Extent & description

Sleaford Bay is located on the south coast of Eyre Peninsula in South Australia about 21 kilometres (13 mi) south-west of the municipal seat of Port Lincoln.[1]

It lies between the headland of Cape Wiles at its western extremity and headland of Cape Tournefort at its eastern extremity. A subsidiary bay named Fishery Bay is located on its west side about 2 nautical miles (3.7 km; 2.3 mi) north of Cape Wiles.[4]

History

The bay was named after the town of Sleaford in Lincolnshire, England by the British navigator, Matthew Flinders in 1802.[2]

The bay also known respectively by local aboriginal people as Kuya Bidni by the “Sleaford Mere tribe (presumably Nauo)” and as Tannanna by "the Eyre Peninsula tribe (presumably Pankala)."[1] The Baudin expedition who visited after Flinders gave it two names – Baudin used the name Anse des Nerlans while Peron and Freycinet revised it to Baie Lavoisier after Baudin’s death.[1]

A whaling station located on the coastline within Fishery Bay was in operation from 1839 to 1841.[5]

Settlements and infrastructure

The coastline of Sleaford Bay is occupied by the locality of Sleaford in the west and by the locality of Lincoln National Park in the east.[1]

As of 2005, port infrastructure within the bay consisted of a boat ramp located in Fishery Bay.[6]

Proposed seawater desalination plant

In 2018, a proposal to construct a 3 gigalitre per year seawater desalination plant at Sleaford Bay was announced. Land was purchased in July and the project is expected to cost $80 million to complete.[7][8] The location is one of several prospects previously earmarked by SA Water in 2009.[9]

Protected area status

The Thorny Passage Marine Park occupies the full extent of the bay while the Lincoln National Park extents to Mean Low Water Mark on its eastern side.[10][11]
