8 August 2025

From now until Sunday 24 August, you can share your past experiences of flooding in the area.

Your real-world knowledge will help to ensure the accuracy and quality of the flood maps being produced – confirming our predictions, or revealing new information to investigate.

Share your experiences online

Provide your feedback via the webpage for your council area:

How your input helps

The information you provide will be added to our existing data, as well as data from councils and the Department of Energy Environment and Climate Action (DEECA). This will be reviewed by our flood modelling experts, who will check this against their models and determine if further investigation is needed.

You’ll then have an opportunity to provide feedback on the updated maps before they’re finalised. For details on the process, refer to the diagram below.

Diagram of six steps in flood map development, from community input to updating emergency plans.
  1. Seek community experiences of past flooding and begin flood modelling (consultation period: 1-2 months)
  2. Peer review of model and preparation of flood maps (planning period 12-18 months)
  3. Consult on updated flood maps and seek community feedback (consultation period: 2 months)
  4. Review community submissions, validate and finalise flood maps (planning period: 3 - 6 months)
  5. Publish final flood maps ready for use in decision making (publishing period: 1 month) and request authorisation for Planning Scheme Amendment
  6. Publish updated flood emergency management plans (planning period: 2 months)

About the program

The Greater Melbourne Flood Information Program will update more than 60 maps across 38 council areas over the next few years.

Flood maps provide valuable information that helps the Victorian Government, councils, emergency services and communities to:

  • prepare for floods and minimise their impacts
  • ensure new housing is built to withstand floods, and away from high-risk locations
  • prioritise upgrades to flood infrastructure in high-risk areas.
