The world’s largest humpback whale population is booming thanks to the Kimberley Region in Western Australia.

The success of Western Australia’s humpback whales appears to be a combination of good feeding grounds in Antarctica, coupled with a lack of natural predators in the Kimberley’s calving grounds.

It has been estimated the whale population is increasing at around 10 per cent per year, with anywhere from 35 to 45 000 currently on the west coast.
