MH370 FBI report up to Malaysia: PM

Prime Minister Malcolm Turnbull says an FBI report into the pilot of lost flight MH370 is a matter for Malaysian investigators and doesn't shed light on the plane's location.

Labor wants the government to reveal what it knows about reports captain Zaharie Ahmad Shah used a home computer flight simulator less than a month before the aircraft vanished in March 2014.

"Even if the simulator information does show that it is possible or very likely that the captain planned this shocking event, it does not tell us the location of the aircraft," Mr Turnbull told reporters in Sydney.
