An amazing video has emerged of a pod of five humpback whales approaching a boat off the coast of Manly, Sydney, NSW, Australia.

The footage, shot on Monday, captures the moment five whales believed to be adolescent males surface next to excited whale watchers.

"We spotted whales breaching in the distance and as we approached the whales were just as excited to see us as we were to see them!" the filmer wrote online.

According to him, Blake Horton, owner of Manly Ocean adventures, said: "I've been leading tours for four years and never had an experience like this one".
