About Houtman Abrolhos Islands Marine Park

 

Located approximately 60 kilometers off the coast of Geraldton, Western Australia, the Houtman Abrolhos Islands Marine Park encompasses three main island groups: Wallabi, Easter, and Pelsaert. This area features vibrant coral reefs, seagrass beds, and numerous rocky islands that create critical habitats for abundant marine life and migratory birds. The marine park protects one of the southernmost true coral reef systems in the Indian Ocean, with over 200 species of fish, diverse coral assemblages, and significant seabird colonies. Historically, the islands are notable for shipwrecks, including the famous Batavia wreck from 1629, offering cultural heritage alongside natural wonders. Recreational activities include scuba diving and snorkeling to explore the reefs and wreck sites, as well as birdwatching on the islands, especially during breeding seasons. Fishing is regulated to sustain fish stocks while allowing for recreational angling. The marine park’s remote location provides a sense of wilderness and pristine conditions, appealing to naturalists, anglers, and adventure seekers alike. Access is limited, requiring planning and often boat charters from Geraldton. The area is managed under strict conservation guidelines to balance ecological sustainability with recreational use.
