The Dreamworld ride which killed four people in 2016 broke down twice earlier on the day of the fatal accident, an inquest into the theme park incident has heard.

The ABC reports that Detective Sergeant Nicola Brown revealed a large pump on the Thunder River Rapids ride had failed at both 11:50am and 1:09pm without any incidents.

“Engineering attended, reset the pumps and operating continued as per normal,” she said.

But at 2:30pm a pump failed again causing a drop in the amount of water, which in turned caused the raft to become caught on rails.

The raft then collided with an empty vessel and flipped backwards, killing the four adults onboard.

Two children managed to escape moments before the accident.

The counsel assisting the inquiry, Ken Fleming QC, said, “the tragedy of this event has been felt Australia-wide.”

Almost 40 witnesses will be called to give evidence at the inquest over two weeks.

Following the deaths, Ardent’s theme park revenue fell as much as 63%.

The ABC has more.
