Located between Broome and Port Hedland, Eighty Mile Beach is the longest beach in Western Australia spanning 220km from Cape Missiessy to Cape Keraudren.

Eighty Mile Beach is a significant flatback turtle (Natator depressus) rookery and its adjacent waters important foraging grounds.

Under the Ramsar Convention of Wetlands, Eighty Mile Beach has also been classed a Wetland of International Importance due to the significance of the feeding grounds for migratory shorebirds and waders. In many parts, the expansive mudflats extend up to 4km.

In 2013, Eighty Mile Beach was gazetted as a Marine Park to be jointly managed by Department of Parks and Wildlife and Traditional Owners of Eighty Mile Beach. A Marine Park is a multiple use area which aims to conserve the cultural, ecological, recreational and commercial values within the Park. Eighty Mile Beach Marine Park’s diverse marine environments include intertidal, mudflat, macroalgal, seagrass, coral reef and mangrove communities which support a rich array of marine life including dugongs, cetaceans, seabirds, finfish, sharks, rays and a diverse range of invertebrates.

Although flatback turtles were known to nest along Eighty Mile Beach, no official records exist before 2005 when Conservation Volunteers Australia (CVA) and Care for Hedland (CFH) conducted preliminary turtle monitoring at Anna Plains (northern end of Eighty Mile Beach). Between 2006 and 2012 the Department of Parks and Wildlife (then known as the Department of Environment and Conservation or DEC) in collaboration with CVA conducted annual turtle monitoring at the Eighty Mile Beach Caravan Park site (6km), and in some years monitoring was also performed at Anna Plains (at various locations).

Since the creation of the Marine Park in 2013, Parks and Wildlife have taken responsibility of the Eighty Mile Beach Turtle Monitoring Program. Each season Parks and Wildlife together with the Traditional Owners monitor two sites, each six kilometres in length:-

• Eighty Mile Beach Caravan Park– Nyangumarta Country

• Yawinya (Anna Plains)– Shared Country (Nyangumarta and Karajarri)

The components of the Turtle Monitoring Program at Eighty Mile Beach include:-

• Track monitoring

• Remote Camera surveillance

• Nest exhumations

• Satellite tracking

• Other research (climate change and effects on egg incubation, genetic sampling etc)

Since 2012, BHP Billiton have provided financial support to the Eighty Mile Beach Turtle Monitoring Program through the Eighty Mile Beach and Walyarta Conservation Program, an investment made under the BHP Billiton Community Development Program. The additional funding ensures long term conservation objectives of this Program is achieved through the expansion of the Eighty Mile Beach Turtle Monitoring Program to include:-

• Satellite tracking – monitor inter-nesting movements, post-nesting migration and identify foraging grounds

• Remote camera surveillance – monitor nests for predation and nest disturbance

• Aerial surveys – determine the distribution and abundance of turtle activity along the length of Eighty Mile Beach

• Traditional Owner Engagement – reintroduce second monitoring site at Anna Plains, provide opportunities for training and employment in all areas of the Program
