Moving to nominating state after Visa Grant

Hello guys. I hope you all are great and receiving grants without much delays. I was an onshore applicant in student visa when I lodged my 190 Visa application on May 18. Now that I have got my Visa I am confused about when to move to NSW from Vic. I am still enrolled at Deakin University and wanna complete my postgraduate degree in Construction Management. I know I have a moral obligation to reside in NSW for 2 years but I am not sure if I should move immediately or after completing my studies in May next year. Has anybody faced a similar situation? I would appreciate your thought and suggestion in this regards. Wish you all a very happy Christmas and New Year 2019. Cheers!
