The archipelago is also made up of reefs, shoals, channels and straits and is the traditional home of five Aboriginal language groups. It was formed 7000 years ago when rising sea levels flooded what were once coastal plains. The underlying rocks are among the oldest on Earth, formed in the Archaean period more than 2400 million years ago.
Despite being a region through which considerable shipping and industrial activity occurs, the archipelago has considerable marine resources.[2]
History
Dampier Archipelago is the site of some of Australia's oldest domestic structures, estimated to be between 8000 and 9000 years old.[3]
The largest island (or peninsula) in the group was known as Murujuga by the Yaburara people.[4] The first British settlers renamed it Dampier Island and it was later officially renamed Burrup Peninsula.
