if you are sponsored by NSW, or holding a state sponsor visa,you are supposed to stay in NSW for at least 2 years.In the past there were some people lucky enough to receive their citizenship even they did not stay in their designated state for at least 2 years.However, recently there was a news saying that the gov is getting strict about it.The gov may not approve your citizenship or RRV if you haven't stayed in your sponsor state for at least 2 years.
