Rapid Bay, South Australia


Rapid Bay is the name of both a locality including a small seaside town and a small bay on the west coast of the Fleurieu Peninsula, South Australia. It lies within the District Council of Yankalilla and its township is approximately 100 km south of the state capital, Adelaide. It is well known for its limestone quarry and its pair of jetties which are popular sites for recreational fishing, scuba diving and snorkelling.

History

Rapid Bay features in the creation myths of both the Kaurna and Ramindjeri people, most notably as the burial site of creation ancestor Tjilbruke's nephew.
South Australia Colonial Surveyor General Colonel William Light made his first landfall on mainland South Australia at Rapid Bay on 8 September 1836. The site was named after Light's ship, the 162 ton brig Rapid. To mark this historic landfall the Colonel's initials, "W.L.", were carved into a large boulder – a replica is visible in the township, while the original is stored in the South Australian Museum, in Adelaide. John Rapid Hoare, also named for the brig Rapid, was the first European child born on mainland South Australia. Claims that he was born at Rapid Bay have been refuted.
For a short time Rapid Bay was considered a potential site for the new state capital, but with the discovery of the Adelaide Plains it faded into quiet obscurity.
The Broken Hill Proprietary constructed the town, an ore-loading jetty and a high voltage power line from Willunga during the period 1938 to 1942 as part of the works undertaken to establish the limestone quarry. Mining commenced in 1942. The limestone was used as a flux in the company's steelworks at Whyalla in South Australia, and Newcastle and Port Kembla in New South Wales.
On 1 January 1982, ownership of the jetty was transferred to the Government of South Australia from BHP at no cost. The quarry was purchased by Adelaide Brighton Cement.

Attractions

Rapid Bay is known for its imposing cliffs, caves, beach, two jetties and artificial reefs. A resident leafy seadragon population inhabits the bay and weedy seadragons are also sometimes seen. It is considered to be one of Australia's premiere scuba diving sites, and has been listed featured on SportDiver as one of the world's top 9 dives. The ecological communities on the jetty pylons are well established and attract large schools of fish including Old Wives and Zebra Fish. At least 49 species of fish have been recorded in the vicinity of the Rapid Bay jetties. Giant Australian Cuttlefish and Blue-ringed octopus can also be found on the sea floor.
It is also a popular recreational fishing site, though the longer historic jetty is closed to fishermen due to its state of natural decay.

Jetties

BHP Jetty

The BHP Jetty was originally long, with a 'T' section of length for ship-loading. The jetty terminated in of water. Originally built by BHP and later operated by Adelaide Brighton Cement, the jetty ceased commercial operations in 1991. It suffered storm damage in 2004, after which it was progressively closed in stages for the purpose of ensuring public safety. Above the water, the jetty is slowly decaying and is off-limits to the general public. Below the water, the jetty provides habitat for a wide variety of temperate marine species. Since its closure, the above-water structure has also become an increasingly valuable roost for seabirds.

Public Jetty

Construction of a new jetty of length located east of the BHP jetty was completed in 2009 to replace the public amenity lost by the progressive closure of the BHP jetty.
The new jetty has since been colonised by marine life and augments the more established ecological communities on and around the historic jetty. At the seaward end, a staircase provides safe and easy entry to the water for divers and snorkellers. The jetty features concrete decking, is artificially lit after nightfall and is a popular spot for recreational fishing.
