Thanks "nelleg & blossom79" for your kind response!!
I have updated Form 80 and sent back to IMMI.but problem I found is some of my pervious address,I can't remember exactly how long I was there.
also while I was in student visa and TR visa I didn't update some of my residential addresses IMMI.
I wanna ask kindly, do think it would be a problem if IMMI finds about my previous addresses weren't uptodate?
