This has been a bumper year for whale-watching on Australia's east coast, with thousands of humpbacks spotted cruising along their annual migration route.

This population was almost wiped out by whalers last century but has bounced back — and then some. A new estimate suggests there are now more of these humpbacks than in pre-whaling times.

So why are the eastern Australian humpbacks going gangbusters while other populations aren't doing nearly as well?
