Prime Minister Scott Morrison says it is "nonsense" to suggest Russia is sending "peacekeepers" into Ukraine, labelling the invasion unwarranted and unprovoked.
As Russian President Vladimir Putin recognised two breakaway regions in eastern Ukraine as independent, the country's army has moved so-called "peacekeeping" forces into the area, heightening tensions in eastern Europe.
Mr Morrison hopes to see diplomatic talks prevail to prevent a conflict in Ukraine, following the movement of "peacekeepers".
