Incident at Dreamworld, four killed on Thunder River Rapids

Four riders were tragically killed on the Thunder River Rapids ride today at Dreamworld.

Update 6:20pm
Contrary to reports in media, Thunder River Rapids was not shut earlier this year for a similar incident. In early 2016, the Rocky Hollow Log Ride was temporarily shut when a rider was injured. In that incident a guest reportedly ignored the attraction's signposted rules and stood mid-ride. The two water attractions use vastly different ride systems and share little in common with their conveyor belt lifts.

Update 4:30pm
Queensland Police have confirmed four adult riders have been killed.
