Australian wildlife officials began disposing of hundreds of dead pilot whales on Saturday after concluding there was no longer any hope of rescuing any more.
In Australia's biggest whale beaching, 470 whales were first spotted on a wide sandbank during an aerial reconnaissance of rugged Macquarie Harbour in Tasmania state on Monday.
After days of difficult and dangerous rescue attempts, Australia said they rescued 108 whales, with the rest now believed to have died.
Rob Buck, Incident Controller and Parks and Wildlife Service manager, said 15 whales have already been disposed of at sea, but the operations to dispose the remaining near 350 mammals was expected to take several days at least.
"Collection and disposal is being undertaken with the assistance of aquaculture companies whose equipment and expertise on the harbour is essential for a timely and effective outcome," Buck said in an emailed statement.
The bodies of the dead whales were being separated into groups and enclosed with water booms to try keep them in one place and isolated from sharks and other predators.
