That's a migaloo, or a white humpback whale (which may or may not be an albino, scientists aren't sure):
Record numbers of humpback whales are on their annual migration up Australia's east coast, including the rare white whale Migaloo, scientists say.
Migaloo, whose Aboriginal name means "white fella", is believed to be the only completely white humpback whale in the world.
