Limmen Bight Marine Park

Park declaration

Following public consultation, in 2012, the Territory Government declared Limmen Bight Marine Park.

Limmen Bight Marine Park is approximately 880 km2 in size and is located in the Gulf of Carpentaria, 340 km southeast of Katherine and 100km northwest of Borroloola.

Marine parks are parts of the ocean that are managed specifically to conserve key habitats and the plants and animals that live within them. Protecting areas that contain different wildlife and habitats helps to maintain the long term health and productivity of our waters, particularly for species other than fish.

Marine parks are often multiple-use, meaning different activities are allowed in different parts of the park. Marine Parks work in unison with other NT legislation, such as the Fisheries Act, to ensure ongoing sustainable development of the Territory.

The marine and coastal areas of Limmen Bight are highly productive and the Limmen Bight Marine Park will help protect

a rich marine environment and biodiversity, including:

  • Extensive seagrass beds, which are important foraging areas for dugong and marine turtles, and for seahorses and pipefish;
  • Part of the largest (and internationally significant) dugong populations in the Territory; and
  • Nesting of threatened Flatback Turtles on Maria Island, and turtle feeding grounds in adjacent waters.

Parks that connect across the land and sea are of special significance. The Marine Park will link with Limmen National Park; ; forming a strong connection across land and sea in this region.


Limmen Bight Marine Park comprises 880  km2 of shallow sea in the Gulf of Carpentaria with a rich array of  saltwater wildlife species. The Marine Park includes part of the largest  density of Dugongs in the Northern Territory and is also home to some rare,  listed Pipefish species.  The Park has a rich and active Aboriginal  culture. The Marra, Yanyuwa, Alawa and Wandarang peoples have strong cultural affiliation with this saltwater country.

How  to Get There?

Limmen Bight  Marine Park is located 340 km south-east of Katherine along the Carpentaria  Highway and 100 km north-east of Borroloola. The Marine Park can be accessed  via boat ramps at Borroloola and fishing camps on the Roper and Limmen Bight  Rivers. It can also be accessed by sea from the Gulf of Carpentaria.  

When  to Visit

The Park is open  all year. The dry season (May-Sept) is the most pleasant months to visit.  Please remember that tropical cyclones and storms can affect this area during  the wet season.

What  to See and Do?

The Marine  Park is a multi-use "fishing-friendly" park so therefore one of the main  activities on the Park is recreational fishing. However wildlife spotting is an  ever-growing activity across the Northern Territory with many visitors coming  to the Territory to see specific species in the wild. The range of wildlife  species that can be observed and photographed include marine seas Turtles, Saltwater Crocodiles, Dugongs, Dolphins, Freshwater Sawfish and many others. The surrounding islands and mainland are also important areas for a multitude  of waterbirds, shorebirds and seabirds.
Please remember: Swimming is not advised as  Estuarine (Saltwater) Crocodiles live and travel throughout the Marine Park.

Fact Sheets

Recreational  Activities

The largest recreational activity in this area is fishing. Important fish stocks  make this marine park a paradise for the fishing enthusiast who enjoys remote  areas. The area also includes important commercial quantities of Prawn, Mud Crab and Barramundi. These populations are important for both the  commercial and recreational fishers of the region.

Plants and Animals

The Marine Park has a multitude of important wildlife. Most of the area has not been  extensively surveyed so it is expected that even more important marine species  will be discovered in the area into the future.

At least three species of Pipefish (Hippichthys cyanospilos, H. parvicarinatus and H. penicillus) live in the seagrass meadows  of the Park. Pipefish are closely related to Seahorses and these species are  listed marine species under the Commonwealth Environment Protection and  Biodiversity Conservation Act.

The Park also protects part of the largest density  of Dugongs in the Northern Territory. The important and extensive seagrass meadows provide important feeding grounds for this species. The meadows are  also critical for the local marine turtle populations that include Flatbacks, Greens, Hawksbills and Olive Ridleys. Marine turtle populations are in decline across  the planet and this area protects one of their important feeding areas, adjacent to important nesting areas.

The Park provides feeding resources for the adjacent waterbird, shorebird and seabird populations. These colonies include species such as the great, intermediate and  little egrets, Australian Pelicans, Pied Cormorants, Black-winged Stilts, Red-necked Avocets, Silver Gulls and many other notable species.

  Suitable habitat exists for inshore dolphins such as Australian snubfin and Indo-Pacific humpback, and the region is expected to be  important for both species.
