If you're in a hurry to get your private concession card it may be a good idea to go directly to your closest depot, that's what I do to get my busways concession, they do it right in front of you...all you have to do first is fill out the little pink form from the student centre and get it stamped there. Then you can post it, or take it the depot. Either enclose or take a passport photo of yourself with you...as this will usually be glued to your concession card as proof of your identity when you go to use it.
