@mslakay hi, not sure about your specific reason bakit ka NSW preferred state mo but waiting for a year is too much time wasted I think.
You are fortunate coz your occupation is available sa other states, marami dito kahit saan basta ma-invite at ma-approve. Immigration rules change a lot these days so up to you kung willing ka pa magantay ng years sa NSW. It also depends sa ultimate goal mo. gusto mo ba to be in Australia sooner than later regardless ng location or you want NSW talaga kahit 5yrs ka pa mag-antay?
Naisip ko lang if yung 1 yr na inantay mo nagtry ka sa ibang state so kahit panu naka=stay ka na ng 1 yr sa state na yun. Remember, you can move to NSW once na matapos mo ung 2 yr requirement sa 190 ng sponsoring state or after mo makuha PR mo kpg 489 naman.
