Coastal wetland rehabilitation


Coastal floodplain wetlands are a significant estuarine habitat type, particularly on the northern NSW coast.

Many of these coastal floodplain wetlands have been artificially drained through the installation of complex floodplain drainage infrastructure for many decades. This has led to degradation of this important habitat and environmental asset. Drainage has also increased the risk of impacts to the downstream estuary after floods, including the 2022 floods, via de-oxygenated (blackwater) and acidic water pollution events.

This Action will work with project partners to increase the environmental resilience of estuaries to floods through coastal floodplain wetland rehabilitation at several locations.


Projects underway

Tuckean Swamp

Hydrological modelling is being updated at Tuckean Swamp to understand future sea level rise risks and assess possible tidal restoration scenarios. Information will be used to determine a preferred restoration option and inform planning for any restoration activities.

Everlasting Swamp

Contributing to the Everlasting Swamp Rehabilitation Project, a multi-agency project led by DCCEEW and NPWS. Developing a wetland restoration solution at the Everlasting Swamp National Park and State Conservation Area.

Clybucca Wetlands

Assessing historical water quality data from Clybucca Creek and reviewing the effects of a temporary reintroduction of tide to the drainage network post flood. This analysis will assist planning for potential future changed management of the lower Clybucca floodplain wetlands.

Panboola

Options to increase the connectivity between the Pambula estuary and sections of coastal floodplain at Panboola within the Old Pambula Racecourse are being investigated. This will increase the health of the existing wetland area increasing its resilience, and that of the wider estuary, to future flood impacts.
