The family of New Zealand-born crocodile attack victim Cindy Waldron doesn't want the animal harmed, saying it was in its natural habitat when she was taken in Queensland's Daintree National Park.
Ms Waldron, 46, has not been seen since she was dragged under the water at Thornton Beach, north of Cairns, after venturing into the water with friend Leeann Mitchell late on Sunday night.
As authorities continue what has now become a recovery operation, Ms Waldron's New Zealand-based father and sister arrived in Cairns to be closer to where she spent her final days and say goodbye.
"They were best friends and they hadn't seen each other for a while," Ms Waldron's sister Anna-Lee Annett said on Wednesday.
"They did something silly."
Ms Mitchell, who made frantic attempts to rescue Ms Waldron, has since left hospital and spoken to Ms Annett.
"(It was the) most difficult conversation of my entire life, but I needed to have that conversation," Ms Annett said.
The pair had reportedly travelled to the tropics to celebrate Ms Mitchell's cancer treatment coming to an end.
Family members, including Ms Waldron's father Pat, visited Thornton Beach after their flight to Cairns.
But Ms Annett said the crocodile shouldn't be hunted down after authorities set three traps.
The incident has prompted the state government to allocate an extra $5.8 million over three years in next week's budget for crocodile management - including comprehensive population surveys -- after Environment Minister Dr Steven Miles admitted his department didn't know whether numbers were rising or falling in parts of the state.
