracted particularly in summer to the nearby seal colony.

In the late 18th century and early 19th century, English and French scientists visited this area to collect and identify a large portion of Australia’s native flora for the first time.

In 1835 a large convict transporter, George III struck a reef directly offshore of the lagoon becoming Tasmania’s third worst maritime accident. As many as 128 convicts, three children, a soldiers wife and two crew members drowned. This tragedy has been recognised by a monument on Southport bluff to the north of the lagoon entrance.

Natural conservation values

The conservation area is considered significantly important for conserving endangered venerable and rare plant and animal species. It contains large areas of relatively undisturbed coastal heathland, one of the most threatened plant communities in Australia.

Many bird species are present only seasonally, such as black ducks, black swans and crested terns which are prevalent in summer. In winter you find pacific gulls and hoary-headed grebes.
