Q: On Wednesday, Queensland specialist engineers and scientific police turned their investigation to all aspects of the 30-year-old water ride, including machine components, maintenance logs, ride engineering and the theme park's policies and procedures. Lawyers say they are bracing for several lawsuits that may cripple the park's existence and exacerbate the massive hit looming for the Gold Coast's international tourism industry, which is heavily reliant on its theme parks. Fairfax Media has uncovered several claims of serious safety mishaps, including revelations that the Thunder River Rapids ride had malfunctioned twice in three days, leaving riders stranded for up to half an hour and raising questions over whether the amusement park ride, which opened in 1986, had passed its use-by date.

 "There is a point in the ride ... just before you go up the conveyor belt where you hit a rougher part of the water and you get a jolt," she said. "Sometimes that jolt makes you bounce off your seat. On this day we hit the water so hard that it forced my son up from his seat and his seat belt became undone. My friend and I caught him mid-air and put him back in his seat." She sent a complaint to Dreamworld the next day but never heard back.

As per regulations, this safety audit was conducted by a specialist external engineering firm," she said.

"We were on the ride about an hour before the accident and we were also on the ride last week," said Joelle Verfurth. "The ride today was faster than last week and the water levels higher."

 It's understood the ride's conveyor belt broke on Sunday, leaving riders stuck for about 15 minutes. The ride broke down again on Tuesday morning and had to be drained and restarted. The Australian Workers' Union Queensland secretary Ben Swan said he raised concerns over safety issues 18 months ago but Dreamworld chose to ignore them. The complaints related to operational and mechanical faults on other rides but Tuesday's incident would "categorically ... not come as a surprise" to management, he said. On Wednesday, Dreamworld chief executive Craig Davidson was among those who laid flowers on the entrance wall. Tributes grew up to a 100 metres long for Canberra mother Kate Goodchild, her Canberra-based brother Luke Dorsett, Mr Dorsett's partner Roozi Araghi and an unrelated holidayer, New Zealand-born Sydney mother Cindy Low. 
  
 Ms Low, who was holidaying with family and friends, made the tragic decision to take the ride without her husband Mathew and six-year-old daughter Isla who said they were now suffering "intense grief". Her 10-year-old son Kieran was in the raft along with Ms Goodchild's 13-year-old daughter who were both deeply traumatised but uninjured. The mother of Ms Goodchild and Mr Dorsett also despaired at losing her two children, both Department of Human Services employees. "I have three children and have lost two of them today – my whole family has been wiped out," Kim Dorsett told News Corp. 
  
 Federal senator Sam Dastyari was one of many to pay tribute to Mr Araghi, an Australian Bureau of Statistics worker and pop music lover whose family helped the Dastyaris to migrate to Sydney. "I'm devastated that such a caring, loving, sweet and sensitive friend has been lost. I'm angry that this could happen at a venue like Dreamworld," he said. ||||| Police say raft on Thunder River Rapids ride flipped over on conveyor belt seconds from end of journey 
  
 Two children who were in the accident at the Dreamworld theme park that killed four adults had a “miracle” escape, Queensland police said on Wednesday. 
  
 The ride on the Thunder River Rapids at the Gold Coast theme park flipped as it was travelling on a conveyor belt at the end of the water-based ride about 2pm on Tuesday. Two adults became trapped under the six-person raft and two were caught in the conveyor belt.

 They have been identified as brother and sister Luke Dorsett, 35 and Kate Goodchild, 32, and Dorsett’s partner, Roozi Araghi, 38. All three are from Canberra. 
  
 The fourth woman is Cindy Low, 42, originally from Kawerau in the Bay of Plenty in New Zealand, who lived in Sydney with her family. Fairfax Media reported she was on the raft with her 10-year-old son while her partner and daughter were in another raft. 
  
 A statement issued on behalf of Low’s partner, Mathew, said the Low family was “devastated by the tragic loss”. 
  
 “The family are traumatised, and kindly request that their privacy be respected as they try to come to terms with this tragic loss,” the statement said, adding they would not make any further statements “in this time of intense grief”. 
  
 The other child in the raft was a 12-year-old girl, understood to be Goodchild’s daughter. Both children were physically unharmed but were traumatised and are in hospital and have been offered counselling. 
  
 Brian Codd, acting police commissioner for Queensland’s south-east region, said: “Maybe through the providence of God or somebody, but it seems from what I’ve seen almost a miracle that anybody came out of that,” he said. “If we’re going to be thankful for anything, I’m thankful for that.”

 Codd said the raft, or “flume”, which looks like six chairs arranged in a circle on a giant inner tube, “turned over and flipped, resulting in it falling back on top of those persons and those persons being variously caught in machinery”. 
  
 “One [raft] has flipped backwards and it has caught and tossed some of the people that were on the ride backwards on the conveyor belt,” he said. 
  
  
  
 He declined to go into any more detail but said the scene was so traumatic that it had a “deep and emotional effect” on police and paramedics. . 
  
 “I guess the fortunate thing here is that the two children managed to escape that disaster … Unfortunately, the four adults did not,” Codd said. 
  
 Goodchild had two daughters, aged eight months and 12 years. Her mother, Kim Dorsett, told the Courier-Mail that Goodchild’s oldest daughter was blaming herself. “She has had a truly terrible day. She is going through unimaginable pain at the moment,” she said. 
  
 Dorsett said she was devastated that her youngest grandchild would never know her mother. “I have three children and have lost two of them today – my whole family has been wiped out,” she said. 
  
 Codd said police had become used to dealing with tragedies such as fatal road accidents “but coming to a place where families want to come and enjoy each other’s company and just have fun doesn’t really equate to such a tragedy as we’ve seen”. 
  
 He added: “Many of our officers have families. I don’t think there’s any of our officers who haven’t [been affected by] aspects of what’s happened here. 
  
 “We owe it to the deceased and their families, we owe it to the community of Queensland, to get to the bottom of what caused this, to hold accountable any person that needs to be held accountable for this occurring, if that is the case, but most particularly ensuring that this can never happen again.” 
  
 The ride, which sends passengers around a 410-metre course of artificial rapids, was one of the oldest and most beloved in the park. It opened in 1986 and was described as one of the park’s family rides, offering a “moderate thrill” suitable for children as young as two. 
  
 The water was drained as part of rescue efforts on Tuesday. 
  
 Codd said he was aware of reports suggesting concerns had been raised about the ride in the past and said all such reports would be examined as part of the coronial investigation. 
  
 Engineers were scheduled to examine the mechanism, including the conveyor belt, on Wednesday, and investigators would also check the maintenance schedule and see whether the park had complied with its own policies. 
  
 “These types of investigations are not quick,” he said. “They take a lot of time and, unfortunately, some of that time might not be at a speed that keeps up with the media cycle. 
  
 “But I hope that you can understand that, for us, the importance is not speed, but thoroughness. It is absolutely vital that we get to the bottom of all aspects of this very, very complex tragedy.” 
  
 Some parkgoers said the ride had broken down twice earlier in the day. 
  
 Police have asked anyone who was on the ride when the tragedy occurred or earlier that day to send in any footage or photos they may have taken. 
  
 Detective Inspector Mark Thompson told reporters on the Gold Coast on Thursday that would not go into details about the investigation, saying it was “inappropriate ... when it comes to the ride or its structure or other issues surrounding the ride itself.” 
  
 But also would not say how long the theme park would remain closed, adding: “the gathering of scientific evidence will be lengthy and detailed and it would be wrong for me to speculate.” 
  
 Reports that Goodchild’s partner was robbed as he tried to assist her were false, he said. 
  
 The Queensland premier, Annastacia Palaszczuk, said the tragedy had deeply affected the Gold Coast community. “There’s been thousands, thousands of families that have been on that ride,” she told ABC’s AM. “My own family, we went on that ride ourselves just earlier this year.” 
  
 Palaszczuk said claims by the Australian Workers’ Union that it had raised concerns about the safety and maintenance of rides at the park on behalf of staff last year would be investigated. 
  
 “We need to get to the bottom of this, honestly. We need to make sure that no stone is left unturned because this is an awful, awful tragedy and we want to ensure that this never happens again,” she said. 
  
 Flowers began arriving at the site on Wednesday and Lifeline has set up a dedicated support line for people affected by the tragedy. |||||
A: 
Two Australian children are traumatized but alive after what authorities are calling a miraculous escape in Tuesday's theme park tragedy. The children, a 10-year-old boy and a 13-year-old girl, both saw their mothers die on Thunder River Rapids ride at the Dreamworld park and escaped physically unharmed, the Australian reports. The girl's uncle and his male partner were also killed when the six-person raft crashed and flipped on a conveyor belt. "Maybe through the providence of God or somebody, but it seems from what I've seen almost a miracle that anybody came out of that," a Queensland police spokesman says, per the Guardian. "If we're going to be thankful for anything, I'm thankful for that." Police are investigating the history of the 30-year-old water ride and they haven't ruled out negligence charges, reports the Sydney Morning Herald. The conveyor belt broke down on Sunday and again on Tuesday morning, and union official Ben Swan says he raised safety concerns with the park 18 months ago and they were ignored. "We owe it to the deceased and their families, we owe it to the community of Queensland to get to the bottom of what caused this, to hold accountable any person that needs to be held accountable for this occurring," Queensland Police Assistant Commissioner Brian Codd says, "but most particularly ensuring that this can never happen again."
