SYDNEY (AFP) - A Jetstar flight from Tokyo to Australia's Gold Coast was diverted to Guam and an engine was shut down Sunday (Aug 7) after a warning light came on.

The twin-engine JQ12 Boeing 787 Dreamliner flight from Narita international airport to the Gold Coast landed on the US island territory of Guam in the Pacific on Sunday morning after an oil pressure warning light came on, Jetstar said.

"A flight from Narita to the Gold Coast was diverted this morning after the aircraft displayed an indicator message regarding oil pressure," the carrier said in a statement.

"After receiving the indicator message the captain elected to shut down one engine as a precaution. Boeing 787s can fly safely on one engine." The passengers, which the Australian Broadcasting Corporation said numbered some 320, would be taken to Australia on a flight arriving Monday.

Jetstar said the jet landed safely on Guam and was being inspected by engineers.
