Dreamworld staffer 'trusted colleagues'

Dreamworld supervisor Sarah Cotter says a ride conveyor wasn't stopped to avert a tragedy

A Dreamworld staffer said she trusted the word of her colleagues that a ride was still safe to operate shortly before it malfunctioned and caused the deaths of four people.

Attractions supervisor Sarah Cotter told an inquest into the October 2016 tragedy on the Gold Coast on Tuesday that she had sought confirmation the Thunder River Rapids Ride was safe to operate from engineering staff.

Ms Cotter had told engineers a pump malfunction was "ridiculous" after it happened for a second time in about an hour on the 30-year-old ride on October 25, 2016.

When the engineers said the problem was fixed but the ride would be shut down for the day if the malfunction happened again, she gave the all-clear for it to resume.

About an hour later the ride's south water pump malfunctioned for a third time, leading to a collision between two rafts and the deaths of guests Cindy Low, Kate Goodchild, her brother Luke Dorsett and his partner Roozi Araghi.

Queried by barrister Matthew Hickey, representing Ms Low's family, about what led her to believe the issue had been safely resolved, she said she took the word of the engineering staff who had reset the pump.

"I was happy and had the trust in my colleagues that they knew what they were doing," Ms Cotter told the inquest at the Southport Coroners Court.

"If they (engineers) say it's safe and ready to go, I'm going to believe them."

Ms Cotter did not contact the engineering supervisor about the issue after being assured by engineers they would do so.

The inquest continues.
