Early Whale Arrivals Off Victoria Coast, Australia
The whales don't usually appear off the Victorian coast until April or May, when they migrate from chilly Antarctic waters to breed in the balmy seas off Queensland.
But two early sightings - one of a young calf off the Gippsland coast last month and another of three whales near Marengo this week - have scientists scratching their heads.
"We don't know why these whales are appearing early," said Mandy Watson, a Department of Sustainability and Environment senior biodiversity officer.
"It could be a response to climatic conditions or a result of population recovery, or both."
