The conservation park consists of two parts with the first extending from Clinton on Yorke Peninsula on the west side of Gulf St Vincent to Port Wakefield on the east side of the gulf and the second extending south of Port Wakefield to Sandy Point. The conservation park was originally proclaimed in 1970 as the Clinton National Park under the National Parks Act 1966, was re-proclaimed under the National Parks and Wildlife Act 1972. The area contained within the conservation park including the ‘head of gulf wetland and Wakefield River estuary’ is considered to be ‘important as a fish nursery and a significant site for migratory wading birds’.[2][5]
