Dreamworld inquest: Ride inspector 'had no confidence' in procedures

Further Workplace Health and Safety bosses will be grilled at the inquest into the Dreamworld disaster today, after a leading inspector admitted he had "no confidence" in the emergency procedures in place on the Thunder River Rapids ride.

Ian Stewart spent 10 days at the theme park following the tragedy which killed four tourists in October 2016, telling the inquest yesterday he was "amazed" at the amount of corrosion on the ride and mentioned there were "bits of timber holding it up."

He found 90 safety concerns, and snapped 500 photos of things he believed were issues.

Two weeks later he issued Dreamworld with a prohibition order.

Mr Stewart also mentioned the type of ride the Thunder River Rapids was, is quite "common throughout the world" but claimed the attraction at Dreamworld had an unusual conveyor "none of them have slats like that."

The inspector faced tough questioning from lawyers acting for Dreamworld's parent company Ardent Leisure, who accused Mr Stewart of using the "benefit of hindsight" when crafting his report into the tragedy.

But Mr Stewart hit back "I did not write a report saying 'they're guilty and I'm going to prove it that way'.

Today Chief Engineer for WH&S Michael Chan is due to give evidence.
