Four persons lost their lives on the Thunder River Rapids attraction at Dreamworld on the Gold Coast of Queensland on October 25, 2016. A raft capsized. A conveyor mechanism ensnared two persons. The park was cleared out. Dreamworld closed permanently in a matter of hours. The subsequent inquiry, which resulted in a Queensland coronial inquest that lasted for years and included hundreds of pages of findings, uncovered systemic flaws that went far beyond a single technical breakdown on a single afternoon. There were gaps in the maintenance records. There was uneven staff training. Risk evaluations had not kept up with the equipment’s age. The inquest looked at more than simply what went wrong that day. It investigated the long-standing issue.
The ensuing regulatory reaction was significant. A formal Amusement Devices Code of Practice, supported by a Safety Case and a licensing framework for major parks, was the result of what authorities referred to as a Best Practice Review of Australia’s theme park business. These weren’t rules. These were mandates, and WorkSafe Queensland was the enforcement agency with the actual power to shut down rides and cancel operating permits.
The ten-year major examination is the most important structural requirement. The new framework requires amusement rides to go through a thorough engineering inspection once every ten years. This inspection is not a routine check, but rather a partial or complete disassembly of crucial components, evaluated by expert engineers. That’s a substantial recurring expense for a park with dozens of rides, many of which have been running for twenty or thirty years. Economically, some older attractions won’t make it through the process. Operators are essentially forced by the inspection requirement to decide whether to spend in the whole examination and any necessary remediation or to retire each aging ride. The latter has been subtly carried out in a number of parks.
The Safety Case requirement altered the way large parks handle risk management and documentation. A Safety Case is an ongoing document. An integrated risk assessment framework is a dynamic system that needs to be updated, maintained, and clearly linked to everyday operational choices. It can be audited by regulators. It is a violation in and of itself if it does not accurately reflect what is actually occurring on the ground. The change has been substantial for parks that previously maintained safety records as a paper exercise rather as a true operational tool.
Another weakness the inquest found was filled by mandatory operator training and competency evaluations. Prior to the revisions, ride operators’ knowledge and training differed greatly between parks and particular locations. Documented training, competency assessments, and documents that inspectors may verify were all standardized under the new rules. A seasonal worker managing a large vehicle must now show that they comprehend the system they are in charge of, not merely that they have been shown where the stop button is.
The daily logbook obligations are important but unglamorous. Each pre-opening inspection, both with a loaded and an empty ride, needs to be documented. All information is tracked, stored, and made available for regulatory scrutiny, including maintenance history, prior enforcement notices, and any anomalies. One of the things that made the Dreamworld study so challenging was the lack of that kind of documentation. Simply put, records of what had been known and when had been lost.
It is more difficult to determine whether the reforms have completely altered the industry’s culture as opposed to just its documentation. It is possible to measure compliance. Culture isn’t. It is plausible to argue that if the structural criteria are applied consistently over time, the culture change they are intended to promote will eventually result. The more challenging question is whether the regulations’ enforcement capabilities are adequate to fill up the gaps between inspections. Regulators and the industry are still debating that issue.
