Russia cannot wash its hands of responsibility for the downing of the Malaysia Airlines jet and must fully co-operate with an international investigation into the diaster, Australian prime minister Tony Abbott said.
Mr Abbott has previously accused "Russian-backed rebels" of being responsible for the attack, which left 298 people dead including 28 Australians.
"This is a problem - a very serious problem. Australia takes a very dim view of countries which facilitate the killing of Australians," he told a press conference.
"The idea that Russia can wash its hands of responsibility because this happened in Ukrainian airspace just does not stand up to serious scrutiny. We all know what's happening in the Ukraine."
Mr Abbott said any party that attempted to block access to or contaminate the crash site was "no friend of justice" and "no friend of peace".
Thousands of online users have taken to social media to call for the victims of the Malaysian airliner crash to be returned to loved ones.
United States intelligence officials admitted that they do not know who fired the surface-to-air missile that downed flight MH17.
