Protected areas of Australia

Protected areas of Australia include Commonwealth and off-shore protected areas managed by the Australian government, as well as protected areas within each of the six states of Australia and two self-governing territories, the Australian Capital Territory and the Northern Territory, which are managed by the eight state and territory governments.

Commonwealth and off-shore protected areas in the Australian Capital Territory, the Northern Territory, the Christmas Island Territory, the Cocos (Keeling) Islands Territory, the Norfolk Island Territory and the Australian Antarctic Territory are managed by Director of National Parks, an agency within the Department of Climate Change, Energy, the Environment and Water, with the exception of the Great Barrier Reef Marine Park, which is managed by the Great Barrier Reef Marine Park Authority, a separate body within the department.

As of May 2025 protected areas cover 173,493,468 km² (66,986,202 sq mi) of Australia's land area, or about 22.57% of the total land area. The Australian Capital Territory has the highest level of protection at nearly 56% of its territory, followed by Tasmania with 43% and Western Australia with 31%. The lowest level of protection is in Queensland and New South Wales with 9.36% and 10.44% respectively. Of all protected areas, two-thirds are considered strictly protected (IUCN categories I to IV), and the rest is mostly managed resources protected area (IUCN category VI). Around 38% of the protected area in Australia is publicly owned and managed by the Australian government or state and territory governments. The largest component of protected areas are the Indigenous Protected Areas, at over 49% and growing as of February 2022.
