A Papua New Guinea museum has removed a display that included what is thought to be the skull of an Australian World War II soldier.
A spokesman for the Veterans' Affairs Minister De-Anne Kelly says Australia's defence attache in PNG visited the museum and asked the curator to remove the remains.
He says the defence attache expressed Australia's desire that the skulls not be displayed and the curator has actually withdrawn the skull from the display.
The spokesman says the local community elders have apologised for any offence caused.
He says the Defence Department and the Office of Australian War Graves are investigating whether the skull belonged to an Australian.
It was reportedly found near an Australian soldier's kit and weaponry.
