Limeburners Creek

Limeburners Creek National Park is a coastal and estuarine protected area on the mid-north coast of New South Wales, located near Port Macquarie and encompassing the significant tidal wetlands and coastal heath systems of the Manning and Hastings river estuaries. Covering approximately 22,600 hectares across several sections, the park protects one of the largest coastal wetland systems in the region, including saltmarsh, mangrove, paperbark swamp, and coastal heath communities. The park is internationally significant for migratory shorebirds and provides critical habitat for a range of threatened coastal species.

The wetlands of Limeburners Creek National Park are of international importance for migratory shorebirds. Bar-tailed godwits, red-necked stints, and numerous other shorebird species from the East Asian-Australasian Flyway use the tidal mudflats and saltmarsh as refuelling and wintering habitat. The park's wetlands also support large populations of resident waterbirds including royal spoonbills, egrets, cormorants, and various duck species. The threatened beach stone-curlew nests in the park. Koalas inhabit the coastal forest. Sea turtles nest on adjacent beaches in summer.

Limeburners Creek National Park contains outstanding examples of coastal and estuarine vegetation communities. Grey mangroves and river mangroves dominate the tidal channels and lower estuarine margins. Saltmarsh vegetation with samphire, sea couch, and various salt-tolerant rushes occupies the upper tidal zone. Coastal paperbark swamp with swamp paperbark and swamp mahogany occupies the seasonally inundated flats. Coastal heath on the sandy substrates features wallum banksias and associated heath species. The diverse vegetation captures the full gradient from tidal to upland coastal communities.

The park occupies a coastal plain landscape of Holocene estuarine and coastal deposits. The tidal waterways are drowned river valleys formed by post-glacial sea level rise. The extensive tidal mudflats represent the accumulated sediment from thousands of years of mangrove and saltmarsh trapping. The sandy coastal substrates of the heath areas are derived from beach and dune deposits. The flatness of the coastal plain reflects the accumulation of Quaternary sediments across the ancestral river floodplains.

The park has a subtropical coastal climate with warm, humid summers and mild winters. Annual rainfall is approximately 1,400 millimetres, concentrated in summer. The wetlands support year-round waterbird populations, with shorebird numbers peaking during the northern hemisphere winter (September to March) when migrants arrive from breeding grounds in the Arctic. Summer sea turtle nesting activity coincides with the warmest sea temperatures.

The Biripi people are the traditional custodians of the Port Macquarie and Hastings River region, with the coastal wetlands providing exceptional fish and shellfish resources. The productive estuarine environment supported large Aboriginal populations. European settlement of the Port Macquarie region began with the establishment of a penal settlement in 1821, and the surrounding coastal country was developed for agriculture. The wetlands were recognised as significant wildlife habitat from the mid-20th century.

Limeburners Creek National Park was established to protect the significant wetland and coastal habitats of the Port Macquarie coast. The park protects some of the most significant shorebird habitat on the mid-north coast. Management focuses on protecting the wetland ecology, controlling invasive weeds particularly bitou bush in the coastal areas, and monitoring the shorebird populations that give the park its international significance.

Birdwatching is the primary attraction, with the tidal mudflats and saltmarsh providing outstanding shorebird viewing, particularly from September to March. Kayaking and canoeing in the tidal channels and mangroves provide an immersive wetland experience. Walking tracks through coastal heath explore the diverse heath flora. The beaches adjacent to the park provide swimming and fishing.

The park is accessed from Port Macquarie via several local roads. Day use areas provide basic facilities. Port Macquarie provides comprehensive visitor services approximately 15 to 30 kilometres from park access points. A national parks pass applies. The park is approximately 400 kilometres north of Sydney via the Pacific Highway.

Protecting the wetland ecology from invasive species and water quality impacts is the primary conservation focus. Bitou bush control on coastal dune and heath areas is ongoing. Water quality monitoring addresses concerns about upstream agricultural and urban runoff. Shorebird nesting and feeding habitat is managed to minimise disturbance. The park participates in international shorebird monitoring programs through the East Asian-Australasian Flyway Partnership.
