Honorary Consul of Malaysia in South Australia Hassan Salleh said the victim's family had requested for privacy to grieve, the Malaysian Star reported.
"She was visiting relatives with her family when the tragedy struck," Hassan said.
The victim was reportedly thrown from the AirMaxx 360 ride at the Royal Adelaide Show on Friday, witnesses said. The scene was like that from a horror movie, they added.
One report said the child went flying about 10 to 15 metres in the air.
On Sunday, the show organisers said a second ride had been closed as the authorities investigated a photo allegedly showing a child on the ride who did not meet the required height specifications.
