Spencer Gulf Marine Park protects the unique marine ecosystems of South Australia's Spencer Gulf, offering opportunities for wildlife viewing, fishing, and marine recreation in a biologically rich coastal environment.
Spencer Gulf Marine Park is a protected marine area located in the waters of Spencer Gulf, on the southern coast of South Australia. Established to conserve the diverse marine habitats and species within the gulf, the park encompasses various coastal environments including seagrass beds, rocky reefs, sandy beaches, and open water. These habitats support a wealth of marine life such as leafy seadragons, Australian sea lions, dolphins, and migratory shorebirds. The gulf acts as an important breeding ground and nursery for a range of fish and invertebrate species, making the park critical for ecological sustainability and commercial fisheries. The marine park’s boundaries span from the southern entrance near Port Lincoln up to the upper gulf areas, covering vast expanses of the marine environment. Visitor activities primarily include recreational fishing, boating, wildlife observation, and snorkeling, with clear waters offering excellent opportunities for underwater exploration. The park also aims to balance conservation with sustainable use, enforcing zoning that regulates fishing practices and protects sensitive habitats. Nearby coastal towns provide access points for visitors, while interpretive signage and community engagement programs support awareness of marine conservation issues. The park is part of South Australia’s effort to maintain the health of its coastal ecosystems amidst increasing environmental pressures such as overfishing, habitat disturbance, and climate change impacts. Visitors often appreciate the natural quiet and scenic coastal outlooks, alongside abundant opportunities to see unique marine species in their natural environment.

Pristine seagrass beds supporting diverse marine life
Opportunities for sustainable recreational fishing in designated zones
Seagrass meadows within the marine park provide critical nursery and shelter areas for the elusive leafy seadragon, a species unique to southern Australia.
Several rocky outcrops and beaches along the gulf’s coast serve as haul-out and breeding sites for the vulnerable Australian sea lion.
Extensive seagrass beds stabilize sediments and support a rich diversity of fish, invertebrates, and waterbirds throughout the marine park.
