The Park was one of the first declared in New South Wales, NSW and stretches along the northern New South Wales, NSW coast, from Muttonbird Island Nature Reserve, Muttonbird Island, Coffs Harbour, to Plover Island near Sandon River, 75 kilometres to the north. It includes coastal estuary, estuaries and lakes and extends from the mean high water mark, to three nautical miles out to sea, covering an area of around 72 000 hectares.NSW Marine Parks Authority. (2013). ''Solitary Islands Marine Park - Southern Sanctuary Zone.'' There are five main islands in the Park, North Solitary Island, North West Solitary Island, South West Solitary Island (Groper Island), South Solitary Island and Split Solitary Island, as well as other significant outcrops such as Muttonbird Island and submerged reefs.
On 15 May 1770, Lieut. James Cook sailed past the Solitary Islands and noted their position in his journal, “Between 2 and 4 we had some small rocky Islands between us and the land the southernmost lies in the Latitude of 30°10' and the northernmost in 29°58' and about 2 Leagues or more from the land.”Cook, J.

At the edge of the marine park, the endangered Little Bent-wing Bat, (''Miniopterus australis'') roost in caves on the Moonee Beach headland. While there was a lighthouse keeper on South Solitary Island, rabbits (''Oryctolagus cuniculus''), goats (''Capra hircus'') and dogs were introduced to the island to the detriment of the vegetation, but these animals have since been removed. Rats (''Rattus norvegicus''), bandicoots (''Isoodon spp.'') and foxes (''Vulpes vulpes'') have been found on Muttonbird Island, which is connected to the mainland by a causeway, however National Parks and Wildlife Service have an eradication program in place to control this.
858 species of fish are found in the Solitary Islands Marine Park. The area around Pimpernel Rock, at the northern end of the Solitary Islands Marine Reserve (Commonwealth Waters) is favoured by the endangered Grey nurse shark (''Carcharias taurus''), who has a preference for gutters in reefs and submarine caves. However the most significant habitat for the grey nurse shark in the Marine Park is South Solitary Island, though they do occur throughout the park. The Great white shark (''Carcharodon carcharias'') is also seen around Pimpernel Rock. There are many species of reef fish in the Park, including snapper (''Pagrus auratus''), tusk fish (''Choerodon venustus''), blue morwong (''Nemadactylus douglasii'') and pearl perch (''Glaucosoma, Glaucosoma scapulare'') as well as pelagic species such as kingfish (''Seriola lalandi'') that are attractive to commercial and recreational fishermen. Commercial fishing fleets operate from Coffs Harbour and Wooli.
The area on the western side of North West Rock (off North Solitary Island) is known as "Fish Soup” and has a very high diversity of fish. Tropical predators like spangled emperor (''Lethrinus nebulosus''), bigeye trevally (''Caranx sexfasciatus''), mangrove jack (''Lutjanus argentimaculatus''), moses perch (''Lutjanus russellii'') and brown sweetlip (''Plectorhinchus gibbosus'') occur with mulloway (''Argyrosomus japonicus''), snapper, red morwong (''Cheilodactylus fuscus''), silver trevally (''Pseudocaranx georgianus''), bream (''Acanthopagrus'' spp.) and tarwhine (''Rhabdosargus sarba'').

Even though the Marine Park is a protected zone, commercial fishing and recreational activities such as fishing, crabbing, boating and scuba diving are allowed in some zones of the park. Environmental threats to the Solitary Islands Marine Park may include pollution, introduced predators, oil spills, humans, dredging, sewage outfalls, shipping, marine debris, and tourism. Introduced pests such as the Pacific Oyster (''Crassostrea gigas'') and the Crown-of-thorns starfish (''Acanthaster planci'') are occasionally recorded in the area.
Introduced domestic animals on South Solitary Island during the days of lighthouse keepers, destroyed the natural vegetation, and eroded topsoil,NSW National Parks and Wildlife Service. (2012). ''Solitary Islands group of reserves: Draft Management Plan''. NSW Office of Environment and Heritage. which in turn caused the nesting Wedgetail shearwaters’ burrows to collapse.
An accidental fire on South West Solitary Island, caused by fishermen, destroyed much vegetation, killing nesting birds and their eggs.
Due to the rocky nature of the area, a number of ships were wrecked on the northern NSW coast. This led to the construction of a series of lighthouses, with the South Solitary Island lighthouse being completed in 1870.
During the 1960s and 70s many of the beaches were affected by sand mining.
Litter in marine environments is a threat to seabirds, causing entanglement or ingestion of debris, often leading to death.
The Solitary Island Marine Park is managed by the New South Wales, NSW Maritime Parks Authority and is split into 4 management zones: Sanctuary zones (12%) which provide the highest level of environmental protection, with all fishing activities prohibited. Habitat protection zones (54%) allow for many recreational activities such as fishing but provides a high level of environmental protection. General use zone (34%) allows commercial fishing as well as a wider range of activities, and lastly the Special Purpose zones (0.1% of park) cover sites of cultural significance to the Aboriginal Australians, Aboriginal community, research sites and oyster leases.NSW Marine Parks Authority.

Retrieved 20/05/2015, from http://www.mpa.nsw.gov.au/simp-consulatation.html South Solitary Island with its lighthouse and cottages is a historic site. Visiting the island is allowed for two weekends of the year, in July, by helicopter.
Public Moorings: A number of public moorings have been installed in the Park, and are located within the sanctuary zone around Northwest Rock, North Solitary Island, North West Solitary Island, South West Solitary Island (Groper Is.), Split Solitary Island, South Solitary Island and Surgeons Reef.

Ecology
The Solitary Island Marine Park contains a diverse range of habitats including intertidal and subtidal reefs, soft sediments, beaches, seagrass beds, mangroves, saltmarsh and open waters, which support a large variety of fauna and flora. The northern section of the marine park borders the Yuragir National Park, between Sandon River and Red Rock, which contains several open and closed lakes and lagoons. As well as bordering Moonee Beach Nature Reserve, Garby Nature Reserve at Arrawarra, and Coffs Coast Regional Park, it also incorporates Muttonbird Island Nature Reserve, Split Solitary Island Nature Reserve, South West Solitary Island Nature Reserve, North West Solitary Island Nature Reserve, North Rock Nature Reserve, North Solitary Island Nature Reserve and the South Solitary Island Historic Site which covers 11 hectares and incorporates the lighthouse and keepers cottages built in 1879. Prior to European settlement, none of these islands had been inhabited, burned or subject to grazing animals. A fragile balanced ecology had built up over centuries.Yeates, N. T. M. (1990).

At the edge of the marine park, the endangered Little Bent-wing Bat, (''Miniopterus australis'') roost in caves on the Moonee Beach headland. While there was a lighthouse keeper on South Solitary Island, rabbits (''Oryctolagus cuniculus''), goats (''Capra hircus'') and dogs were introduced to the island to the detriment of the vegetation, but these animals have since been removed. Rats (''Rattus norvegicus''), bandicoots (''Isoodon spp.'') and foxes (''Vulpes vulpes'') have been found on Muttonbird Island, which is connected to the mainland by a causeway, however National Parks and Wildlife Service have an eradication program in place to control this.
Fish
858 species of fish are found in the Solitary Islands Marine Park. The area around Pimpernel Rock, at the northern end of the Solitary Islands Marine Reserve (Commonwealth Waters) is favoured by the endangered Grey nurse shark (''Carcharias taurus''), who has a preference for gutters in reefs and submarine caves. However the most significant habitat for the grey nurse shark in the Marine Park is South Solitary Island, though they do occur throughout the park. The Great white shark (''Carcharodon carcharias'') is also seen around Pimpernel Rock. There are many species of reef fish in the Park, including snapper (''Pagrus auratus''), tusk fish (''Choerodon venustus''), blue morwong (''Nemadactylus douglasii'') and pearl perch (''Glaucosoma, Glaucosoma scapulare'') as well as pelagic species such as kingfish (''Seriola lalandi'') that are attractive to commercial and recreational fishermen. Commercial fishing fleets operate from Coffs Harbour and Wooli.
The area on the western side of North West Rock (off North Solitary Island) is known as "Fish Soup” and has a very high diversity of fish. Tropical predators like spangled emperor (''Lethrinus nebulosus''), bigeye trevally (''Caranx sexfasciatus''), mangrove jack (''Lutjanus argentimaculatus''), moses perch (''Lutjanus russellii'') and brown sweetlip (''Plectorhinchus gibbosus'') occur with mulloway (''Argyrosomus japonicus''), snapper, red morwong (''Cheilodactylus fuscus''), silver trevally (''Pseudocaranx georgianus''), bream (''Acanthopagrus'' spp.) and tarwhine (''Rhabdosargus sarba'').
Reptiles
Marine turtles are common in the Park, with green turtle (''Chelonia mydas''), loggerhead turtle (''Caretta caretta''), hawksbill turtle (''Eretmochelys imbricata'') and occasional sightings of leatherback turtles. Nesting green turtles and loggerhead turtles have been recorded on several beaches, with some eggs hatching successfully. Only a few species of sea snakes have been recorded in the region, including the Elegant sea snake (''Hydrophis elegans'') and Yellow-bellied sea snake (''Pelamis platurus''). The only reptile recorded on Muttonbird Island since 1969 is Burton’s Snake Lizard (''Lialis burtonis'') though Eastern Water Dragons (''Physignathus lesueurii'') were plentiful prior to 1930.Invertebrates
At depths greater than 25 metres the sea bottom is dominated by sponges and invertebrates. More than 700 species of molluscs (snails and shellfish) and coral are found in the Marine Park. Invertebrate species found include blue-bottles, sea-squirts, sea-whips and black coral (''Antipatharia''), as well as oysters (''Saccostrea'' and ''Crassostrea'' species) and crustaceans such as crabs (''Scylla serrata'', ''Portunus pelagicus'' and ''Ranina ranina''), prawns (all species in family Penaeidae) and crayfish (''Jasus verreauxi'', ''Scyllarus spp.'' and ''Panulirus spp.''). Commercial prawn trawling is allowed in the general use area of the Park and crab and lobster trapping in both the general use and habitat protected areas.NSW Marine Parks Authority. (2011b). Solitary Island Marine Park & Solitary Islands Marine Reserve (Commonwealth Waters) - zoning summary and user guide.Coral
The Solitary Islands region contains the southernmost extensive coral communities in coastal eastern Australia. The East Australian Current transports the coral larvae from the warm tropical waters, and with 90 reported species, there are approximately quarter of the species recorded on the Great Barrier Reef.Harriott, V. J., Smith, S. D. A., & Harrison, P. L. (1994). Patterns of coral community structure of subtropical reefs in the Solitary Islands Marine Reserve, ''Eastern Australia.

Environmental threats and issues
Even though the Marine Park is a protected zone, commercial fishing and recreational activities such as fishing, crabbing, boating and scuba diving are allowed in some zones of the park. Environmental threats to the Solitary Islands Marine Park may include pollution, introduced predators, oil spills, humans, dredging, sewage outfalls, shipping, marine debris, and tourism. Introduced pests such as the Pacific Oyster (''Crassostrea gigas'') and the Crown-of-thorns starfish (''Acanthaster planci'') are occasionally recorded in the area.
Introduced domestic animals on South Solitary Island during the days of lighthouse keepers, destroyed the natural vegetation, and eroded topsoil,NSW National Parks and Wildlife Service. (2012). ''Solitary Islands group of reserves: Draft Management Plan''. NSW Office of Environment and Heritage. which in turn caused the nesting Wedgetail shearwaters’ burrows to collapse.
An accidental fire on South West Solitary Island, caused by fishermen, destroyed much vegetation, killing nesting birds and their eggs.
Due to the rocky nature of the area, a number of ships were wrecked on the northern NSW coast. This led to the construction of a series of lighthouses, with the South Solitary Island lighthouse being completed in 1870.
During the 1960s and 70s many of the beaches were affected by sand mining.
Litter in marine environments is a threat to seabirds, causing entanglement or ingestion of debris, often leading to death.
Management
The Solitary Island Marine Park is managed by the New South Wales, NSW Maritime Parks Authority and is split into 4 management zones: Sanctuary zones (12%) which provide the highest level of environmental protection, with all fishing activities prohibited. Habitat protection zones (54%) allow for many recreational activities such as fishing but provides a high level of environmental protection. General use zone (34%) allows commercial fishing as well as a wider range of activities, and lastly the Special Purpose zones (0.1% of park) cover sites of cultural significance to the Aboriginal Australians, Aboriginal community, research sites and oyster leases.NSW Marine Parks Authority. (nd). Solitary Islands Marine Park: Consultation & Management. Retrieved 20/05/2015, from http://www.mpa.nsw.gov.au/simp-consulatation.html South Solitary Island with its lighthouse and cottages is a historic site. Visiting the island is allowed for two weekends of the year, in July, by helicopter.
Public Moorings: A number of public moorings have been installed in the Park, and are located within the sanctuary zone around Northwest Rock, North Solitary Island, North West Solitary Island, South West Solitary Island (Groper Is.), Split Solitary Island, South Solitary Island and Surgeons Reef.
