A Qantas spokesman said the A380 aircraft experienced an engine problem soon after taking off from Singapore on a flight to Sydney. The plane had 433 passengers and 26 crew on board.
Qantas spokeswoman Emma Kearns said one of four engines on the plane shut down.
Ms Kearns said the plane can safely fly on three engines, but that the pilot landed the plane in Singapore to be safe.
She said there have been no reports of injuries and the airline has not received any reports of an explosion on board.
A Qantas statement said: "The aircraft landed safely at 11.45am local time.
"Some media reports suggested the aircraft had crashed.
"These reports are incorrect. No Qantas aircraft has crashed."
Witnesses on the Indonesian island of Batam near Singapore reported hearing a large blast and seeing pieces of debris - including panels painted white and red - falling onto houses and a nearby shopping mall.
