A new eye-witness account of the Dreamworld tragedy has emerged: "They didn't stand a chance."

The trauma of the Dreamworld tragedy is far from over, as people who were at the theme park on the day come forward with their stories.

Ben, a 28-year-old man, was waiting in line for the Thunder River Rapid Ride when the unimaginable happened.

But, that wasn’t the first time he had seen the family that day.

As they were on the road, he was crossing the footbridge above the right and looked down to see all six of them having a great time on the ride.

“I remember thinking, ‘Isn’t that great? They’re all laughing and soaked with water’. They were just having the time of their lives,” Ben told the Gold Coast Bulletin.

The victims on the ride.

While looking at the ride, he noticed how low the water levels were. Ben regularly went to the theme park with his daughters and it just didn't seem right.

"Like when you see the tide roll out, the level of the rapids was quite low compared to the water mark on the wall.

"It was like a pool that obviously needed to be topped up."

Despite his concerns, the father of two little girls decided to line up for the ride.

He noticed that an empty raft was stuck at the end of the conveyer belt but he thought the raft coming would bump it out of the way.

But, it didn't.

"The two men were sitting at the back of the tube, so they just went straight between two conveyor belts. I knew in my mind they didn't stand a chance."

Ben thought the two women may have been able escape. They were tossed from the ride and into the water, and he hoped they would find a way out.

How the children survived is a mystery to Ben, who didn't see them after they were flung out of the raft.

"It took some time to drain the water and the [partner] of one of the women was trying to climb down to get her. He was covered in dirt and I remember him trying to hold her in his arms."

The woman being held onto was Kate Goodchild, whose partner had decided to wait by the side of the ride to care for their baby daughter.

It was Kate's other 12-year-old child who was in the ride with her, and the one everyone, including Ben, heard screaming, "Where's my mummy? Where's my mummy?"

"It all happened in a matter of seconds and whether someone pushed a button or not, nothing could have stopped it."

Since that day, Ben has been recounting his stories to trained counsellors on Lifeline, which has been set-up to talk directly with the victims of Dreamworld's horror.

"No one wants to see a family go through this, especially when they've come to Dreamworld for happy day full of joy.

"They were on holidays and no one thinks they won't be going home."
