Melbourne Water protects Ramsar wetlands, vital for wildlife, culture, clean water and flood resilience. We work with partners to secure their future.

Flood models identify which areas are most likely to flood, how quickly, and how deep the water may get.

Flood management in Melbourne is a shared responsibility between Melbourne Water, councils, emergency services and other key partners.

The Western Port Ramsar site spans nearly 60,000 hectares of wetlands, tidal flats, and seagrass meadows. It is internationally recognised for its biodiversity, rich birdlife, and its role in supporting healthy marine and coastal ecosystems. These wetlands filter water, support fisheries, reduce flood risk, and provide habitat for thousands of native species.
