Flood Management Strategy for Port Phillip and Westernport 2021-2031

The Flood Management Strategy for Port Phillip and Westernport sets the 10-year direction for flood management in the region.

The strategy is guided by a collective vision, objectives and 10-year outcomes. Under each outcome, the strategy identifies key focus areas which will guide our actions. The strategy will be delivered by partners that have flood management responsibilities, including:

  • local and state government
  • water authorities
  • emergency services

Partners will take a collaborative approach and work together to plan for, avoid and reduce flood risks while supporting emergency preparation and response.

Flooding in Melbourne's Port Phillip and Westernport region
The Port Phillip and Westernport region covers 13,000 square kilometres, from the Yarra Ranges in the east to Ballan in the west, and from Kinglake in the north down to the Mornington Peninsula and Phillip and French Islands.

Why we need a strategy

As the region’s floodplain manager, our role is to coordinate delivery of the strategy as required by the Victorian Government’s Floodplain Management Strategy. We all need to work together with the community to reduce the impacts of flooding, which poses risks to people, property, infrastructure and the environment.

Flood impacts can include:

  • deaths
  • injuries
  • property damage
  • social disruption
  • loss or disruption of critical infrastructure and services.

Climate change, sea level rise and urban densification are increasing flood risk. Despite an overall decrease in rainfall, climate scientists are projecting:

  • more frequent and severe floods
  • more intense rainfall events
  • continued sea level rise.
