These surfers look miniscule in comparison to the majestic marine mammal in their midst.
The amazing scenes of a southern right whale emerging from turquoise waters were captured at Freshwater Beach off the coast of Sydney on Sunday.
But the awe-inspiring sight belies a hidden danger - last year a surfer was injured by the same species of whale at Bondi Beach.
And, aware of the risk of injury from the animal’s huge fins, the surfers in the video are seen quickly paddling away as the whale turns in the waves.
The footage was filmed from a helicopter by Australian TV channel Nine News.
The whale appeared to be in a playful mood, swishing its tail and swimming alongside the surfers - but the fun and games were restricted by national law, which dictates that swimmers should not be closer than 30 metres to a whale, while surfers and boats are required to keep 100 metres away.
Resident Ian Hansen, who witnessed the scenes, told Fairfax Media: “To be honest they were harassing it a bit. They were so close and it had no room to move... If I was the fish I'd be harassed too. It'd move a bit and they'd back off.
“I was pretty worried to see one guy out there with a kid on his board. It's a big animal, one tail flick and we could have a death on our hands,” he added.

2/23 Glass frog
Scientists in South America have discovered a brand new species of frog – and he’s a dead ringer for Kermit the frog. Hyalinobatrachium dianae is an inch-long glass frog with identical bright green skin, a translucent belly, and bulging white eyes with black pupils. The new species found by Costa Rican Amphibian Research Center on the Talamanca hills of the country, was named after the senior researcher’s mother Diane and brought the total known species of glass frogs on the island to 14

3/23 Walking fish (climbing perch)
A bizarre and seemingly super-powered fish which can walk out of water and breathe on land for up to six days could spell a 'major disaster' for wildlife, scientists have warned. The aggressive climbing perch, which has lungs as well as gills, has been discovered in northern Australia
4/23 Frilled shark
A rare and terrifying frilled shark has been pulled from the water by fishermen near Lakes Entrance in Victoria, Australia. Also known as the "living fossil", the frilled shark is named for its six pairs of frill-like gills. The shark’s origin dates back 80 million years, and is one of two species that is still alive from this period
5/23 Black Sea Devil anglerfish
Researchers in the US have released what they believe to be the first video footage showing a bizarre-looking Black Sea Devil anglerfish in the wild. As anglerfish live in the deep sea, they are very rarely seen in their natural habitat, and fewer than half a dozen have ever been captured on film or video in the wild, according to experts at the Monterrey Bay Acquarium Research Institute (MBARI)
