Bruny Island - Geography

Geography

Geologically, Bruny Island is actually two land masses - North Bruny and South Bruny - that are joined by a long, narrow sandy isthmus. The holiday village of Dennes Point is located in North Bruny, while South Bruny is the site of the towns of Alonnah, Adventure Bay and Lunawanna.

Outside its settlements the island is covered in grazing fields and large tracts of dry eucalyptus forest. Inland forests continue to be logged, but other large sections - mostly along the southeastern coast - are preserved as the South Bruny National Park. While the seaward side of the island features two long beaches - Adventure Bay and Cloudy Bay - it is for the most part extremely rugged, with cliffs of dolerite that are over 200 metres above sea level. Bruny's channel side is far more sheltered and a favourite fishing and recreational boating area for local and interstate visitors.

Access to the island is by vehicular ferry, funded by the State Government. Since 1954, four vessels have operated the Bruny Island Ferry service between the island and Kettering on the mainland. The service is currently plied by the Mirambeena, which is unusual for using a Voith-Schneider propulsion system rather than a conventional propeller.

The d'Entrecastaux Channel region, sheltered by Bruny Island, is increasingly subject to foreshore erosion, some areas have begun sandbagging to reduce the effects.

    At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.
