Coastal wetlands are important for keeping waterways healthy. They also provide habitat for a variety of wildlife.

Wetlands act as natural water filters. They trap sediment and nutrients that can cause water pollution.

Healthy wetlands support coastal waterways that are good for swimming, boating and fishing.

The coastal wetlands rehabilitation action aims to improve water quality and habitat in NSW by:

  • purchasing private wetland properties next to existing protected areas and managing them to deliver water quality and habitat functions
  • helping land owners improve the health of wetlands on their property
  • returning natural water level variation in some wetlands.


  • 408 ha of coastal wetlands now protected and added to the NSW Reserved Estate
  • 11,520 ha of NSW coastal floodplain wetlands studied to identify remediation options and inform planning, comprising:
    • Hydrological and remediation option assessments completed for coastal wetlands at: East Kinchela 2,100 ha (Macleay), Crookhaven River 1,050 ha (Shoalhaven), Tomago 500 ha (Hunter), Duck Creek 192 ha (Richmond), Werri Lagoon 85 ha (Gerringong), Jones Island 85 ha, Martells Road 7.5 ha
    • Cost Benefit Analysis reports prepared for 2 major coastal wetland rehabilitation projects: Tuckean Wetland 6,000 ha and Clybucca 1,500 ha
  • On ground rehabilitation works at Tomago and Crookhaven River.
