Thunder River Rapids Ride On October 25, 2016, four people — two men aged 35 and 38, and two women aged 32 and 42 — were killed when the raft they were riding hit another stopped raft, causing it to flip. Eyewitness accounts noted that the water level in the channel had dropped before the incident, but the drop did not trigger a sensor that would have stopped the ride. Investigators believe that the occupied raft was pushed up onto a stopped raft by a conveyor belt, at first mounting the stopped raft then flipping over. Of the six passengers aboard the raft, two children aged 10 and 12 were ejected from the raft but survived, while the two men were believed to be crushed under the raft and the two women were trapped underneath the conveyor belt. Dreamworld officials stated that the ride had just passed its annual inspection in September. On November 9, Ardent Leisure chief executive Deborah Thomas announced that the ride would be permanently closed and demolished. The park was closed for six weeks following the accident.

An investigation revealed that the ride derailed due to a broken axle. None of the ride vehicle's axles had been replaced for fifteen years. Following this accident, similar coasters at other Japanese parks were voluntarily shut down and inspected to see if they could have the same axle flaw. Expoland was cited by authorities for faulty maintenance when similar axle cracks were found on a second train a month later. On July 15, 2008, three former Expoland employees — the director and administrative manager, the head of facility and business department, and the head of the technical division — agreed with the allegation of professional negligence and violating Building Standards Law. They admitted to purposefully postponing the coaster's regular inspection,
