In the lower reaches of Saltwater Creek off Bramble Bay, Hays Inlet is a wetland and estuarine area lined with mangroves and coastal bushland. A unique environment, Hays Inlet is home to a range of habitats, including intertidal flats, mangrove forest, saltmarsh, Casuarina forest and open eucalypt forest.
Due to its high levels of productivity and the importance of the breeding grounds, sections of Hays Inlet have been protected against commercial fishing for about 50 years.
As part of the Moreton Bay Marine Park, the Hays Inlet Conservation Park supports and protects wildlife such as kangaroos, flying foxes, Eastern Curlews, fish, crabs and prawns.
