Croc attack victim was a Kiwi - police

The victim's friend survived but has been left in deep shock after trying in vain to pull her from the croc's jaws.

A woman believed to have been killed in a crocodile attack in Australia is from New Zealand, it has been reported.

A Queensland Police Service spokesman said the woman taken by the crocodile was believed to be from New Zealand originally.

It was also believed she still had family living in New Zealand.

She had been living in Australia for 18 years.

A land, sea and air search for the woman was continuing, the spokesman said.

The woman was swimming with friends at Thornton Beach at the Daintree, 120km north of Cairns, Queensland when she vanished about 10.30pm last night local time.

Australian TV reports claimed the 46-year-old was heard to scream "a croc's got me", before she was pulled under the water.

Police said the woman and a friend, 47, were in waist-deep water when the croc struck.

"Her...friend tried to grab her and drag her to safety but she just wasn't able to do that," Senior Constable Russell Parker told ABC radio.

The two women were not locals and might not have been aware that the area was well known as a crocodile habitat, Parker said.

The friend was taken to the Mossman hospital, suffering shock and a graze.

Queensland Ambulance Service spokesman Neil Noble told ABC: "The report that we have from the surviving woman is that they felt a nudge and her partner started to scream and then was dragged into the water."

Warren Enstch, who represents the area in the Australian Parliament, said the beach was beside a creek where tourism operators run crocodile-spotting tours.

Enstch said the two tourists had to have seen plentiful crocodile warning signs in the region.

"If you go in swimming at 10 o'clock at night, you're going to get consumed," he said.

The search has resumed for the woman, with SES, land and water police scouring the bushland near Thornton Beach.

The case has echoes of a fatal croc attack near the Daintree River just before Christmas in 1985.

Beryl Wruck, 43, was taken by a 5m croc after a fateful decision to take a late-night dip in the shallows of Barratt Creek after an evening of dancing and drinking with friends.

More recently, 5-year-old Jeremy Doble died when he was attacked by a 4.3m crocodile in a swamp behind his Daintree River home.

He vanished in February 2009, with his seven-year-old brother telling police he saw a croc in the water moments after the boy disappeared.
