There were two children on board the ride that malfunctioned killing four adults at Dreamworld on the Gold Coast on Tuesday.
Ebony Goodchild, 12, and Keiren Low, 10, were enjoying a family day out which took a tragic turn when the raft they were on on the Thunder River Rapids Ride overturned.
Their screams rang out through the popular amusement park as the vessel flipped without warning as it approached the drop off point.
Their mothers, Kate Goodchild, 32, and Cindy Low, 42, died at the scene along with Luke Dorsett, 35, and his partner Roozi Araghi, 38.
Footage of the accident captured on CCTV has since revealed how the two children escaped serious injury when four grown adults were unable to.
Ebony and Kieren were thrown from the ride and landed nearby with Queensland’s assistant police commissioner Brian Codd describing their survival as "almost a miracle."
"In terms of how they escaped, maybe through the providence of God or somebody," he told News Limited, adding, "If we’re going to be thankful for anything, I’m thankful for that."
The children's fathers David Goodchild, who was holding his younger daughter Evie at the time, and Mathew Low ran to the water side only to see emergency services pulling their wives' bodies from the water.
His father, Graham told News Limited that said his son was so distraught, he couldn’t talk about what happened and would be returning to Canberra along with his two daughters.
"They haven’t even told us completely what happened but I know that tonight there are two very traumatised children coming back home," he said.
Cindy and her son Kieran did not know the Goodchild family when they boarded the ride, her family also released a statement about the tragedy.
"The family of Ms Cindy Low has requested privacy and respect at this time of loss and sadness," the statement read.
"The family are traumatised and kindly request that their privacy be respected as they try to come to terms with this tragic loss."
The theme park is set to reopen on Friday.
