The parents of a New Zealand-born woman believed taken by a crocodile plan to travel to Queensland as authorities continue the search for any sign of her.
Cindy Waldron, 46, is feared dead after she went for a late-night dip with a friend at Thornton Beach on Sunday night and was dragged under the water.
As police and SES crews completed a second day of searching on Tuesday, New Zealand-based Pat and Heather Waldron conceded there was little they could do to help.
"We need to be there on the ground to show that we are there, that we care," Mr Waldron told the NZ Herald from their Tauranga home.
"Our darling girl is gone."
Acting Inspector Ed Lukin said teams had scoured the receding and incoming tide lines and the Environment Department organised three croc traps.
"They'll be on the water until 2am," he said.
Heavy rain has been hampering the efforts of search crews.
Ms Waldron, a photographer, had been living in rural NSW.
On a website for her business, Instinctive Images, she recalled developing a love of photography during her teenage years.
"All the hours of photography and digital imaging are worth it when I present the newly-wed couples, first time parents & extended families with their crafted images," she wrote.
"The looks on their faces tell me that they will be family treasures for years to come."
Those who knew her work paid tribute to Ms Waldron's talent.
"Your smile and enthusiasm was contagious," one customer wrote on Facebook.
Ms Waldron's friend, Leeann Mitchell, tried in vain to drag her to safety during the attack and has been left deeply traumatised.
The two had reportedly gone on holiday to celebrate the end of Ms Mitchell's cancer treatment.
The incident, which took place in an area well known for crocodiles, has reignited debate about how best to manage public safety risks.
Federal north Queensland MP Bob Katter is pushing for hunting safaris, saying croc numbers have "exploded" to unprecedented levels, partly thanks to fewer predators.
But fellow north Queensland federal MP Warren Entsch says tourists are repeatedly warned about the dangers crocs pose, and people must take responsibility for their own actions.
