It is one way to get noticed – fronting up to a Sydney courthouse dressed in military uniforms saying you've brought a message from Russian President Vladimir Putin.

So on Thursday four members of Sydney's Cossack community, dressed in military garb went to Burwood Local Court to confront a man accused of destroying 50 Orthodox Christian graves at Sydney's Rookwood cemetery.

It was a move, the Russian nationalists said, to show their community is strong and they won't tolerate such cowardly acts.

"We want to make our presence here clear, our community doesn't tolerate this," one of the men, dressed in green fatigues with Russian military patches. "We want people to understand that the Russian community is a strong community and we won't have our heads in the sand."
