Help us re-establish Adelaide's lost shellfish reefs by letting us know where along the Adelaide metropolitan coastline to build a reef.
What’s being decided?
Shellfish reefs once characterised the sheltered nearshore areas of South Australia. However, from the late 1800s to mid-1900s these reefs suffered from the impact of overfishing, dredging, water pollution and disease. Aside from the recently completed Windara Reef off the coast of Ardrossan on the Yorke Peninsula, native oyster reefs are now absent from South Australia’s waters.
Shellfish reef habitats are important to the marine environment, fish breeding, and water quality. They also provide recreational and economic opportunities to the state.
To help the environment and continue to boost the state’s economy, we will be constructing a second shellfish reef for Adelaide metropolitan waters in the Gulf St Vincent, expected to be completed by late 2020.
The proposed locations tab shows a map with three suitable locations we have identified where the reef could be built. These locations are within 2 km off the coast of:
- Glenelg, between Glenelg jetty and West Beach boat ramp.
- O’Sullivan Beach, between Christies Beach and O’Sullivan Beach boat ramp.
- Port Noarlunga, between Port Noarlunga jetty and Onkaparinga River mouth (within Encounter Marine Park Port Noarlunga Sanctuary Zone)
The background section provides further detail on how shellfish reefs are constructed, why we need more of them and how the proposed locations were identified.
How can your input influence the decision?
Your feedback will inform where South Australia’s metropolitan shellfish reef will be located.
What are the next steps?
The final location to build South Australia’s next shellfish reef will be guided by public feedback received through this consultation.
A feedback report will be available via this website following the consultation.
