Regarding 190 visa offshore candidate

Dear all,

May I ask what would be latest cut off for ICT PM for 190 visa for offshore candidate NSw?

I have 75 points with Max experience so should I hope in 3-4 months? Also pls suggest if I should hope for 491 with 80 points for same occupation? Can i expect selection immediately? Which are the best areas to settle with family and get job there ???
