A shark that attacked two people on a remote New South Wales beach – killing a woman and wounding her partner – is unlikely to pose an ongoing threat, experts say.police are reviewing GoPro footage from the scene, which may shed more light on how the attack unfolded.

A Swiss couple were swimming at Kylies beach in the Crowdy Bay national park at dawn on Thursday when a 3-metre bull shark attacked the woman and then her partner when he tried to save her.

Emergency services were called at about 6.30am.

The woman, 25, died at the scene, while the man, 26, was airlifted to john Hunter hospital where he was in a stable condition, the hospital confirmed on Friday.

Surf Life Saving NSW said Kylies and nearby North Haven and Crowdy Bay beaches reopened at 12.30pm on Friday.the beaches were reopened “following increased jet ski and drone surveillance since the incident … which has not identified any concerning marine life in the vicinity”, a spokesperson said.

“Ahead of the weekend, and noting the forecast hot temperatures that will attract large crowds to the beaches, drones will continue to provide shark surveillance to the area, particularly at Camden Haven and crowdy Head, with nippers set to go ahead as scheduled on Sunday.”

NSW Ambulance insp Kirran Mowbray told the Nine Network on Friday that “the shark has attacked the female first, and her partner has done everything he could to get them both into shore and yell out for assistance to a bystander who was there”.

Mowbray said the bystander used her swimmers as a tourniquet, tying them around the man’s leg.

“She’s essentially saved his life and bought him time before [paramedics] can get there,” he said.

Shark Attack at Kylies Beach Confirmed as Bull Shark encounter

A large bull shark, estimated to be over three metres in length, was likely responsible for the fatal attack at Kylies Beach in western Australia on Saturday, according to the Department of Primary Industries and Regional Development (DPIRD).

The victim, a 39-year-old man, was surfing when he was attacked. Emergency services were alerted around 9am, but the man died at the scene.

The Department of Primary industries deployed five “smart” drumlines at Kylies beach after the attack. These drumlines send alerts when sharks or other marine animals take a baited hook.The shark is then tagged, relocated 1km offshore, and tracked.

The department stated it “extends sincere condolences to the family and friends and first responders at this tragic time.” It also reported that no sharks have been caught on the drumlines at Crowdy Bay or at Port Macquarie to the north, or Forster to the south as the incident, and that there had been no drone shark sightings.

“Based on forensic analysis, DPIRD shark scientists have determined that a large bull shark over three metres in length was likely to have been involved,” the department said on Friday.
