Operator tried to stop ride 'two or three times'

A DREAMWORLD ride operator says the same sort of malfunction which led to the death of four guests on the Thunder River Rapids ride occurred while he was working on the attraction a week earlier.

Peter Nemeth was operating the ride when two rafts collided in October 2016, throwing guests from a raft and into a conveyor mechanism.

Cindy Low, Kate Goodchild, her brother Luke Dorsett and his partner Roozi Araghi all died instantly in the incident.

Mr Nemeth told an inquest at Southport Coroners Court on Tuesday in the moments before the tragedy he'd noticed the water levels on the ride had dropped dramatically.

He said he knew one of the water pumps on the ride had failed.

"The railings were already exposed by the time I noticed," Mr Nemeth said. "I knew what was happening because it happened a week before."

After noticing the raft containing the guests was about to collide with an empty raft stuck on the railings he pushed a button on his main control panel to stop the conveyor belt.

"It did not stop even though I pressed it two or three times," Mr Nemeth said. "It did stop after the rafts had collided."

Earlier on Tuesday, a forensic crash investigator said his investigation had indicated the button had been pushed after the rafts had already collided.

An emergency stop panel at the nearby unloading dock, which would have stopped the raft conveyor belt in just two seconds, wasn't pushed at all, the inquest heard.

Senior Constable Steven Cornish said that emergency button could have lessened the likelihood of death, even if it was pushed after the collision.

"It wouldn't have avoided (the tragedy), it may have limited some injuries. Possibly," Sen Const. Cornish said.

On Monday lead police investigator Detective Sergeant Nicola Brown told the inquest Mr Nemeth panicked during the tragedy and "wasn't sure at the moment of stress which button to press".

Mr Nemeth told the inquiry there was no doubt he'd been pushing the correct button in the moments before the tragedy.

"There's only one button that stops the conveyor … I was pushing the red stop button," he said.

The inquest continues.
