This study supports work to identify, develop and implement flood mitigation options for the lower Maribyrnong River catchment.

The mitigation options will help to reduce overall risk from the possibility and consequences of a flood, while reflecting community values as much as possible.

Thanks for your feedback

Thanks for sharing your feedback on the long-list of flood mitigation options and the criteria used to evaluate them. Your input will help refine the options into a shortlist that will be assessed in detail, which we’ll seek your feedback on in the next phase of this study.

We’re now preparing a summary of what we heard, which we’ll share with you in early 2026. To receive updates by email, including on upcoming opportunities to have your say, follow this webpage:

What happens next

Late 2025 to early 2026:

• We’ll seek your feedback on the engagement approach for Phase 2: what’s working or could be improved?
• The project team will review feedback collected and share a summary
• We’ll use the feedback and evaluation criteria to help shortlist flood mitigation options.

Early to mid 2026:

• Phase 3 begins
• Share the shortlist of flood mitigation options for community feedback

About the study

The study will investigate flood mitigation options which aim to support a reduction in future flood risk, and which prioritise the safety of communities in the catchment area.

Due to the size and diversity of the Maribyrnong River catchment, a number of options are likely to be identified. These might include options that could be implemented in the short and medium term (at least 5 years), and others which will take considerable time to implement (at least 10-15 years).
