Only days ago they were playing and having fun together on the beach.
Now the family of Kate Goodchild and Luke Dorsett is grappling with a tragedy that has left two young girls without a mother and two uncles.
The pair's father Shayne Goodchild, in an emotional statement on Friday, thanked Australians for their support since the fatal Dreamworld accident.
"Like everyone else in Australia we want to know what went wrong," he told reporters in Canberra.
"We want to know why our loved ones were taken away from us in such horrific circumstances.
"No one wants those answers more than we do."
Flanked by his daughter's partner Dave Turner, Mr Goodchild said the families of the victims were grateful and touched by the outpouring of support.
Dave, who was struggling to hold back tears, would not only have to deal with his grief but remain strong for their two young daughters, 12-year-old Ebony and eight-month-old Evie, Mr Goodchild said.
Ebony was on the ride when the accident happened.
"We all have to help two little girls start to come to the fact that their mum is never coming home."
Mr Dorsett's partner of almost a decade Roozi Araghi was also killed in the accident, along with Sydney woman Cindy Low, whose 10-year-old son also survived the accident.
"So many of us like Kate, Luke, Roozi and Cindy have visited Dreamworld and sat smiling and laughing with our loved ones on the same ride," Mr Goodchild 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."
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.
