Protected areas of Western Australia are a network of national parks, nature reserves, marine parks, conservation parks and other statutory reserves across the Australian state of Western Australia. They encompass iconic landscapes such as the Kimberley, Pilbara, Wheatbelt, South West Australia biodiversity hotspot and the Nullarbor Plain, and include internationally recognised sites like Shark Bay and the Ningaloo Coast. These protected areas are managed under a framework of state and commonwealth instruments involving agencies such as the Department of Biodiversity, Conservation and Attractions, statutory trusts, and Indigenous organisations including Noongar corporations and native title holders.

Overview

Western Australia's protected estate spans terrestrial, freshwater and marine jurisdictions including bioregional reserves in the Interim Biogeographic Regionalisation for Australia, World Heritage Sites like Purnululu National Park, and internationally listed sites under the Ramsar Convention such as Lake Walyungup and Roebuck Bay. Protection categories reflect conservation, recreation, cultural heritage and resource management objectives across landscapes from the Great Sandy Desert and Tanami Desert margins to the temperate South West Australia ecoregion and coastal reefs of the Ningaloo Reef.

Types of protected areas

The statutory suite includes national parks (e.g. Karijini National Park, Cape Le Grand National Park), nature reserves for scientific values, conservation parks, historic reserves like Fremantle Prison, and marine protected areas such as the Muiron Islands Marine Management Area and Rowley Shoals Marine Park. Indigenous-managed estates include Indigenous Protected Areas (IPAs) such as Dambimangari IPA and Burrup Peninsula cultural zones, while private conservation initiatives involve organisations like the Australian Wildlife Conservancy and the National Trust of Australia (WA). Some areas are also recognised under the Biosphere Reserve programme and occur in collaboration with local government authorities like the Shire of Broome.

Governance and legislation

Primary legislative instruments include the Conservation and Land Management Act 1984 and the Environmental Protection Act 1986 (Western Australia), with overlapping Commonwealth arrangements under the Environment Protection and Biodiversity Conservation Act 1999. Management responsibilities rest with the Department of Biodiversity, Conservation and Attractions, statutory bodies such as the Botanic Gardens and Parks Authority, and Traditional Owner corporations operating under Native title determinations and Indigenous Land Use Agreements negotiated with the National Native Title Tribunal. International obligations arise from conventions including the World Heritage Convention, the Convention on Biological Diversity, and the Ramsar Convention on Wetlands.

Major reserves and national parks

Prominent terrestrial reserves include Karijini National Park in the Pilbara, Purnululu National Park in the Kimberley, Stirling Range National Park in the Great Southern, and Cape Le Grand National Park on the Eyre Highway approaches. Marine and coastal protected areas include Ningaloo Marine Park, Shark Bay Marine Park and Houtman Abrolhos Islands closures. The state also manages extensive nature reserves in the Goldfields-Esperance region, protected islands such as Rottnest Island, and significant freshwater refugia like Lake McLarty. Many sites intersect with heritage listings such as the Australia World Heritage List entries and sites of cultural significance to groups including the Yamatji, Noongar, Bunuba, and Yindjibarndi peoples.

Biodiversity and conservation priorities

Western Australia's protected areas conserve high endemism in hotspots such as the South West Australia region, with priority taxa including rare Banksia species, Eucalyptus communities, and endemic marsupials like the Numbat and Western Swamp Tortoise. Marine priorities focus on preserving Humpback Whale migratory corridors, reef biodiversity at Ningaloo Reef, and habitats for seabirds such as the Wedge-tailed Shearwater on the Houtman Abrolhos. Conservation science partnerships involve institutions like the Western Australian Museum, CSIRO, and universities including the University of Western Australia and Curtin University coordinating recovery plans, biodiversity surveys, and threatened species listings under state and national registers.

Threats and management challenges

Key threats include invasive species such as foxes and feral cats, altered fire regimes influenced by changes in Traditional burning practices, habitat fragmentation from agricultural conversion in the Wheatbelt, mining pressures in the Pilbara and Kimberley, and climate change impacts on species distributions and coral bleaching at Ningaloo Reef. Management responses combine pest control programs, prescribed burning practices informed by Traditional Owners and agencies like the Bushfire Centre for Excellence, restoration ecology projects led by organisations such as the Australian Wildlife Conservancy, and statutory impact assessments under the Environmental Protection Authority (Western Australia). Transboundary coordination involves Commonwealth agencies like the Department of Agriculture, Water and the Environment for matters of listed species and migratory protections.
