Extent

Vivonne Bay has been described in an American source as being "a bight in the coast" between Point Ellen in the west and the Eleanor River in the east which is referred to as being the ‘Mary River’ and which is located about north-northeast of Point Ellen. While the American source does nominate an eastern extremity, the official Australian source does not.


Depth

The depth of water within the bay is reported as being in the range of . The bay is reported as being suitable as an anchorage where there is a need to shelter from northerly and westerly winds. However, the bay is considered to be unsuitable as an anchorage in the case of "fresh SE winds" as "there is no space to get underway if the wind increases and a sea is raised."


Coastline

The bay’s coastline consists of a curved sandy beach of about in length with a western end relatively sheltered from wave action by Point Ellen and an eastern end that is subject to "higher wave energy" with the result of "well-developed offshore bars" being formed and the Eleanor River being "constricted due to the large volumes of marine-sourced sand" being recycled and trapped in its mouth. Point Ellen is described as being "a grassy mound 8.5m high" that is "bordered by low rocks at its base" and is formed of a "

The Harriet River has an estuary coastal lagoon system at its mouth due to the local absence of the "bedrock cliffs" that dominate Kangaroo Island’s coastline.

2011 drownings

Vivonne Bay is recognised as having a significant undertow and at times a sizeable swell, and is therefore suited only to experienced swimmers. In April 2011, two Australian tourists drowned when a large wave swept them out to sea as they posed for a photograph with their backs to the water at Point Ellen at the western end of the bay.


Fires

Vivonne Bay was impacted by bushfires in January 2020 which necessitated the evacuation of Vivonne Bay township and surrounding areas on Thursday 9 January 2020
