When I received the AAA award last year, I got sent a letter asking for my preferred bank account for the money to deposited into, then, I think, about week 4 (I think it was roughly the beginning of April) the money will be automatically deposited, in one payment. You can choose to have your payment paid directly to your UNSW accommodation if you are living on campus. The exact date the money will be deposited will be including in the letter you receive. Hope that helps
i just found my letter from last year, and it was dated feb 1st. so unless UNSW is using a different system this year, i would think the letters may be in the post.
