Bishop welcomed news of the ceasefire, agreed on Thursday by leaders of Ukraine, Russia, Germany and France.
She insisted, however, that those who had downed the Malaysia Airlines Flight MH17 last summer be brought to justice.
She said Australia would seek clarification from Ukraine but believed the deal would have "no impact on the ability to bring the perpetrators of the downing of MH17 to justice".
"When it comes to the tragedy of the MH17, the European Union has made it extremely clear what needs to happen. We've called for international investigation, for security and full access to the crash site for all facts to be ascertained. And this remains to be the case and the responsible, of course, must be brought to justice," the EU foreign policy chief's spokeswoman, Maja Kocijancic, said at a press briefing.
The text of the Minsk accords finalized on Thursday includes, among other things, a pledge not to seek punishment for "events that took place in certain areas of the Donetsk and Luhansk regions of Ukraine".
The area is where the Malaysia Airlines flight MH17 was brought down in July 2014, killing all 298 people on board, including 27 Australians.
