Most of Defence is on stand down now. Offers would have already gone out for the various positions given SSTs start in Jan (ADFA). With regards to the Navy offer, if RAAF doesn't want him but he has a 4 down, then next dibs go to Navy. They would have been under the pump to get the spots filed before stand down hence the take it or leave it. For future reference, the only numbers you should use in your preferences is a 5, 4 or a 1.
