Sometimes a piece of vision pretty much says it all - as is the case with this amazing footage of a humpback all but leaping into a whale-watching boat off the coast of Port Macquarie.

The 18-person tour group had been following a pod of whales for about 20 minutes and thought the playful group swimming around and under the boat was as entertaining as it might get.

But five minutes later they were blown away as an adolescent whale rocketed out of the water, performing an acrobatic roll and then plunging back into the ocean - spraying a plume of water over the boat.

Anne Collins was among the excited passengers who was totally thrilled by what she witnessed.

“Then this thing just went whack and up above boat, and crashed back down...It's so exciting....awesome,” she told 7 News.

“It was fan-bloody-tastic."
