Marine rescuers will scale down their mission to free whales involved in a mass stranding on Tasmania's west coast, as the priority shifts to at-sea burials for about 200 dead animals.
There were no surviving pilot whales left on Ocean Beach near Macquarie Harbour, south of Strahan, as of Saturday, incident controller Brendon Clark confirmed.
However, authorities spotted a small number of whales within the harbour precinct.
