Adelaide Dolphin Sanctuary

Adelaide Dolphin Sanctuary is a marine protected area in the Australian state of South Australia located on the east coast of Gulf St Vincent in and adjoining the north-western part of the Adelaide metropolitan area and which was established in 2005 for the protection of a resident population of Indo-Pacific bottlenose dolphins ("Tursiops aduncus").
The sanctuary covers an area of coastline extending from Port Gawler in the north to North Haven in the south, and includes the waterways of the Port Adelaide River, the Barker Inlet and some associated channels, as well as Torrens and Garden Islands, and inlets on the Lefevre Peninsula such as Mutton Cove. The habitat protected by the sanctuary consists of “mangroves, seagrass, saltmarsh, tidal flats, tidal creeks and estuarine rivers.” As of 2014, it covered an area of .
The sanctuary was proclaimed in 2005 for the purpose of achieving the following two objects:
(a) to protect the dolphin population of the Port Adelaide River estuary and Barker Inlet; and
(b) to protect the natural habitat of that population.
The sanctuary is also required to achieve the following six objectives:
(a) the protection of the dolphin population of the Port Adelaide River estuary and Barker Inlet from direct physical harm is to be maintained and improved;
 (b) the key habitat features in the Port Adelaide River estuary and Barker Inlet that are necessary to sustain the dolphin population are to be maintained, protected and restored;
 (c) water quality within the Port Adelaide River estuary and Barker Inlet should be improved to a level that sustains the ecological processes, environmental values and productive capacity of the Port Adelaide River estuary and Barker Inlet;
(d) the interests of the community are to be taken into account by recognising indigenous and other cultural, and historical, relationships with the Port Adelaide River estuary and Barker Inlet and surrounding areas, and by ensuring appropriate participation in processes associated with the management of the Port Adelaide River estuary and Barker Inlet;
 (e) public awareness of the importance of a healthy Port Adelaide River estuary and Barker Inlet to the economic, social and cultural prosperities of the local communities, and the community more generally, is to be promoted; 
 (f) the principles of ecological sustainable development in relation to the use and management of the Port Adelaide River estuary and Barker Inlet are to be promoted. 
As of June 2015, the Adelaide Dolphin Sanctuary was managed by the Department of Environment and Water with assistance from other South Australian government agencies, local government and other organizations with responsibilities in respect to the waters and land associated with the sanctuary or having an interest in such. Management activity was supported by a community volunteer group known as the ADS Action Group which was created in 2012 and which had 50 registered volunteers in 2015.
The Adelaide Dolphin Sanctuary shares territory with the following protected areas – the Barker Inlet-St Kilda Aquatic Reserve, the Port Gawler Conservation Park, the majority of the St Kilda – Chapman Creek Aquatic Reserve and the Torrens Island Conservation Park. It will also share territory with parts of the Adelaide International Bird Sanctuary yet to be proclaimed as of 27 October 2016 and which are located in localities and suburbs including Bolivar, Buckland Park, Dry Creek, Globe Derby Park, Port Gawler and St Kilda.
The sanctuary also adjoins the "Adelaide Metropolitan Beaches Restricted Area" which extends from North Haven in the north along the Adelaide metropolitan coastline to Sellicks Beach in the south and which is described in the "National Parks and Wildlife (Protected Animals—Marine Mammals) Regulations 2010". Both the sanctuary and the "Adelaide Metropolitan Beaches Restricted Area" are areas subject to the additional regulatory requirements regarding “commercial activities” in respect to interaction with marine mammals including all species of dolphins present in South Australia.
The sanctuary is classified as an IUCN Category VI protected area.
