Whale watchers off the NSW mid-north coast have been treated to the spectacular sight of a humpback whale breaching completely out of the water just metres from their boat.

The incredible show was captured on video at the weekend during a whale watching tour off Port Macquarie.

Watch the spectacular show

The boat had been following a pod when an adolescent whale leapt right out of the water before rolling and smacking the water with huge force.

The vision was posted to Facebook by Port Macquarie’s Jet Cruise Adventures with the comment: “Some amazing footage captured by Tash Morton on this afternoons whale watch! Wave Rider got a wash!”

The huge breach had whale watchers laughing in awe at what they’d just see, as well as rather wet, with the whale sending a huge splash of water over the rocking boat.
