Geopolitics are still in play. Why would a country that has been hammered with "Western" sanctions, and is effectively engaged in a proxy war against the "West" cooperate with the "West" when it comes to law enforcement?

That is true. I wonder though, if Russian citizens do this in the US, then there is not going to be anything done about it? What if it is an American citizen? I do not expect them to be able to spend it in the US (but I may be wrong). Would they just go to Russia or somewhere else and then use the money from those bank accounts overseas and start a new life, or what? I am just trying to imagine the scenario. I have watched The Wolf of Wall Street which was quite good. I wonder how it would usually go today, and how people get away with it, because one would think today it is not easy to get away with it. I imagine if I were to scam someone, I would get in legal troubles here, in Hungary, even if I were to send it to a bank account somewhere else in another country, is this an incorrect assumption?
I am going off-topic here, because Australia is in question here, so perhaps replace my use of "US" with Australia and "American" with "Australian".
It is called money laundering. Happens all the time. when it is an American (or Australian, German...) they just have multiple accounts in Russia and transfer the money around in Russia a bit before bring it back. You often lose a significant amount of money in this process.
There is only so much you can do - you kick them out for everything and thus further cutoff the country and that in turn means you have less influence in the future.
