The father of two of the victims of the fatal Dreamworld accident has pleaded for answers as to what went wrong.
Shayne Goodchild, whose daughter Kate Goodchild and son Luke Dorsett were among the four killed in Tuesday's tragedy, read a statement on behalf of the victim's families this morning, thanking Australians for their support.
"Like everyone else in Australia we want to know what went wrong," he told reporters in Canberra.
Mr Goodchild, flanked by his daughter's partner Dave, said the families of the victims were grateful and touched by the outpouring of grief.
Dave would not only have to deal with his grief but remain strong for their two young daughters, one of whom was on the ride when the accident happened, he said.
Mr Dorsett's partner Roozi Araghi was also killed in the accident, along with Sydney woman Cindy Low, whose 10-year-old son had also been on the ride at the time.
"So many of us like Kate, Luke, Roozy and Cindy have visited Dreamworld and sat smiling and laughing with our loved ones on the same ride," Mr Goodchild said.
His granddaughters, aged 12 years and eight months old, had lost a mother and two uncles, he said.
"Only 24 hours earlier my family were on the beach taking Evie into the waves for the very first time.
"It is truly devastating Evie will never get to know just what an amazing mum she was.
"To say this is just not fair doesn't begin to express our despair.
"We want to know why our loved ones were taken away from us in such horrific circumstances."
Mr Goodchild asked for time and space for the families to grieve and farewell their loved ones.
He declined to make any comment about Dreamworld or its owner Ardent Leisure, insisting the families would wait for the outcome of investigations.
He asked that the company and media contact them through their solicitors.
Yesterday, Ms Goodchild's mother-in-law Gillian Turner paid tribute to the young mother.
"She was warm-hearted, kind, generous, funny, quirky, and she had lots of friends," Ms Turner said.
"I would like to believe my 12-year-old granddaughter was saved so she could tell her little sister what a wonderful mum Kate was.
"She used to braid her hair for her, and she doesn’t know who is going to braid her hair for her now."
