A Qantas flight from Dubai to Melbourne has been diverted to Singapore’s Changi Airport due to a mechanical fault.

The fault occurred about three hours into the flight, which departed Dubai at 1.05am on Monday, a Qantas spokesperson said.

The Airbus A380 is expected to return to service tomorrow.

Passengers will be booked on the next available service to their destination or provided with overnight accommodation.

“We sincerely thank our customers for their patience and understanding,” the spokesperson said.

Flight tracking site Flight Radar posted the route taken by the aircraft.

It is not the first time the airline has experienced an issue with one of its A380 aircraft.

Hundreds of Qantas passengers bound for Sydney spent New Year’s Eve stranded in Dubai due to a technical problem.

In August last year, another Qantas A380 aircraft flying from Sydney to Dubai was forced to turn back an hour into its journey following a technical snag.
