It is one of the world's most important seabird breeding sites, and is the centre of Western Australia's largest single-species fishery, the western rock lobster fishery. It has a small seasonal population of fishermen, and a limited number of tourists are permitted for day trips, but most of the land area is off-limits as conservation habitat. It is well known as the site of numerous shipwrecks, the most famous being two Dutch ships: Batavia, which was wrecked in 1629, and Zeewijk, wrecked in 1727.
The islands are an unincorporated area with no municipal government, subject to direct administration of the Government of Western Australia. In July 2019, the Houtman Abrolhos was declared a national park by the state government.
