The family of Dreamworld victim Cindy Low say they are traumatised by her death as they ask for privacy while they grieve.
The 42-year-old New Zealand expat was killed alongside Canberra residents Kate Goodchild, 32, her brother Luke Dorsett, 35, and his partner Roozbeh Araghi, 38, when the Thunder River Rapids ride malfunctioned on Tuesday.
Ms Low's 10-year-old son survived the ride, as did a 12-year-old girl.
"Ms Low's family was devastated by the tragic loss of partner and mother Cindy Low, who was killed in the catastrophic incident at Dreamworld," the family said in a statement released to the public on Wednesday afternoon.
"The family are traumatised, and kindly request that their privacy be respected as they try to come to terms with this tragic loss."
On Wednesday Australian writer Richard Cooke, who was a close friend of Mr Araghi, published a moving tribute.
"He was hilarious and unfailingly kind, and had a way of dealing with idiotic opinions that I grew to respect enormously, patient and a bit ironic at the same time.
"It wouldn't be quite right to say that he mellowed with age (he was always too much fun for that), but that generosity expanded, and the encyclopaedic knowledge of pop culture never shrank. What a combination."
The two young children who survived Dreamworld's horrific raft ride accident will have the theme park's "full support into the future", chief executive Craig Davidson says.
Mr Davidson joined a group of staff to lay a wreath near the Gold Coast park's entrance on Wednesday as the ride remained a crime scene.
He said the team's immediate focus was on the families and friends of the victims.
"I also want to specifically acknowledge the impact of the event on the two children who were involved in this tragedy," he said.
"These children will have our full support into the future."
Police have said the children's survival, given what they viewed on CCTV footage of the accident, was miraculous.
Mr Davidson said the accident had affected the entire Dreamworld family, its guests and the emergency services personnel who responded to the terrible scene.
"Dreamworld is absolutely committed to fully supporting the authorities investigating the incident so we can find out exactly what has occurred," he said.
