Two Esperance anglers made international headlines after they reeled in two massive sharks off WA's north over the New Year, reports Yahoo News.

Joshua Butterworth and Jethro Bonnichta spent 10 days fishing on a beach north of Carnarvon and reported catching and releasing 30 sharks, including two "mega sharks" that captured international attention, The West Australian reported.

Joshua Butterworth and Jethro Bonnichta of Esperance, Australia, posed for photos of a massive hammerhead shark and an equally huge tiger shark that were estimated to weigh between 770 and 880 pounds, according to the Daily Mail.

Photos of a four metre hammerhead and an even bigger tiger shark attracted worldwide attention when US based fishing company Rogue Offshore posted it on their Facebook page. The photos gained worldwide attention by going viral on Facebook.

Butterworth, who sent the photos to Rogue Offshore, said the creatures were returned safely to the ocean.

"We take a lot of care in making sure they go back and making sure they are going to swim off strongly," he said.

"We could have killed them and claimed records but we let them go because they were still healthy."

The passionate young angler said it took about 90 minutes to catch the hammerhead, which stripped 800 metres of line three times.

"You have to run back to the sand dunes to make sure the angle of the line is right, there is a lot more to it than people think," he said.

Yahoo News reports Bonnichta collapsing from exhaustion after he reeled in the hammerhead.

The boys did not let the abundance of big sharks deter them from sharing their habitat.

"We were fishing straight out of our camp and we were swimming where we went fishing everyday," he said.

"These sharks are fine, they are well fed. It's the ones near Esperance we worry about."
