When experienced wildlife photographer Sean Scott flew his drone over a school of bait fish off a remote Western Australian beach, he never expected the images would attract global attention.

The Gold Coast-based photographer was on a caravan holiday with his family earlier this month after completing a photography project for Tourism WA.

He had just arrived at Red Bluff, 140 kilometres north of Carnarvon, when he saw the enormous school of fish.

"As soon as I pulled in I could see this big black bait ball pretty close to shore and so I was just sort of looking at that … and could see a few dark shapes around it," he said.

They were bronze whaler sharks and their numbers became more apparent from the air.

"When the drone went up I could see there were hundreds of sharks out there and I knew it was a pretty rare and special event," he said.

The sharks were feasting on the schooling fish, while nearby a group of teenagers on their boogie boards were seemingly oblivious to what was lurking nearby.

"They knew the sharks were in the water, but they didn't know they were that close," Mr Scott said.

Fearing an attack, he considered crashing his drone into the water to alert the surfers, until the sharks turned and headed to deeper water.

"It [the shark] went over and had a look at them and you could tell it wasn't interested in them," he said.

Mr Scott posted a photograph of two sharks swimming through a wave on his Facebook account, which was seen by 1.2 million people.

"I put it up as a little bit of teaser for my video, which I knew would go pretty well, but the shark photo is really what kicked it off," the photographer said.

The footage was bought by an Australian news outlet and was soon republished on news websites around the world.

Shooting wildlife is not new to Mr Scott, who's been travelling the globe for more than 15 years capturing nature at its most spectacular.

He has amassed 244,000 followers on Instagram and runs a popular photography gallery at Burleigh Heads.

It isn't the first time his work has gone viral, but he said capturing the WA shark feeding frenzy was his most satisfying shoot.

"It was a special moment that I got to see … and the thing that I was really proud about was that it wasn't just a fluke," he said.

"I wanted to be there at that time, because I knew the waves were good, the wind was right."

Mr Scott is now back on the Gold Coast and his next job is to photograph a surfing contest in the Maldives.

He said being a photographer is highly rewarding, if you're patient.
