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.

Groyne 1 Construction Update - 26 February 2021

Groyne construction works have been completed successfully and ahead of schedule with only minor works remaining including concrete path, kerbing, fencing and repairs. Temporary fencing will remain in place until completion of these works by 12 March 2021 after which time the area will be re-opened to the public.

Groyne 1 Construction Update - 10 February 2021

Construction works for the maintenance and upgrade of the Groyne 1 structure commenced on 1 February 2021. Existing limestone armour has been stripped off the structure and stockpiled for re-use and additional rock is now being brought to site with works currently focusing around the construction of the seaward section of the groyne. All works are expected to be completed by the end of March 2021 subject to continued suitable weather conditions.

All efforts will be made to ensure the Quinns Beach carpark remains open to the public during the works with traffic management in place as required during delivery of groyne construction materials.
