Dreamworld Inquest To Resume, With Senior Management Expected To Give Evidence

An inquest into the Dreamworld disaster has heard the maintenance supervisor wasn't aware of almost identical incidents on the Thunder River Rapids Ride.

The inquest into the deaths of Cindy Low, Kate Goodchild, her brother Luke Dorsett and his partner Roozi Araghi resumed on Monday at the Southport Coroners Court.

The four tourists died when the Thunder River Rapids Ride malfunctioned at the Gold Coast theme park in October 2016.

Team leader Stephen Murphy told the coroner on Monday he didn't realise at the time the rafts could flip if the water pumps failed.

"What would be the consequences of the conveyor continuing to work?" asked Coroner James McDougall.

"Well, we all know the consequences of what did happen that once," Murphy said.

"Were you aware of that before this happened?" the coroner asked.

"No," came the reply.

Murphy wasn't aware an almost identical collision had occurred twice before. In 2014, an operator was sacked after rafts flipped on the Thunder River Rapids Ride.

He also told the court the emergency stop switch on the main control panel wasn't subject to regular inspections.

"That button not part of our pre-operation checks."

The inquest heard it was a "badge of honour" and "competition" between staff to find problems with the rides and maintenance work  could be delayed for budget reasons.

The first two weeks of the inquest in June heard from ride supervisors and engineers who either worked at the park on the day of the tragedy or in the days preceding the event.

The second portion of the inquest is expected to hear from more senior park management including those in charge of engineering, maintenance and policy.

Dreamworld general manager Troy Margetts is expected to be called to give evidence during the two-week window.
