A major overhaul of all theme park safety including mandatory major inspections has been proposed following the Dreamworld tragedy which claimed four lives.
Workplace Health and Safety executive Bradley Bick told the inquest which resumed on Thursday the recommendations included regulatory amendments to improve amusement device safety.
Mandatory major inspections every 10 years, ensuring competent and properly trained staff operate the rides and theme parks prepare a safety case to protect visitors are also proposed.
Inspections would involve a thorough examination of critical components, stripping down devices, removing paint, grease and corrosion to ensure "effective and safe operation" of all theme park attractions.
Mr Bick said ride operators would be tested to ensure they were competent to operate the attraction.
WPHS officers will also introduce "spot checks" to ensure theme parks adhere to strict safety guidelines.
"This will provide a comprehensive physical check of the ride to ensure that the ride is safe," Mr Bick told the inquest.
A code of practice to force theme parks to adhere to a minimum standard will also be introduced which theme parks will be expected to follow.
There is no time frame for the regulations to take effect, the recommendations are in draft form and will not go before the state government before March.
The inquest was told the role of a public safety ombudsman could be introduced to investigate theme parks.
The inquest into the deaths of Cindy Low, Kate Goodchild, her brother Luke Dorsett and his partner Roozi Araghi has been set down for the last days of testimony which are expected to be the final sittings before coroner James McDougall is expected to hand down a decision in 2019.
The four holiday-makers were flung into a mechanised conveyor when the raft they were riding collided with another raft on Thunder River Rapids ride and partially flipped on October 25, 2016.
Ms Goodchild's 12-year-old daughter and Ms Low's 10-year-old son survived the incident.
