Twenty people were trapped on a rollercoaster, some for hours, at Movie World on the Gold Coast on Wednesday.
All 20 were safely rescued by around 1.30pm Queensland time on Wednesday, with the assistance of emergency services.
A spokesperson for the Queensland Fire and Emergency Service told BuzzFeed News it received a call around 11.45am reporting the trapped riders.
Sixteen of the people on the rollercoaster were able to be evacuated using existing emergency measures, while four needed special assistance from emergency crews.
"We assisted with the rescue of all persons trapped," a spokesperson told BuzzFeed News. "Four people in particular required more detailed assistance, in that they had to use specialised equipment."
Movie World general manager Greg Yong told Sky News the park needed time to investigate the mechanical issue that caused the rollercoaster to malfunction.
"These kind of mechanical issues are something that takes a little bit of time for us to investigate," he said.
"Our focus today is on the fastest way to get the guests off, and that fastest way is to do an evacuation."
The Queensland Ambulance Service remained on standby throughout the rescue operation, setting up a triage area.
The Movie World theme park is at Oxenford in Queensland, Australia. It is operated by Village Roadshow.
In October 2016, four people were killed on the Thunder River Rapids ride at Dreamworld, another Gold Coast theme park.
