About

​​​​​

​​​​​The Port Davey area is known as one of Tasmania’s most spectacular places.  Its waters are protected by the Port Davey Marine Reserve. The surrounding land area is protected by the Southwest National Park.  Both are part of the Tasmanian Wilderness World Heritage Area.

​The marine reserve protects a unique underwater landscape.  It is created by the deep layer of dark, tannin-rich freshwater which overlies tidal saltwater. The tannins in the water limit the amount of sunlight penetration to the top few metres, limiting the growth of marine plants. In their place lives a diverse collection of marine invertebrates. 

​The reserve is a mix of restricted and no-take zones.  There are also areas where diving and anchoring ​are not permitted. ​​​​
