A young Swiss couple who were mauled by a shark during an early morning swim may have filmed the very attack that killed one of them and injured the other.

The tragedy occurred in the unpatrolled waters off Kylies Beach at Crowdy Bay, south of Port Macquarie, on Thursday.

Emergency services were called to the beach, known to be a shark hotspot, at about 6.30am following reports that a man and a woman had been attacked.

Despite the heroic efforts of bystanders, the woman, believed to be 25, succumbed to her injuries before paramedics arrived.

Her boyfriend, 26, who is believed to have been attacked while trying to save her, was airlifted to John Hunter Hospital in Newcastle and is in a serious but stable condition.

It has since been revealed that the Swiss tourists were filming dolphins in the water when the attack occurred.

Police are now reviewing their GoPro footage, which is understood to have captured dolphins in the moments before the attack.

Ambulance Superintendent Joshua Smyth praised a bystander who applied a makeshift tourniquet to the man’s leg, saying they ‘potentially saved his life’.

The couple is believed to have been attacked by a three-metre bull shark.

A police spokesperson confirmed that drum lines may be deployed in a bid to catch the shark responsible.

Surrounding beaches were closed while Surf Life Saving NSW deployed drones to locate the shark and monitor for ongoing risks.

It is understood the couple were staying at the Kylies Beach campground in Crowdy Bay National Park and had arrived only the night before the attack.

NSW operates a shark-monitoring program that sends alerts when tagged sharks come within 500 metres of receivers near 37 beaches along the coastline.

Kylies Beach does not have a receiver, with the nearest located about 30km south at Old Bar.

NSW Surf Rescue’s James Turner said the incident served as a reminder of the risks people face when swimming at non-patrolled beaches.

‘This is in a nice, secluded area where people go to swim, we want them to be aware of the risk in non-patrolled locations,’ he said.
