The first funerals for passengers on board a missing Malaysia Airlines jet will be held this weekend as a Malaysian official urged relatives of those presumed dead to "face reality" and leave support centres.

Despite the most intensive search in commercial aviation history, no trace of Flight MH370 has been found since it vanished on a service from Kuala Lumpur to Beijing on March 8.

Malaysia Airlines (MAS) has said it will close assistance centres it has set up in Beijing and Kuala Lumpur for the families of the 239 passengers and crew on board.

On Friday, Malaysia's deputy foreign minister Hamzah Zainudin said:"It's about time for us to actually accept the reality that the family members should go back and wait for the answer in their hometowns."

Officials said families would be told of developments and those who qualified would receive prompt compensation.

Family and friends of Rod and Mary Burrows, two of six Australians on board the flight, will hold a memorial service in Brisbane on Sunday, according to a statement released by police.
