Yes there were two distributions staggered over last week (RAAF, don't know about the others), but I don't think its Wednesday when the final word is given.
@ Mudrat - My enlistment coordinator in Melbourne told me that I would know by Wednesday as to whether or not I start on the 4th of March. I think they're cutting it fine as it is, less then 2 weeks to organise your life and work related issues is a tall order!
