Cait,
I think from memory mine was +4 weeks between assessment day and receiving a letter saying my file has arrived at PSA. Not sure of the average time but you learn to be patient with DFR, they deal with a lot of people.
I am doing flight screening (DEO) in January, Maybe they aren't doing ADFA FSP courses until March, if you are applying for ADFA that could be it.
Good Luck
