Healthy coastal habitats

Delivering healthy coastal habitats with sustainable use and development

Taking action to improve the management of foreshore and waterway structures to protect the marine environment.


Commercial dredging audit

Reviewing commercial dredging and sand extraction in estuaries and along the open coast to assess risks and ensure a consistent approach to risk management.

Fish friendly breakwalls

Developing guidelines and plans to include features in new and existing estuary breakwaters that will improve biodiversity, fishing and other social values.

Project completed.

ICOLL management

Developing an approval framework to support entrance management for intermittently closed and open lakes and lagoons (ICOLL).

Coastal design guidelines review

Improving the design of coastal cities and towns by promoting environmentally friendly planning and infrastructure.

Domestic waterfront structure strategies

Developing estuary-wide strategies for jetties, pontoons and boat ramps to streamline approvals while protecting aquatic habitat.

Marine vegetation strategies

Developing estuary-wide strategies for rehabilitating and protecting mangroves and saltmarsh so they are resilient to key threats.

Estuary foreshore management strategies

Developing environmentally friendly methods of bank stabilisation to manage foreshores and guide future investment.

Coastal floodplain drainage management

Providing a framework for managing coastal floodplain drainage to improve water quality, simplify approvals and support viable primary industries.

Reconnecting fish habitats

Restoring fish passage and river connectivity at priority weir and road crossings so that fish can move between habitats, avoid predators, find food and breed.

Mapping seagrass, mangrove and saltmarsh

Developing new methods for mapping seagrass, mangrove and saltmarsh to determine species, measure condition and identify threats.

Innovative technology research

Exploring ways of using artificial intelligence to map and monitor habitats and species.

Threats to estuarine vegetation

Understanding the effects of human activities on seagrass, mangrove and saltmarsh.

Subtidal reef monitoring

Improving knowledge about deep rocky reef species in the Greater Sydney region and the effects of natural and human influences.

Reviewing jetty designs

Improving the design of jetties to minimise seagrass loss in Greater Sydney estuaries.

Threats to estuarine fish assemblages

Understanding the effects of human activities on fish in Greater Sydney estuaries.
