Marine & coast

The Glenelg Hopkins region is characterised by its dramatic coastline, with towering cliffs and extensive dune systems carved out by changing sea levels, volcanic activity, and wind and water erosion. 

The marine and coastal environment of the Glenelg Hopkins region extends 220 km from South Australia east to just before the Bay of Islands. The marine environment extends out three nautical miles (5.6 km) to the state waters limit and covers about 142,360 ha.

The coastal environment considers all land five kilometres inland from the high water mark, or further to encompass the long estuaries such as Glenelg, Surry and Lake Yambuk.
