Australian Federal Police have joined a fresh international search for witnesses to the downing of Malaysian Airlines flight MH17.

Officers want to know who commanded deployment of the surface-to-air missile that downed the plane over Ukraine in July 2014, killing all 298 people on board.

They are looking for information about separatists in the city of Donetsk, and their links to the decision-making in the Russian Federation on its military support to Eastern Ukraine.

"We are committed to seeking justice and I urge anyone with information on this matter to come forward," AFP Assistant Commissioner Peter Crozier said on Friday.

Four suspects were charged in June with causing the crash and murdering all of those on board.
