Russia describes its troops massed on Ukraine's border as "not a threat" but a warning against "reckless military adventures" backed by the West.
Russia's ambassador to Australia, Alexey Pavlovsky, has used a rare media conference in Canberra to warn Australian support for Ukraine risks leading to war.
"When the western countries now, including Australia, are expressing their support, either verbally or in material terms, or by sending arms to Ukraine, they embolden Kyiv to continue their line of sabotage," he told reporters on Friday.
"We think that such expressions of support are very dangerous because they lead to provocations, they lead to war."
Dr Pavlovsky also claimed Russia was not being aggressive by massing troops on the border with Ukraine.
"Our troops are not a threat. They are a warning to Ukraine not to try any reckless military adventures, not to interpret the support they have from the West as carte blanche to do such crazy things," he said.
The ambassador attacked Defence Minister Peter Dutton's earlier description of Russian President Vladimir Putin as an increasingly irrational and ageing dictator.
"If such is the level of analysis informing Australian policy, then it is definitely a worrying sign," Dr Pavlovsky said.
"Australians definitely are entitled to more meaningful understanding of the situation than comic book style propaganda like Batman versus Joker."
Australia earlier this week evacuated some diplomatic staff and their families from Ukraine and upgraded its advice to "do not travel".
Dr Pavlovsky accused the Morrison government of "fanning hysteria" from thousands of miles away.
Federal authorities earlier suggested Australia could look to help supply gas to Europe should Russia decide to cut supplies.
Dr Pavlovsky wished Australia "good luck" in entering the European gas market.
The last time a Russian ambassador to Australia held a press conference was in 2018.
