A young ride operator who was working at Dreamworld on Queensland’s Gold Coast when a ride malfunctioned, killing four people, is “highly distressed” after giving evidence, saying she “would have done everything I could have” to help the victims, a court has been told.

Courtney Williams was one of two people running the ride and had been given 90 minutes of training on her first day rostered on the Thunder River Rapids ride at Dreamworld in October 2016, when two rafts collided and the four were thrown to their deaths.

An inquest on the Gold Coast is investigating the deaths of Kate Goodchild, Luke Dorsett, Roozi Araghi and Cindy Low.

Ms Williams’ barrister Peter Callaghan told the court his client was “highly distressed” and not in a good emotional state after revisiting the tragedy while giving evidence on Wednesday.

She had told the court she would not have pressed the emergency button within reach of her to stop the conveyor from moving, because she was not trained to do so.

Ms Williams told Wednesday’s hearing that she had arrived for her shift at 9.15am on October 25, 2016, and was told she was rostered as a level two operator.

She said she had not performed that role before and was given “about an hour and a half” of training.

Ms Williams told the inquest she had not remembered being shown how to shut down the ride and said she was told by a trainer about the emergency stop button who said, “Don’t worry about it, you don’t need to use it”.

She said she “didn’t know” the emergency button would stop the conveyor from moving.

“It was my first day, I wasn’t confident operating the control panel,” Ms Williams said.

At Thursday morning’s hearing, Ms Williams clarified her testimony and said: “I would have done everything I could have” to help the victims.

Barrister Peter Callaghan said Ms Williams was “mortified” to think she could have upset the family members.

‘No scenario training’ for Dreamworld staff

Senior ride operator Timothy Williams told the court on Thursday there was “no scenario training” from Dreamworld to deal with an event of rafts being stranded on a conveyor belt.

Mr Williams said he was working on the ride prior to the fatalities, when a large water pump feeding it failed.

He told the court there were rafts on the course and one on the conveyor at the time, and the operators initiated a normal shutdown procedure.

“Did you consider this to be an emergency?” Counsel assisting the coroner Ken Fleming QC asked.

“No,” Mr Williams replied.

Mr Williams was asked by the coroner about a memo sent to staff about a week prior to the fatalities directing employees not to push an emergency e-stop button unless the main control panel could not be reached.

“I felt that the language was a bit restrictive,” Mr Williams said.

“So negative as opposed to positive, is that fair enough?” coroner James McDougall asked.

“Yes,” Mr Williams replied.

The court heard there was no alarm to signal when a pump had malfunctioned on the Thunder River Rapids ride.

Mr Williams was asked by Mr Fleming how he would detect safe water levels on the ride.

“Just a stain on the wall,” he replied.
