Munna Point Groynes

Updated: Nov 25

Erosion at Munna Point caused loss of beaches and prompted the need for a sustainable solution. ICM designed and delivered a low-impact groyne system, complemented by dredging and nourishment, to stabilise the shoreline and restore recreational beach access.


Munna Point Groynes

 

Project Details 

  • Client: Noosa Shire Council 

  • Date: 2014-2018 

  • Location: Noosaville, Queensland, Australia 


 

About This Project 

The Challenge 

Munna Point experienced ongoing erosion, leading to the complete loss of beaches in some areas. Regular nourishment programs provided limited results and were eventually discontinued. The location, including the adjacent Noosa River Holiday Park (a Queensland Heritage site), required a solution that addressed aesthetic concerns, minimised environmental impacts, and preserved public access while ensuring long-term stability. 


The Solution 

ICM developed a tailored design comprising of seven low-crested groynes and a dredging and nourishment program to reinstate the foreshore beach. Key features of the solution included: 

  • Resilient Design: Conservative spacing of groynes to ensure stability and minimise future maintenance. 

  • Custom Geotextile Materials: Sand-filled geotextile mattress was used to mitigate risks of deepening at the groyne heads, ensuring long-term durability.

  • User-Friendly Design: Soft, sandy-colored geotextile containers maintained aesthetic harmony and ensured the groynes were safe and accessible for public use. 


The works were executed in two stages, with a comprehensive monitoring program to evaluate performance. Approvals from local council and state agencies were secured for each stage, including a formal monitoring program to track outcomes and minimise risks. 



“This project showcases how thoughtful design can balance shoreline stabilisation, environmental sustainability, and community needs. We’re proud to have delivered a solution that preserves Munna Point’s natural beauty and utility for years to come.” - International Coastal Management
