Every year up and down the east coast of Australia between April and November each year thousands of Humpback whales travel to mate and breed. During summer the Humpback whales go to the antarctic to feed on krill and migrate north to sub-tropical waters where they mate and then give birth to their calves. Along their journey tourists and whale watchers are treated to an awesome acrobatic display in the Pacific ocean waters. Their epic journey covers around 10,000 kilometres.
