On Anzac Day, up to 160 long-finned pilot whales were stranded on the Western Australian coast near Dunsborough, resulting in at least 26 fatalities.

A coordinated rescue effort by government officials, volunteers, and experts successfully returned the majority to deeper waters, although 31 died on the shore.

The Department of Biodiversity, Conservation and Attractions suggests that euthanasia is often the most humane option for stranded whales, based on past incidents.

Researchers are investigating the stranding incident, considering factors like navigational confusion, predator avoidance, or human-made undersea noise as possible causes.

Post-rescue operations include monitoring to prevent the whales from re-stranding, utilizing ships and a spotter plane.

Authorities advise the public to keep a distance from the whales and to follow expert guidance to avoid additional harm to the animals and ensure human safety.
