Mass Stranding and Euthanasia of False Killer Whales in Tasmania

More than 150 false killer whales have perished or are set to be euthanised following a significant stranding event on a remote beach in Tasmania.

More than 150 false killer whales have been caught in a tragedy after a mass stranding on the northern coast of Tasmania, leaving authorities with no option but to euthanise the majority. Reports indicate that around 90 of the 157 whales remained alive as of Wednesday, but expert assessments revealed that complex conditions made their rescue impossible.

The pod stranded near Arthur River, and the site is noted for its challenging access, causing difficulties in transporting rescue equipment. Witnesses, including local resident Jocelyn Flint, described the scene as heart-wrenching, highlighting the presence of juveniles and the distress displayed by the animals. "Their eyes are open, they're looking at me, like 'help'," Flint shared on the Australian Broadcasting Corporation.

After being stranded for 24 to 48 hours, the surviving whales were deemed to be under extreme stress. Marine biologist Kris Carlyon reported on the harsh terrain and impossible conditions for rescue operations, noting the site's difficult access. Attempts to relocate and refloat the animals failed as they struggled against the breaking surf.

Faced with continued poor conditions, the wildlife veterinarians opted for euthanasia, acknowledging the animals' increasing suffering. “Euthanasia is always a last resort,” stated Dr. Carlyon, emphasizing the grim nature of the decision.

The process was slated to start on Wednesday and extend into Thursday, with authorities also planning the disposal of the carcasses. The stranding site holds cultural significance for Indigenous Australians, prompting a suggestion from officials to leave nature to take its course.

Tasmania has a troubling history of mass strandings, accounting for more than 80% of Australia’s cases—many occurring along the island's rugged west coast. In 2020, a devastating stranding event resulted in the loss of around 470 pilot whales. The causes of such beaching events are still debated, though theories range from disorientation during hunting to strong social bonds within whale pods leading them astray.

As this poignant moment unfolds, authorities urge the public to stay clear of the area, especially amid ongoing bushfire threats and limited access routes.
