Dozens of false killer whales stranded on a remote beach in the Australian state of Tasmania will be euthanised after bad weather and the isolated location hampered efforts to push them back into the waters,

Marine experts have given up hope of rescuing 157 false killer whales that stranded on a remote Australian beach.

Department liaison officer Brendon Clark said the stranding was the first by false killer whales in Tasmania in since 1974. That was a pod of more than 160 whales that landed on a beach near Stanley on the northwest coast. Strandings in Tasmania are usually pilot whales.
