Around 270 whales stranded off the coast of the Australian island of Tasmania, about 150 miles south of the mainland.

According to the details, the thick large black mammals reportedly maneuvering for space after getting stuck on Tasmanian sands on Monday morning. Up to 90 whales have been found dead.

The rescue operation is underway and marine specialists were trialing efforts to determine the best rescue methods to save others.

Rescuers in Australia say conditions are in their favor as they try to save stranded whales. Twenty-five has been returned to deeper waters, rescuers say.

Around 40 government scientists, 20 police officers, and local fish farmers and volunteers are involved in the rescue attempt.

While mass whale strandings occur relatively often in Tasmania, such a large group has not been seen in the area for more than a decade.

The last mass stranding off the coast of Tasmania was reported in 2009 when 200 whales beached themselves.

In 2018, more than 100 pilot whales died after beaching off the coast of New Zealand.
