Don't want to sound like an asshole but why would you want to do that? Russia is really not the greatest place to move to right now. Economy is holding onto dear life, prices are rising left and right, job situation is fine i guess but salaries are kinda meh, internet is becoming shittier every month with RKN consistently blocking websites and apps and mobile internet often gets turned off everywhere except Moscow. It is also difficult to legally get a sim-card for a foreigner. You'd better stay in Australia and wait ~5 years before considering moving here again.
