'Despite the best efforts of volunteers and staff at Cheynes Beach to move the 45 whales to deeper water, at approximately 5pm on Wednesday all of the whales re-stranded just metres further along the beach.Within an hour of beaching, veterinarians had assessed the whales and confirmed they were displaying signs of rapid deterioration. Two whales died of natural causes. Our incident management team then determined the most appropriate and humane course of action was to euthanise the 43 remaining whales to avoid prolonging their suffering. '
