Have your say on the future of our southern beaches

Mandurah's coastline is a key part of our identity. It gives us natural beauty, recreational opportunities, and economic benefits. However, coastal hazards such as rising sea levels, beach erosion, and severe storms regularly impact and change our beaches. To better manage these challenges, the City is creating Coastal Hazard Risk Management and Adaptation Plans (CHRMAPs).

A CHRMAP is a 100-year plan that aims to identify the impact of erosion, sea level rise and coastal flooding on both our beautiful coastline and the things we’ve built near it, such as parks, footpaths, and buildings. It will also investigate solutions so that the City can proactively manage these impacts if and when they do occur.

In 2023, a CHRMAP for the Northern Beaches was finished. Now, work has started on a Southern Beaches CHRMAP, which includes the ocean-facing coast from Roberts Point, Halls Head to Clifton.

The CHRMAP process involves:

  • Technical studies by coastal engineers
  • Input from the community through community surveys and workshops

Together, this information is combined to help us better understand potential erosion and flooding risks, and which assets might be affected by these events, so that we can identify and apply the best management options.

Get Involved

Our local community knows our beaches best, so your input is vital for the success of the CHRMAP and for shaping the future of our southern beaches. The Mandurah community still has two further opportunities to provide input into this very important document.



Stage 1 of the engagement is now closed.


Stage 1 of the CHRMAP Community Engagement was open from 1 August to 22 September 2024. Community members were able to provide input into the CHRMAP in three ways:

• Completing a short survey about values associated with our southern beaches.

• Using the Online Mapping Tool to share favourite spots and activities along the southern coast.

• Nominating to join the Coastal Community Reference Group (CCRG). CCRG members participated in Workshop 1 on 19 October 2024 to discuss values, uses and learn about key coastal hazard impacts possible along the coast. Workshop 2 & 3 will look in more detail at the options that could be considered and the decisions we make to manage them.

Stage 2 Community Engagement: Options Engagement

There are two options for engagement in Stage 2 of the CHRMAP’s engagement process: the ongoing work of the CCRG, and an external survey being undertaken by the University of Western Australia

The CCRG will participate in two workshops which will consider coastal management options for the entire southern beaches’ coastline, including the trade-offs that will need to be considered when deciding between the options available. The CCRG will meet on 8 and 22 February 2025.

The UWA Survey aims to understand preferences for managing the coastal environment and infrastructure at Falcon Bay in response to coastal hazards. Participants will be selected randomly through a recruitment marketing research firm. Although this is an external study, the outcomes will help with decision making for the CHRMAP. Any queries on this survey should be directed to UWA at: oceans@uwa.edu.au

Stage 3 Community Engagement: Draft CHRMAP

Once the CHRMAP has been drafted, community members will have the opportunity for formal comment on the document.

We value community input and encourage you to participate in our online surveys and Coastal Community Reference Group (CCRG) workshops. Your feedback will directly influence the CHRMAP.
