WILDLIFE officers and volunteers are hoping 15 whales and dolphins that made it back out to sea after a mass stranding on a Bass Strait island at the weekend will keep swimming.
Sixty pilot whales and 20 bottlenose dolphins were found on New Year Island off King Island on Saturday, and late yesterday afternoon rescuers were still trying to save one whale which had been freed but then rebeached.
The stranding followed another beaching of dolphins at Quarantine Bay on mainland King Island on Friday.
Forty-two whales and 25 dolphins died.
Department of Primary Industries, Parks, Water and Environment marine biologist Rachel Alderman said beaches on both islands would be monitored for the possible return of the animals.
King Island was the scene of one of the state's biggest mass stranding in March 2009.
Volunteers and rescuers fought to save 54 pilot whales and five bottlenose dolphins that washed up on Naracoopa Beach but another 116 whales and two dolphins died.
More than 1000 whales and dolphins have been stranded on Tasmanian beaches in the past 30 years and what drives them inshore is still unclear.
Dr Alderman said it was likely to be a combination of factors, such as tide and currents, confusing the animals' navigation systems.
