Quinns Beach Long Term Coastal Management

The City has recently completed the following stages of major construction works along the Quinns Rocks coastline in accordance with the recommendations put forward in the Quinns Beach Long Term Coastal Management Study:

  • Stage 1 (2017/18) - Groyne 4, beach access ramp and beach renourishment.
  • Stage 2 (2018/19) - Extension of groyne 2 and beach renourishment.
  • Stage 3 (2019/20) - Extension of groyne 3 and beach renourishment.

These works were completed on time and within budget. The new and extended groyne structures are already showing benefits relating to the natural trapping of sand particularly to the south of the structures during summer conditions and a reduction in operational beach re-nourishment requirements (excluding recent impacts from extreme storm events over the 2020 winter season).

Groyne 1 Maintenance and Upgrade

The remaining existing groyne that has not been upgraded as part of the above works is the southern groyne (groyne 1 adjacent to Fred Stubbs Park and the Quinns Beach car park).

Lengthening of this structure was not required as part of the long term coastal management recommendations, but now requires significant maintenance works to improve public safety and ensure ongoing functionality of the structure into the future. The City will be conducting maintenance and upgrade works of the groyne 1 structure from January to April 2021. Funding for this project has been provided by the State Government’s WA Recovery Plan.
