Ashmore Reef Marine Park

White-tip reef shark
Global FinPrint
Network: North-west
Marine park area: 583 kilometres2
Depth range: less than 15 – 500 metres
Average depth: 42 metres

Ashmore Reef Marine Park is situated about 630 kilometres north of Broome, and just 110 kilometres south of the Indonesian Island of Roti. Ashmore Reef was first proclaimed a marine reserve in 1983 under the National Parks and Wildlife Conservation Atc 1975. The marine park surrounds the largest of three emergent oceanic reefs in the region, and is considered a biodiversity hotspot for benthic and pelagic organisms. Reef ecosystems within the marine park are covered with hard and soft corals, huge sea fans, a variety of sea sponges and many different encrusting organisms. Seagrass meadows provide foraging grounds for dugongs and turtles, and the fish community is one of the most diverse in Western Australia. Ashmore Reef Marine Park is also an important breeding and foraging site for many shore and migratory seabirds, and is listed as a Ramsar Wetland of International Importance.

These short articles highlight the findings from ongoing scientific research within the Ashmore Reef Marine Park, including exciting new discoveries and ideas for future projects.
North Ashmore Reef 2017

Corals of Ashmore Reef face heat waves and coral bleaching in 2016 and 2017.

Ashmore Reef corals faced heat waves in 2016 and 2017 and escaped with relatively little damage, despite unusually warm ocean temperatures in 2016 causing extensive coral bleaching and the death of corals on many reefs across the world.

Natural values

Our marine parks have a number of different values, including natural, cultural, heritage and socio-economic values. The natural values of our marine parks refer to the habitats, species and ecological communities within them, and the processes that support their connectivity, productivity and function. Below are the key datasets that help inform park managers about the natural values that exist within our network of Australian Marine Parks. For more information on other park values refer to the relevant park Management Plans on the Parks Australia website.

Latest maps

Since the initial planning of the Australian Marine Parks Network in 2012, new mapping data has emerged that allows us to see in finer detail the features that exist within our parks. These datasets help marine managers to understand more about what's under the surface, where there are overlaying management or protection regimes, and/or where pressures on the marine environment may be increasing.
