Thrill-seekers have been stranded in the hot sun as two rollercoaster stopped mid-ride at a Gold Coast theme park.

Two rides at Sea World are reported to have stopped working mid-ride, leaving people stuck as temperatures in Queensland’s southeast soared on Thursday afternoon.

Video of the incident shows people stuck on the rides while witnesses watched on helplessly.

One person said they were told by staff both rides broke due to mechanical faults, leaving only one adult ride open during the busy school holiday period.

One patron told 7NEWS they waited up to an hour to get on a ride before being told to leave as the ride was not operational.

Sea World has been contacted for comment.
