Seal Island, also known as Seal Rock, is an island located in Encounter Bay off the south coast of Fleurieu Peninsula in South Australia approximately 2.7 kilometres (1.7 miles) south-east of Victor Harbor. Since 1979, it has been part of the West Island Conservation Park.


Seal Island is located about 2.7 kilometres (1.7 miles) south-east of Victor Harbor and 3.7 kilometres (2.3 miles) east-north east of Rosetta Head (also known as The Bluff). The island is described as being ‘a 1 hectare (2.5 acres) mound of tumbled granite bounders scoured of soil’ that ‘reaches 12 m above sea level’.[1] The island is also known as Seal Rock.[2]

Flora and fauna[edit]

As of 1996, Seal Island was observed as having no vegetation while the only vertebrate animals observed was a breeding colony of Silver gulls.[1]


The island's name is reported as suggesting the presence of an Australian sea lion or a New Zealand fur-seal colony on the island during the early 19th century.[1]

Protected areas status[edit]

Since 1979, Seal Island has been part of the West Island Conservation Park.[3] Since 2012, the waters surrounding its shores are located within the boundaries of the Encounter Marine Park.[4]
