A discovery of ancient artefacts on the seabed off Australia's west coast has opened up a new frontier for resource companies to watch out for in conserving indigenous heritage.
Archaeologists in July reported they had found hundreds of stone tools submerged off the Dampier Archipelago in Western Australia, showing evidence of people living in the area when it was dry land more than 7,000 years ago.
The two sites are about 5 kilometers (3 miles) east of where Woodside Petroleum, Australia's top independent gas producer, plans to build a pipeline connecting its Scarborough gas field to its Pluto gas plant on the Burrup Peninsula.
