Key Facts

The Mindarie Breakwater was constructed in 1988 and management responsibility was handed to the City of Wanneroo in 2005. Since this time the City has undertaken a number of technical investigations, monitoring, risk mitigation measures and minor maintenance works.

Phase 1 Maintenance works were undertaken in 2017/18 which focused on a 160m length of the Mindarie Breakwater which experienced significant wave overtopping and displacement of rock debris onto the road during storms. The completion of these works increased and widened the crest level of the structure resulting in less wave overtopping and associated safety issues.

The Mindarie Breakwater Maintenance Options Assessment and Detailed Design Study commenced in January 2019 and was recently completed in February 2022. The study included extensive local data collection, review of existing information, assessment of a range of breakwater maintenance options, detailed numerical and physical modelling and detailed design of the preferred option that addresses the current issues and design requirements of the breakwater for the next 50 years.

Future breakwater management works are currently scheduled to commence in October 2022 and will be staged over two financial years.
